Thank you. Good morning and welcome to Hydro's Q1 2021 presentation and conference call. We will start off with a presentation, followed by a Q&A session. Our CEO, Hilde Merete Aasheim, will start the presentation, followed by our CFO, Pål Kildemo. The presentation slides we will walk through can be seen on the webcast. The link to the webcast, as well as the slides, can be found on hydro.com. Please note that you will need to dial into the conference call to be able to ask questions at the end. It's not possible to ask questions over the webcast. If there are any media inquiries for one-on-ones with Hilde or Pål after the presentation, please contact our Head of Media, Halvor Molland. With that, I turn the microphone over to you, Hilde.
Thank you, Eline, and good morning and welcome from me as well. Let me start with the highlights for the quarter. Next slide, please. I'm pleased to see earnings and returns picking up across most of our operations on higher margins and volumes, but also on continued low costs, especially in Extrusions. For Q1, we report an EBITDA of NOK 5.2 billion, while free cash flow came in at NOK -0.8 billion, mainly driven by seasonal working capital build. In the first quarter of 2021, we saw a strong global recovery driven by the reopening of economies and substantial fiscal stimuli. As a result, we saw a decreasing oversupply in primary aluminum markets, and analysts now expect a largely balanced market for 2021. Hydro Extrusions achieved a record result this quarter, driven by strong volume growth, improved margins, and continued cost savings from improvement program initiatives.
Hydro Energy also experienced a record quarter driven by higher power prices, production volumes, and the expiry of legacy power contracts. I'm also pleased to see that our improvement program is ahead of plan and continues to be a focus area throughout the whole organization. A milestone in this first quarter was the announcement that Hydro entered into an agreement to sell its rolling business to KPS Capital Partners. Completion of the transaction is expected to take place in the second or third quarter of 2021. The sale of rolling will strengthen our ability to deliver on the 2025 strategy. Another important milestone this quarter is that we have made the investment decision for the FuelSwitch project at the Alunorte refinery in Brazil. The FuelSwitch project is an important enabler toward reaching our climate target to reduce our CO2 emissions by 30% by 2030.
Hydro set out a clear strategic direction towards 2025, where we aim to strengthen our position in low carbon aluminum while exploring new growth opportunities in renewable energies. The new growth initiatives within Hydro Energy are progressing well, and last month, we announced our interest for hydrogen. We see a large potential for hydrogen replacing natural gas at our plants, and by that, reducing our climate footprint. We will explore the potential for developing and operating hydrogen facilities to meet the internal demand, as well as serving an external market, leveraging the company's industrial and renewable power expertise. Let's turn to the next page, please. Health and safety is our top priority in Hydro, both for our employees and the communities where we operate. An injury-free environment is our ultimate goal, and we are continuously working to avoid any incident to happen.
Hydro's operations have been operating largely as normal during the quarter, with strict COVID initiatives to support employees and prevent infections. I'm very impressed about how our organization and employees have handled the COVID situation. We have been able to keep the wheels turning while dealing with the most challenging global health crisis in a century. Currently, Brazil is among the countries being impacted the hardest. Hydro is providing a lot of support to our own employees as well as the local communities in Brazil in their efforts to handle the pandemic. Please turn to the next page, please. Have a look at the financial highlights for the quarter. Since we signed an agreement to sell rolling in March, we have excluded rolling in the majority of consolidated numbers throughout the presentation.
As I said, adjusted EBITDA came in at NOK 5.2 billion, up from NOK 3.8 billion in the same quarter of last year, reaching the highest level we have seen since Q4 2017. Our free cash flow decreased mainly due to working capital build from seasonality and high activity levels. We are pleased to see a positive trend in the 12-month rolling ROACE from 3.7% at Q4 2020 to 5.4% at Q1. For the quarter alone, the ROACE was 13%, and if I use spot assumptions, we are currently around 15%. We set an ambitious 10% ROACE target over the cycle in 2019, and we are well on our way to deliver on this now. Upstream costs increased some in the quarter, both in D&A and Aluminium Metal, mainly driven by higher prices for raw materials. Volumes in Hydro Extrusions increased by 16% from Q4 levels and 11% from Q1 2020.
Lastly, I'm very happy to see that our improvement program is on track and looking to exceed full-year expectations, driven mainly by continued low-cost levels in Extrusions. Turning to next page. Our stronger results are supported by the global recovery, which is well underway. Driven by the reopening of economies and substantial fiscal stimulus, the IMF is now expecting the global economy to grow by 6% in 2021, the strongest expansion ever recorded. On the back of this, global aluminum demand is expected to grow by over 9% in 2021, supported by the reallocation of consumption from the service to the industry sector and metal-intensive infrastructure stimulus packages. In Q1 2021, primary aluminum markets in the world ex China has been in a deficit, driven by stronger than expected demand recovery and China importing this quarter.
China experienced a surplus of aluminum in Q1 2021 due to seasonally low demand during Chinese New Year, but it is expected to turn into a deficit market over the upcoming months on continued strong demand. While demand is strong in both China and world ex China, there are substantial production additions expected in both regions. Projects in Yunnan province in China are being ramped up, leading to 7% expected production growth in China this year. Both HARBOR and CRU expect strong demand growth in 2021, both in China and world ex China. Overall, analysts are expecting largely balanced markets for 2021. Please then turn to the next slide, please. The strengthening markets are driven by existing but also new trends supporting demand for aluminum. Sustainability and climate change are increasingly important in the aluminum industry.
From the demand side, aluminum is expected to play a bigger role in the green transition through, for example, higher aluminum content in electrical vehicles, but also higher end product adoption due to recyclability. In this context, we are very pleased to see that primary aluminum based on renewable power and recycling will qualify under the new taxonomy criteria communicated by the European Commission last week. From the supply side, it becomes clear that the aluminum industry has to transform in order to reduce its carbon footprint. In the future, it will most likely become increasingly difficult to get financing for smelters not based on low carbon energy sources, potentially lifting the CapEx for new projects. Also important in this context is the development in China. The Chinese government has set targets for peak carbon emissions in 2030 and net zero emissions in 2060.
There is a growing pressure on the provinces to decrease energy consumption, which has led to production cuts for the aluminum industry in Inner Mongolia, and other regions may potentially also become impacted going forward. Further supply restrictions could transform the Chinese market into a deficit market for primary and reduce the risk of sustained overcapacity the next decade. Please turn to the next page. The strong recovery in demand is very visible in our extrusion sales volume. The markets are performing ahead of industry forecasts for the quarter, with CRU estimating a 6% demand increase compared to the same quarter last year in both Europe and North America, while the forecasts going into the quarter were 2% and 7% respectively. The strong performance in Q1 is partly due to seasonality.
However, underlying demand has continued to improve, especially for the industrial and automotive segments, even though the latter segment is impacted by semiconductor shortage, especially in North America. Hydro Extrusions sales outperformed the market, delivering 11% growth compared to the first quarter 2020. All market segments are currently showing strong demand, impacting both volumes and margins. Automotive and transport showed their strongest growth, but the heat exchanger market and building and construction are also showing an increase versus the same period last year. CRU estimates that the demand for extrusion will increase around 36% in North America and 30% in Europe in the second quarter 2021 compared to last year. We expect our volumes to grow even more than the overall market due to strong current momentum in some of our key segments. Now let's turn to the next page.
First quarter marked a record quarter for Hydro Extrusions, delivering an adjusted EBITDA of NOK 1.7 billion, compared to previous record quarters of around NOK 1.4 billion. The positive performance was driven by strong volume growth, improved margins, and continued cost savings from improvement program initiatives, in particular relating to procurement and SG&A costs. The restructuring work done in the previous years is also contributing significantly to the bottom line in 2021. The quarter also saw a strong rebound in automotive sales in Europe and solid growth in the industrial segment and residential building and construction. Strong production levels at recycling units also positively impacted results and was a key source of internal billet supply, given the tight billet market in both Europe and North America.
Going forward, we see the strong momentum continuing, and as long as we can get our hands on the metal needed to meet customer orders, we should see a strong increase in results also in the second quarter. Let's turn to the next page, please. If we then move over to the strategic update, we have set a clear strategic direction for the company towards 2025 and aim to strengthen our position in low-carbon aluminum while exploring new growth opportunities in renewable energy. The first pillar builds on our strengths, and we continue to improve our position as a low-carbon aluminum producer based on solid cost-efficient asset base and a strong market position. We continue our efforts to differentiate on the sustainable footprint of our products offering, including Hydro CIRCAL and Hydro REDUXA, and we are also progressing on growing our recycling capacity.
In pillar two, we are looking beyond aluminum to diversify our portfolio with new energy. Since our Capital Markets Day in December 2020, we have introduced hydrogen as a third energy growth area. For EU and the industry to meet their climate ambitions, we see a substantial potential for industrial hydrogen consumption. Taking a developer and operator role in hydrogen sector represents an opportunity for Hydro to reduce industrial CO2 emissions and develop a profitable and sustainable business based on hydrogen. Let me start with giving an update on our first pillar. Turning to the next page, please. In order to strengthen our low-carbon aluminum position, a strong cost and improvement focus is essential. I'm pleased to see that the improvement program is continuing with full speed.
In addition to the continued low cost levels in extrusion, the ramp-up of volumes in our upstream operation, which is coming at full speed this summer, improving operational parameters and an ambitious procurement efforts across the company are contributing positively. The total improvement target has been adjusted for the sale of Rolling and the updated target of NOK 7.4 billion to be delivered by 2025. It is a front-loaded program and is targeting an accumulated NOK 5.1 billion improvement to be delivered at the end of 2021. The commercial ambition has been adjusted to NOK 1.5 billion. While markets and earnings are improving significantly, we will continue to focus on continuous improvement, securing our position on the cost curve, while at the same time focusing on how we go to market, growing our market share, and expanding our margins. Please turn to the next page, please.
This quarter, we saw a strong demand for our low-carbon aluminum products, Hydro CIRCAL and Hydro REDUXA, with the volume of Hydro REDUXA sold in the first quarter being approximately 60% of the total Hydro REDUXA volume sold in 2020. One example that we are pleased with is that Hydro REDUXA will be used for Google's new office building at Hudson Square in New York City. The 1.3 million square foot office will contain 450 tons of Hydro REDUXA. The aluminum billet for the new Google office is produced at our Hydro Sunndal plant in the western Norway. Sunndal is the largest of our five primary production plants in Norway, where 700 highly qualified employees produce more than 400,000 tons of primary aluminum based on hydro power per year.
The Sunndal billets are then shipped to our extrusion plant in Hydro Atessa in Italy, where they are extruded into profiles and customized to become WICONA double-skin facade, before finally assembly and installation is done by our project partners. The Google Hudson Square project show how our global value chain and areas of competencies are linked, helping our customers to meet their sustainability ambitions. Let's turn to the next page, please. Sustainability is the basis for our future positioning and embedded in our strategy of lifting profitability and driving sustainability. We are continuing our efforts to drive change in key areas, including social responsibility, environment, and climate. With our social responsibility strategy, we aim to make a positive difference by strengthening our business partners and the local communities where we operate.
We target the fundamental drivers of long-term development to contribute to education and capacity building for 500,000 people by the end of 2030. The start of 2021, we have passed 100,000 people, meaning that we are well on track for our 2030 target. The biggest share comes from our efforts in Brazil. In the environment, I'm very excited about our latest development related to our tailing storage facilities in our mining operation in Paragominas. We have invested in an industry pioneer project to eliminate the need for new tailing storage facilities. The methodology eliminates the need for continued construction or upgrade of new permanent tailing storage and will enable us to operate more safe with reduced footprints and more swiftly deliver on our one-to-one rehabilitation target.
The operating license to implement this new concept was received in December 2020, and it has now been fully adopted into operations at the Paragominas mine. What I also find very exciting is that the project is estimated to also have CapEx savings of around BRL 2 billion over the next 10-15 years. Our climate strategy, 30 by 2030, targets a 30% reduction of own greenhouse gas emissions throughout the aluminum value chain by 2030. We will do this through greener sourcing, greener production, and reducing the carbon footprint on the products we deliver to our customers. An important milestone project to reach our climate goal is the FuelSwitch project at Alunorte in Brazil. I will talk more about that on the next slide. We're also working beyond the 2030 target.
Currently, we are working on several technology and innovation paths to see how we can get to a net zero situation by 2050. We are exploring now different pathways for the electrolysis, such as carbon capture and storage, biomass anodes, and a new carbon-free chlorine process. Our new opportunities in hydrogen will also contribute positively, together with our existing ambitions using more renewable energy. Please turn to the next page. Today, we are pleased to announce that an investment decision has been made for the Alunorte FuelSwitch project, which is one important enabler to deliver on our 2030 CO2 reduction target of 30%. By replacing a large portion of the current fuel oil consumption at the refinery with LNG, we expect to unlock a potential of 600,000 tonnes of CO2 emissions reductions. The CapEx expected for the project is BRL 1.1 billion.
Hydro is supporting use of LNG and natural gas in the state of Pará. Our access to LNG will not only enable more sustainable operations for Hydro, but also give access to natural gas for other industries and consumers in the region. Earlier in April, Hydro and New Fortress Energy signed an MoU for the delivery of liquid natural gas to Alunorte, with expected first delivery next year. In 2021, we're also planning the first pilot installation of three electrical boilers in Alunorte, with the potential of 400,000 tons of CO2 reduction. We further work on potential for eliminating coal as power source in the remaining boilers by 2030, which has the potential of up to 2 million tons of CO2 reduction.
With the FuelSwitch project, the CO2 footprint of producing Hydro REDUXA will go from today's below four kilos CO2 per produced kilo of aluminum to 3 kilo. With the further electrification of the boilers at the refinery, then the CO2 footprint producing REDUXA could be as low as 2 kilos of CO2 per produced kilo of aluminum. Before I leave the sustainability area, I would like to comment on a lawsuit filed against Hydro in February in the Netherlands by a Brazilian group called Cainquiama. The lawsuit filed against Hydro is related to allegation against our local operations in Barcarena in Brazil of sustained harm to local environment and health. The matters are already being discussed before Brazilian courts and authorities. We do not see that there is a link between the allegations made in the lawsuit and our operations in Barcarena.
Even if we do not recognize the allegations, the lawsuit still illustrates the scrutiny and very high expectations to Hydro, which emphasize the importance of our sustainability agenda and which is our license to operate. Let's turn to the next page. Recycling will play a vital role and vital part in the transition towards the low carbon economy. Recycling has a great potential for Hydro, both from sustainability and profitability perspective. As communicated at Hydro's Capital Markets Day in December, we have an ambition to grow the current recycling business substantially, to double our use of post-consumer scrap by 2025. Recycling is already an important part of Hydro's value proposition, creating a solid foundation for further growth. Currently, we have 25 recyclers in operation in the business areas Aluminium Metal and Extrusion combined, of which 11 is in the U.S. and 14 in Europe.
The capacity of these plants combined is approximately 2 million tonnes annually, and consists of recycling of both process and post-consumer scrap. By the way, recycling of process scrap does not help the green transition, and Hydro advocates for common standards that will ensure that the use of recycled aluminum in the marketplace actually contributes to reduced emissions. The most important contribution to the circular economy and reduced emission is to ensure used scrap comes back into use. This is at the core of Hydro's recycling strategy. We see an EBITDA uplift potential of NOK 700 million -NOK 1,100 million in our project pipeline after excluding the rolling numbers. We have already several projects now on the way, including recycling of post-consumer scrap at our Norwegian smelters, with the initial ambition of adding up to 10% to our primary production capacity in Norway through scrap coming back after use.
The project pipeline for investment decision and other early phase projects include greenfield projects, larger brownfield projects, and we're also evaluating M&A opportunities. These initiatives will have a total CapEx frame on NOK 3 billion-NOK 4.5 billion up to 2025. Let me move to an update on our second strategic pillar, new energy. Turning to the next page, please. Hydro has unique capabilities that set us apart from other industrial players due to our own existing renewable power position and industrial competence, as well as large internal demand for renewable power. We have now expanded our portfolio to also include hydrogen in addition to already announced areas such as renewable growth and batteries. Please turn to the next page. Hydro Rein is our newly established and dedicated company for development of new renewable projects.
Rein takes a customer-centric and market-driven approach to project development, finding the best combination of forces and submarkets to increase value for projects and customers. In Brazil, that means combining wind and solar projects to create a balanced portfolio. For example, the project that Hydro Rein is looking at together with Macquarie is a 620 MW hybrid wind and solar project. In the Nordics, Hydro Rein is assessing opportunities for wind, primarily in Norway and Sweden at this stage. This includes also the opportunity to enter into offshore wind, a segment we consider to have significant growth potential and that we expect will become a key part of the future global energy mix. We are progressing well towards the target of having an investment decision into at least 1 GW gross installed capacity in 2021.
To date, Hydro Rein has screened more than 20 GW of projects in Brazil and 7 GW in the Nordics. MoUs are now in place on projects totaling about 1.4 GW gross installed capacity in Brazil, including a new MoU signed in April for a 300 MW solar project in Southeast Brazil. Hydro companies have an aggregate repowering need of 10 TWh by 2025, of which about 9 TWh in Brazil and 1 TWh in the Nordics. Our ambition is for Hydro Rein to supply as much of that need as possible based on competitive renewable projects. To do that, Hydro Rein will capitalize on Hydro's more than 100 years of experience in power systems, from production, operations, and trading to industrial sourcing and consumption. Hydro Rein also relies on partnering with industry leaders such as the partners that we already have MoUs with.
In addition to developing renewable capacity, Hydro Rein will help Hydro and external customers succeed with the energy transition through delivering industrial-scale energy solutions and services to both improve energy efficiency, reduce emissions, and to reduce costs. This includes services related to sourcing of renewable energy, on-site generation, storage solutions, and energy efficiency measures. As communicated at Hydro's Capital Markets Day in December 2020, Hydro is evaluating to raise external capital and pursue a separate stock listing for Hydro Rein. Now let's move to our second area within New Energy, which is the batteries. Please turn to the next page, please. The battery team is progressing as planned towards building a portfolio of battery companies. Corvus Energy, where Hydro owns 21%, delivers battery systems to the marine sector. Recently, the company started the development and production of large-scale maritime certified hydrogen fuel cell system with Toyota as a key partner.
Corvus Energy has also recently signed a joint venture agreement with Sumitomo Corporation, a 50/50 ownership for marketing and sale of Corvus Energy battery system and fuel cell system in Asian markets, mainly in Japan. The Hydrovolt, the EV battery recycling pilot, is progressing well, as has now been financed with a combination of bank debt and Enova support, resulting in limited need for equity at this stage. Our piloted approach and technology within EV battery recycling has an exciting rollout potential into Europe, and we also see synergies with Hydro's existing aluminum recycling business in Europe. The joint battery initiative between Panasonic, Hydro, and Equinor is progressing as planned with our market investigations, business case building, and site selection process for the potential Norwegian battery cell plant.
The local interest for hosting a plant has been very positive, and we are working with relevant government for this on firm conditions. One obstacle has occurred lately related to the rule of origin for Norwegian-made EV batteries created by the new trade agreement between the EU and U.K. following Brexit. We are pleased to note the strong support from the Norwegian government to seek solutions to this challenge. We have built an extensive pipeline across the battery value chain with two investments in operations and ambitions of NOK 2.5 billion-NOK 3 billion investments by 2025, returning a pro rata of NOK 600 million-NOK 700 million in kroner. We are evaluating several other opportunities along the battery value chain. Hydro is seen as a very attractive partner, and there's a good access to potential projects.
Let me move to our newest growth area, the hydrogen. Please turn to the next page, please. Hydrogen will play a key role in the energy mix towards 2050 and the global transition to carbon neutrality. Clean hydrogen produced from renewable sources enables industry, long-distance transport, and other hard-to-abate sectors to move away from fossil fuels. We see a substantial potential for industrial hydrogen consumption, which helps to reduce our CO2 emissions. By producing and offering clean hydrogen, which does not emit CO2 when used, we can enable Hydro and other industrial companies to succeed in the industry transition. We are now establishing a separate hydrogen company to take a leading role as a developer and operator in the hydrogen sector, switching from gas to hydrogen at several of our own sites, as well as developing and serving the external market.
Our new hydrogen business will leverage Hydro's large global footprint of industrial assets and Hydro's world leading position in sourcing renewable power. We have a large hydrogen potential in industrial heating in our own portfolio, equaling approximately 4 GW of hydrogen production long term. Switching from gas to hydrogen in Hydro's downstream and primary aluminum sites alone would cut 1 million tons of CO2 emissions. This would enable us to offer our customers aluminum with even lower CO2 footprint than today and contribute to our target of reducing Hydro's CO2 emission even further. To start with, we look at switching from gas to hydrogen at some of our aluminum plants in Norway and Europe. We believe the global efforts to decarbonize, attractive political support schemes, higher CO2 prices, and lower technology costs make this the right time to move into green hydrogen based on renewable power at attractive costs.
Establishing a separate hydrogen company will give the organization speed and flexibility around financing, resources, partnerships, and projects. We are evaluating an equity raise in the hydrogen company to support the growth agenda. We have set out to explore hydrogen potential based on our long-term captive demand with Hydro Rein as a potential vehicle to develop renewable power and the ability to leverage Hydro Energy market and system support, as well as Hydro's operational capabilities. With that, I would like to hand the word to you, Pål, to take us through the financials in more detail.
Thank you, Hilde. Good morning from my side as well. Hope you and yours are all keeping safe and well. Before we move into the details of the quarter, I would like to just make some comments on changes in our performance measures for 2021. We reviewed our key financial metrics used for performance follow-up and managing capital during 2020. The goals of the review were to achieve clear communication aligned with industry and peer practice. Also simplify where possible. Input from you, the key users of our reporting material, was highly prioritized in this process. This process resulted in a decision to focus on EBITDA and adjusted EBITDA as the main performance measures going forward, moving from EBIT and underlying EBIT.
We are moving from items excluded to adjusted items as this line also includes elements included in the results, such as currency elements from our strategic hedging contracts and from the embedded derivatives on our long-term energy sourcing contracts moving into Aluminium Metal, which are now being realized from 2021 and onwards. In addition, on the March 5th, 2021, we announced an agreement to sell our rolling business to KPS Capital Partners, and following the agreement, operating results for the rolling business are presented net of financial items and taxed as income or loss from discontinued operations and separated from Hydro's reported EBITDA and adjusted EBITDA in the first quarter reporting. Next slide, please. Let me then move over to the high-level result overview.
Hydro's adjusted EBITDA for the first quarter of 2021 was NOK 5.182 billion, compared with NOK 3.810 billion for the same quarter last year, an increase of NOK 1.4 billion. On the positive side, we see higher all-in metal prices, higher energy prices, volumes, and new contracts in energy, and improved margins and volumes in Extrusions, which all contributed positively to the results. In addition, we had negative currency effects on the strengthening NOK versus the dollar and additional maintenance-related costs in Bauxite & Alumina. Next slide, please. If we then take a look at the key financials for the quarter, the revenues are stable at around NOK 32 billion for the first quarter.
Adjusted EBITDA came in at NOK 5.2 billion, as explained on the previous slide. The largest adjustments to EBITDA of a total NOK 1.1 billion are related to unrealized losses on LME related contracts of NOK 1.2 billion. This is mainly related to our strategic hedging positions entered into over the latter quarters. This is offset by net foreign exchange gains and a positive gain on a listing of a small thermal storage company that we hold 9% in. In addition, we had around NOK 200 million adjusted from EBIT, driven by restructuring-related impairments in Extrusions and accelerated depreciation related to the announced closure of the Aluchemie carbon anode plant. Financial income for the quarter amounted to NOK 424 million related to positive currency effects on the embedded derivatives in the energy sourcing contract, as the NOK has strengthened compared to the euro, which is partly offset by interest expenses.
Our tax expense was NOK 776 million for the quarter, or about 29% of income before tax, in line with our long-term guidance of around 30%. Overall, this provides a net income from continuing operations of NOK 1.9 billion, up from NOK -1.7 billion the same quarter last year. Adjusted net income from continued operations was positive NOK 2.4 billion, up from NOK 0.8 billion in Q1 '20. Consequently, adjusted earnings per share from continuing operations was NOK 1.15 p er share, up from NOK 0.39 per share in Q1 2020. Let's move into the business area. Next slide, please. If we start with Bauxite & Alumina, then adjusted EBITDA decreased slightly from NOK 1.102 billion in Q1 2020 to NOK 999 million in Q1 2021. The quarter saw positive effects of a higher realized alumina price, currency effects of weaker BRL against the USD, and higher alumina sales.
These three categories in total impacting results around NOK 700 million. This was more than offset by higher raw material prices, impacting results around NOK 200 million, mainly related to fuel oil. In addition, the higher costs related to the ship unloader event in Q4 and higher sourcing cost for alumina impacted results in total of around NOK -600 million for the quarter. Despite high COVID contagion rates in Brazil and the ship unloader event, our preventive measures has resulted in improved production in the quarter for both Bauxite & Alumina, with Paragominas producing at 11.4 million tonnes annualized speed and Alunorte at 6.2 million tonnes annualized. In sum, all of these factors resulted in a higher implied alumina cost per tonne in Q1 2021 of $ 243, which is $17 above Q1 2020, while overall margins ended up at similar levels year-over-year.
Compared to the fourth quarter, we have seen a slight decrease in cost and a NOK 20 increase in margin. If we look into Q2, then Alunorte is expected to continue to operate at around nameplate capacity. We also expect costs associated with the craning repair to come down to around NOK 100 million for the quarter. This is more than offset by higher prices for fuel oil and also maintenance at Paragominas, reducing bauxite volumes and lifting maintenance costs. Next slide, please. If we then move further upstream to Aluminium Metal, then adjusted EBITDA increased from NOK 1.197 billion in Q1 2020 to NOK 1.754 billion in Q1 2021. We experienced a $235 higher realized LME and higher premiums and sale volume. In total, this contributed with a NOK 1.5 billion effect.
This was partly offset by weaker NOK against the dollar of around NOK 600 million and higher alumina, carbon, and power prices of around NOK 400 million. It is also worth mentioning that we have booked a positive NOK 120 million risk-adjusted CO2 compensation, which reflects two months of eligible sales volume. Although not all elements are approved by the relevant authorities at the end of March, based on the elements approved, we have concluded that estimates reflecting the uncertainty in final approved can be recognized. A full year of production is currently estimated to result in CO2 compensation of between NOK 700 million-NOK 1 billion. When it comes to the outlook for Q2, we have by the end of March, sold approximately 65% of our primary production forward at a price level of around $2,108 per tonne. This includes pricing from our strategic hedging program.
On the premium side, we have secured around 59% at around $333 per tonne, and we expect the premium level to rise to between $275 per tonne-$325 per tonne. We are currently seeing strong development in the market premium, which will translate into further increases in premium for the third and fourth quarter, given our current booking setup. Given the market prices for raw materials, we also expect smaller increases in raw materials for the second quarter, mainly carbon. This will partly be compensated by higher CO2 compensation, reflecting three and not two months for the second quarter. In addition, due to the continued ramp up at our Husnes Line D and also improvement in production at Husnes Line A, at Årdal and at Sunndal, we expect primary aluminum production to increase by around 20,000 tonnes in the coming quarter. Next slide, please.
For metal markets, the adjusted EBITDA ended up at NOK 78 million, down NOK 209 million from NOK 296 million in last quarter. The results decreased mainly due to lower realized sales premiums in recycling and negative currency and inventory valuation effects. If we exclude the currency and inventory valuation effect, the result for the quarter was NOK 161 million, which is up from NOK 119 million in Q1 2020, driven by stronger results in our commercial operations. Looking into the second quarter, we expect stronger results from our recyclers, also remember that as always, results from our commercial operations are by nature volatile. Next slide, please. If we then move downstream, adjusted EBITDA for Extrusions significantly increased from NOK 1.242 billion in Q1 2020 to NOK 1.744 billion in Q1 2021.
We reduced fixed costs significantly following the COVID outbreak, and we still keep these costs low as the markets improve, also supported by significant improvement work and the restructuring undertaken last year. The results were also positively impacted by higher volumes driven by strong demand, increased margins, and also lower variable costs. It is also good to see that Extrusions are now back above their long-term cost of capital on a 12-month rolling basis after a couple of years of being right below, and the continued improvements in the coming year should ensure that Extrusions continues generating economic value. Looking into the second quarter, we expect a continued strong demand and continuation of low fixed costs.
I will also repeat Hilde's earlier guidance in that we should see a strong second quarter as our volumes are expected to grow more than what market analysts are currently estimating for the market as a whole. Next slide, please. We end the business area review with energy, which delivers an adjusted EBITDA of NOK 841 million, increasing from NOK 505 million in the first quarter of 2020. The quarter saw a seasonally high production at higher prices due to below normal temperatures and low wind power output compared to the same quarter last year prices of NOK 422 today. However, uncertainty is still large and will depend on the hydrological balance going forward and when the spring thaw takes place. Next slide, please. We now move from the business areas to the development in net debt. Overall, our net debt position increased by NOK 1.2 billion.
We started Q1 with NOK 7.8 billion in debt. We had an adjusted EBITDA of NOK 5.2 billion. Net operating capital increased by NOK 2.4 billion, driven by the normal seasonal increase, but also strong customer demand in addition to increasing prices. Other operating cash flow adjustments amounted to NOK 2.3 billion, mainly driven by tax payments, bonus payments, interest expenses, as well as also negative collateral effects from our hedging positions given the current very strong pricing environment. As a result, we generated a net cash flow from operations of + NOK 0.5 billion in Q1. We had investments coming in at NOK 1.3 billion, and then we had other effects of NOK 0.7 billion, which are mainly driven by positive currency effects on debt. Finally, net cash used in discontinued operations amounted to NOK -1.1 billion, impacted by increasing net operating capital in our rolling unit.
At the end of the quarter, we ended with NOK 9 billion in net debt. We also comment on adjusted net debt. Remember that the adjusted net debt definition reflects Hydro debt and liabilities only and does not include the previous adjustment for Hydro's share of net debt in equity accounted investment. We look at adjusted net debt at the end of the first quarter 2021. It decreased by around NOK 10.3 billion compared to Q4 2020. I have just explained NOK 1.2 billion through the net debt increase. Net pension liabilities decreased by NOK 10 billion, mainly due to reclassification of liabilities in rolling as liabilities in the disposal groups. Higher discount rates in Norway, as well as positive returns from pension plan assets in Norway, also contributed positively. Other liabilities decreased by NOK 1.2 billion, mainly due to reclassifications of asset retirement and restructuring liabilities in rolling.
With that, the total adjusted net debt at the end of the first quarter of 2021 amounted to NOK 12.3 billion, which is a reduction of 45% compared to Q4 2020 and 63% compared to the high level seen at the end of Q1 2020. Next slide, please. Let me end with an update on our strategic hedging program. Since the last quarterly presentation, Bauxite & Alumina has extended the USD BRL hedge to cover 2023 as well, resulting in a 30% hedge for the years 2021 to 2023. In addition, another 100,000 tons per year of aluminum hedges have been placed for the years 2022, 2023 at price levels seen in the middle of April. The total aluminum hedge amounts to 250,000 tons for 2021 and 350,000 tons for 2022 and 2023.
Raw material costs have been partly secured using financial derivatives or fixed pricing on physical raw material contracts. In addition, an amount of dollar NOK hedges are in place. With that, I give the word back to you, Hilde. Next slide, please.
Thank you, Pål. Let's conclude today with our key priorities going forward. Health and safety will always be our top priority, both for our employees and the communities where we operate. We will continue to capture opportunities from strong markets to grow both volumes and margins. The improvement program is an important enabler to deliver on our strategic direction and will continue with full force. Our cost program and commercial ambitions have strong momentum and is well anchored in the organization. We will execute on the 2025 strategy to strengthen our position in low carbon aluminum and grow in recycling, and expand and diversify in new energy areas, including renewable growth, batteries, and hydrogen. Finally, we will reaffirm our ambitious targets for climate and environment as sustainability is one of our competitive advantages and a key enabler for successfully delivering on our 2025 strategy.
Thank you, Hilde. Operator, we are ready for questions.
Thank you. Ladies and gentlemen, if you would like to ask a question, please signal by pressing star one on your telephone keypad. If you're using a speakerphone, please make sure your mute function is turned off to allow your signal to reach our equipment. A voice prompt on your phone line will indicate when your line is open. Please state your name before posing your question. Once again, that is star one for your questions today. We take our first question today. Please go ahead, caller. Your line is now open.
Good morning. It's Liam Fitzpatrick from Deutsche Bank. First question or two just on your new growth areas. I guess just a high-level question, trying to understand your thinking. There's a lot to absorb in this release, and there's now three or four different growth avenues that you're considering. The question is, do you think you're taking on too much given that the last two years has really been about cutting costs and simplifying the business? Interested in your thoughts on that. More specifically on hydrogen, can you give any sort of details on how much equity ownership you want to keep of this new hydrogen company that you're setting up? Is the plan to keep over 50% ownership?
Can you give any kind of feel for the level of investments we could see if you do proceed with some of the projects that you're considering over the next one to two years? One final sort of operational base one, if I can, just on the Extrusions business, which has had a very strong quarter. How much of this uplift that we're seeing in Q1 and that you're guiding to Q2 is driven by lower costs, which will ultimately come back once travel restrictions and travel resumes? Thank you.
If I can start on your comment to the growth areas and your question, is this too much? That is obviously a question that we ask ourselves. Here, that is one of the reasons why we have been very carefully in establishing separate entities, ring-fencing the initiatives, as well as realizing that the new entities with the new entities has a lot to learn from each other. We also see that these new initiatives also create a lot of excitement in the rest of the organization, while when we see that, as you said, we have been in a cost-focused mode for many years. We see that this creates opportunities for our people to move in the company.
Yes, it's a lot on the agenda, but I believe that with the way we have set it up in separate organizational entities with mobilizing the people from our own organization, but also coming from outside because we realize that in some areas we also need expertise from outside. I feel confident that we have the right focus and, let's say, the good basis for developing these renewable energy areas. Perhaps you can comment on the equity. When it comes to the hydrogen area, that is the newest, and there is still a lot that we need to mature in terms of how we will set this up. We will organize it as a separate entity. We will bring in partners, but at this stage, it's still early days in, let's say, the financing of it.
When it comes to the extrusion and the cost situation, yes, extrusion has done a fantastic job when it comes to working on their cost base, both during 2019 and 2020. Now also focusing on to preserve as much as possible of what has been gained through the SG&A initiatives, also obviously getting effect of the restructuring that was done in the two last years. We are cautiously optimistic in the sense of preserving as much of the gain that has been made, then also continue to focus on an efficient cost base of the sites.
Just to supplement Hilde on the equity ownership and capital expenditure side for both Rein and the hydrogen ventures, we are targeting majority the ownership. For both of these entities, we are working to set up a model which limits the cash pool from the Hydro company. Both of these ventures, although given the ownership side, CapEx, et cetera, will be consolidated into Hydro's balance for what is done on a top level, not what is done in special purpose vehicles. We still aim to do it through a more or less cash neutral set up for Hydro. The new growth initiatives, which will have a cash impact on Hydro in the short to medium term, is the batteries or battery initiative.
Okay, got it. Thank you.
Thank you. We now move on to our next questioner. Please go ahead, caller, your line is now open.
Yep, it's Jason Fairclough at Bank of America. Thanks for the presentation. Pål, just up front, I wanted to thank you for your revised approach on the reporting metrics. This is going to be very helpful for comparability with peers. Thanks for that. Look, two quick questions from me. First, in terms of the market, China is exporting less aluminium by the looks of things, so we're going to have tight markets outside China. Could you talk about what price would see you consider adding primary supply, or what is the incentive price for you to build a new smelter? Then second, just in terms of the brands, the low carbon and the recycling. Volumes are picking up, but can you talk about whether this is actually a premium product yet?
Thanks, Jason. I can start on the upstream side. At the moment, we are not discussing increasing primary aluminum capacity within our portfolio. That being said, the integrated margin level for the Norwegian operations is at a level which would make smelter investment more robust than they have been for a very long period of time. At the moment, we are running a sustained and improved focus on our upstream business areas, also driven by the fact that we've seen investment costs in other parts of the world being much lower than in the western part of the world. We will continue to follow development and see how it plays out, but there's not a price level that triggers us to make investments in the short term. On the low carbon products.
Yeah, I can comment on that. Well, the low-carbon products are still in the early phase, and what we have been doing is that we have targeted market segments that appreciate the low-carbon, such as the building system, and with the example that I gave from the Google office. Here we see a willingness to pay a premium. This is how we have to work to expand the interest and for the awareness of how the metal is produced and with the carbon footprint. This is an ongoing work that we have to do, and we see that there is a trend out there, and these products get more and more traction.
Yep. Thanks very much, both. Could I just have a follow-up? In terms of adding volumes, can you just remind us, do you have any opportunities to increase primary metal production? Is there mothballed capacity, or do you have low capital intensity brownfield expansion potential at any of the smelters?
Right now we are in the ramping up of the Husnes smelter in Norway. It's a line that was closed in the financial crisis back then, and which will be up in full capacity during the summer this year. Other than that, we have some capacity out in Sravanpur, but that's just a minor portion. At this point, we are almost at operating at full capacity in the smelter portfolio.
Additions will be more related to creep initiatives, getting more out of existing capacity on top of what Hilde mentioned.
Recycling.
Recycling.
Okay. Thanks very much, folks. Appreciate it.
Thank you. We now move on to our next questioner. Please go ahead, caller. Your line is now open.
Hello, good morning. This is Ioannis Masvoulas from Morgan Stanley. Thanks very much for the presentation today. The first question from my side, just following up on Jason Fairclough's question around potential for aluminum growth within the portfolio. Sounds like a lot of it is going to come by recycling. It's fair to say that over the past six months you have been focusing a lot on diversifying away from primary aluminum into all the green growth areas you have been talking about today. If we were to fast-forward to, let's say 2030, could you share with us your vision on how the earnings contribution from your B&A and smelting activities could change over that time frame relative to the 40%-50% EBITDA share we've seen in the past years? I'll stop here for the first question.
Well, we have shown some potential in terms of both EBITDA and growth when it comes to both renewable energy batteries as well as now the new hydrogen. Still the low carbon aluminum part will constitute a large part of the company, and that is why we have these two pillars in the strategy to continue to grow on the low carbon, with particularly growing in recycling, and then to develop these new opportunities with the potential that we have illustrated.
Okay, great. Thank you very much. Just a couple more from my side. Just on the hedging side, especially for primary metal, I guess that gives you more cash flow visibility as you look to reallocate capital in some of the growth areas. Could you remind us what's the upper range of percentage of volume that you are willing to hedge over the next few years? Separately, just on Bauxite & Alumina, looks like the crane damage continues to pose some additional costs into Q2. Do you expect further costs into the second half? How likely is insurance compensation given the size of the overall costs we've seen since Q4 last year?
Thank you, Ioannis. I can answer those questions. If we start with the last one on the crane incident, this impacts the quarter a bit more than what we had expected. This is also driven by the fact that the solution to reduce costs has taken somewhat longer to get in than what we planned for. Into Q2, we will be expecting another NOK 100 million or so, but on a total level, quite a reduction from what we saw in the first quarter. In Q3 and Q4, we will have smaller figures, probably around half of that again. It's starting to become less significant. What will change the situation is getting in place a new solution, because we're running more a temporary solution today.
We're still evaluating which process to go with there, thinking a bit longer term also. Insurance compensation is difficult to comment on at current stage, and I don't want to set any expectations in either directions, but it is handled as an insurance case. We will revert when we have some more clarity. If I start with the hedging question, we are reaching the ceiling for what we believe is a targeted level for the integrated margin hedge. We have said we're moving up to 20%-25%. That's where we believe we have a good balance between protecting and making the company somewhat more robust in the low-case scenario, while still leaving the majority of the portfolio open for positive price movement.
Great. Thank you very much.
Thank you. We now move on to our next questioner. Please go ahead.
Yeah, morning. It's Amos Fletcher from Barclays here. I just had a couple of questions. The first one was around the net debt level. I just wanted to get a feeling for do you have in your minds a net debt level below which you would seek to return surplus cash flow, sort of over and above the dividend policy? The second question is just on batteries. Just looking at your projections for potential CapEx and potential EBITDA, could you give us some sort of detail on where that EBITDA is coming from and sort of, I guess, a little bit of a sort of build up behind the numbers that you've given there in terms of NOK 600 million-NOK 700 million pro rata by 2025? Thanks.
Yes. I can start here with the net debt level. Basically, we are approaching a level which is well within our targeted levels that we updated at Investor Day in 2020. We don't have a trigger which will result in the payout of extraordinary dividend or similar. As we move forward now with the strategic process, allocating capital to the different areas, evaluating the possibilities that we see going forward, we will make an evaluation towards the dividend process at the end of next year, or our board will do so to set the level for 2021 as a whole. There we need to ensure that there is a good balance between strength of balance sheet, available capital for investments, and return to shareholders.
Given the current earnings environment and our policy of a minimum of 50% over the cycle, there is of course, a good room for a significant increase in dividend into next year. The second question was on.
Batteries
A ll of these new growth areas that we operate in, we are working in the mode where we have quite a large pipeline of alternatives. We're maturing more ambitions than we believe we will end up with at the end of the day to ensure that a certain value creation is generated. Splitting it up per contributor is a bit difficult because some might fall out in some time, some might progress, some might be larger than what we expect currently. The overall ambition has a long pipeline, which allows for some flexibility in which projects we pursue. If you look at the 2025 ambition of two and a half to three billion of investments delivering an EBITA of between NOK 600 million and NOK 700 million, then the list is much longer than these levels.
On the current initiatives which we have visualized, of course, the largest contributors in this setup as we see it today is the joint venture we have with Panasonic and Equinor. Also, Corvus is of a growing scale. The Hydrovolt initiative has quite some potential if we ramp up further than what we have in the current plan. These three are of course heavy contributors. We have four or five initiatives or more that are not covered by this overview. If some of these investments slow a bit down and we see that the business case doesn't stand up, we might reprioritize a bit within the portfolio. We will keep you updated on a semiannual basis through these strategic reviews on which projects are progressing well or not. So far, Corvus Energy, we see development, as Hilde mentioned. Hydrovolt is going as planned.
We have some obstacles now in the joint venture with respect to rules of origin, but we will see if we are able to cater for that risk over the coming year or not.
Okay, thanks. I guess that pro rata EBITDA, is that based on a target return on capital employed or is there more to it than that, as it were?
Yeah, of course, all of these have a targeted return on capital employed, and we screen based on the best returning candidates. The same approach we run in recycling and the Hydro Rein venture and hydro gen also.
Okay, perfect. Thank you.
Thank you. We now move on to our next questioner. Please go ahead, caller.
Hi, thanks. Dan Major from UBS. First question, follow-up from Jason slightly, just to clarify on the numbers around the green premiums. If I look at page 11, you allocate 20% of the NOK 1.5 billion commercial ambition to new products, including greener brands. Is it fair to assume that that is effectively capturing your estimate of the financial upside from greener brands? Is that what we should read from that chart?
No, because that only covers the greener premiums that Aluminium Metal receives on their product. Then there might be an additional effect when extrusions sell them further out in the market. As you know, between these two business areas, there's less differentiation possibilities in primary than there is in extrusion, as this is more project-based. As Hilde mentioned earlier, we are targeting premiums on the majority of our volumes. For some of them, we will also target volumetric increases. As this market moves forward, you will see that gradually reflected to a larger extent in our realized premiums overview at the end of the day. Of course, at the end of the day, this is also a negotiation on a customer-by-customer basis. As such, we don't want to disclose the exact details of these premium components.
Okay, thanks. The next question is on the indirect carbon compensation that you are beginning to accrue through the P&L. When do you expect to see that reflected in the cash flow statement?
I guess that is more towards 2022. The setup is currently so that you get paid in the year after you produce the material and consume the carbon, in a way.
Okay. Sorry, it's an accounting question, that, I guess, will be reflected, you build a receivable on the balance sheet, then because you've owed that. Is that correct?
Yeah. We record it now, and then we reverse it next year, and then you get the cash flow in.
It would be about NOK 700 million-NOK 1 billion of cash flow that you'd receive as a one-off payment in early 2022, I guess.
That would come in in 2022, yes.
Okay, great. Thanks. Just final question on Extruded. You obviously mentioned around growth rates relative to market expectations, but on a year-on-year basis, where we're talking about obviously quite a skewed base. If we just purely looked sequentially relative to Q1, is it fair to assume you'd see higher volumes, higher EBITDA?
Yeah, that's a good question. I understand the challenging using the second quarter last year as a baseline. Numbers become so big with respect to volume growth. I just want to stress that we expect higher volume growth than what the market is seeing. This 36% and 30%, which CRU refers to, we will most likely end up a bit above that. Then I think your second question is very relevant. If you look at historical development and seasonality in our extrusion operations, we often come in higher in the second quarter than the first quarter. As the market is playing out now with the more normalization, et cetera, we expect to see that trend also in the current year.
The only risk element I would like to flag in that context, which could result in a different picture, is if we see some challenges on the supply side. As you know, markets are very tight currently, and supply chains are tight. If we get any form of global hiccup, which happens from time to time in the aluminum industry, then that could impact what we get of earnings in second quarter. If things go as planned, we should expect to see a seasonally stronger second quarter than first quarter.
Excellent. Thanks a lot.
Thank you. We now move on to our next questioner. Please go ahead caller, your line is now open. Please go ahead caller your line is open please ensure youare not muted.
Apologies. It's Liam Fitzpatrick again from Deutsche Bank. Two very quick questions, hopefully. Just on premiums, the Q2 guide, given what we're seeing in terms of regional premiums, looks low. Can you just give a bit of color there? Should we expect the premiums will move higher again as we look into Q3? Then just coming back to the CO2 point. You haven't changed the guidance of up to a NOK 1 billion EBIT uplift, but since you provided that guidance, the CO2 price has gone up by over 50%, my understanding was that there was a positive direct correlation there. Can you just give a bit of color in terms of how that's impacted your guidance?
Yeah. On the premium side, it is true we expect higher premiums in the third and fourth quarter if market remains where they are now, and most likely in most situations as we have already booked quite a lot into the third and fourth quarter. There is quite a lag on the realized premiums. There's some full year contracts, there's some shorter contracts, and then you get that total situation of three to four months or so. We expect an increase in Q2, further in Q3, further in Q4, and if spot prices remain where they are now, you should see stronger premiums into next year. Also in an historical context, the billet premiums are very high now, approaching $900, for example, for extrusion ingot. The second question was.
CO2
CO2, yeah. Within that range is also development in the CO2 price, and we are at current price levels. You're probably towards the higher end of that range than the lower end of that range.
Okay. Thank you.
Thank you. We now take our next questioner. Please go ahead, caller. Your line is now open.
Good morning. Jatinder Goel from Exane BNP Paribas. Just a question on wind, solar, and hydrogen. You've got a big hydropower portfolio as well, but its external exposure is limited because most of it gets used internally. Just to understand, on your wind, solar, and hydrogen, because you have this opportunity to electrify in Brazil and also switch from gas to hydrogen in many of your operations as you indicated, what would be the eventual external exposure of wind, solar, and hydrogen once you get to your stated ambition? How much will be used internally versus externally of your attributable share from these two businesses? Thank you.
Yeah. I think it's still a bit early days, Jatinder, but to give some color on the total landscape, if you start with bauxite or Brazil and the repowering efforts that we're running there, then for the smelter and the bauxite and aluminum operations, they both rely on external power as is the case today. As we progress on developing solar and wind projects down there, then a larger share will be based on a percentage of equity production, depending a bit on, one, our ownership in the topco, and two, the ownership of the topco to the special purpose vehicle, and then how much of the external sourcing these plants end up consuming. You have a similar situation across the Nordics and through the hydrogen portfolio.
We don't have the full details in place there yet as we are developing on a portfolio basis, negotiating contracts, negotiating ownerships. We will have to update that as the pipeline becomes more concrete and we have a better view on what ownership we will have in the different operations. It will not, of course, be 100% or even a percentage reflecting an ownership in these topcos because this will be built up in special purpose vehicles where the topco also has a smaller ownership stake than 100%.
Sure. Thanks, Pål. That is very helpful. Just to get the thinking clearly, is the idea to go into these businesses to make more money for the businesses by going and serving the outside world, or is it more to home improve and make your own operations exposed to greener energy over the medium term?
I think the internal demand creates substance to the project, that we can build capability based on the internal demand. While we are doing that, we can also approach the external market. It is both.
Okay. Thanks, Hilde. Very clear.
Thank you. At this stage, we have no further questions in the queue.
Thank you. Thank you, operator. I would just wish to thank you all for joining our call today, and please don't hesitate to call us or send us an email in investor relations if you have further questions. Thank you and have a good day.
