Good morning, ladies and gentlemen, and welcome to the Ceres Power plc interim results investor presentation. Throughout today's recorded meeting, attendees will be in listen-only mode. Questions are encouraged. They can be submitted at any time just using the Q&A tab situated on the right-hand corner of the screen. Please just simply type in your questions at any time and press send. For those in the room, we will provide you a microphone for the Q&A. Before we begin, we would like to submit the following poll. I am sure the company will be most grateful for your participation. I would now like to hand over to Phil Caldwell, CEO. Phil, good morning.
Good morning, everybody, and thank you for joining myself and Stuart for the interim results up until June 30 this year. I am very pleased to update you on quite significant progress I think the company has been making. Just to remind you, the growth story of Ceres is built upon three strategic pillars. Signing new manufacturing licensees. That is all about growing market share and establishing this technology as the industry standard.
Once we have those partners, accelerating them to market and scale-up and getting into the market is obviously increasingly important. Then obviously, as a technology business, we have the single stack technology platform, which is Ceres Endura, which we launched earlier this year, and that is really the platform upon which our partners are scaling and making significant investments as we go today. The first half of the year, we have made what I would say considerable progress.
I am very happy with where we are on the pipeline. We have continued to grow that in all regions, and we reiterate our guidance with main confidence that we are in a good position to sign a new licensee this year. Once we have those partners, we have obviously focused on our existing partnerships as well, and there is quite a lot of activity going on with those partners.
With Doosan in South Korea, they signed their first export order, which is around GBP 60 million supply stacks to Reverion in Germany. Delta and Taiwan are continuing to put in the first initial production and have also announced plans for a new facility in Guanyin District, in Taiwan. In China, Weichai are going extremely quickly, and they are targeting first production later this year, early next year, and have announced 200 MW by the end of the year after, so within two years. Incredibly fast.
On the hydrogen side, Japan with Denso. Denso received GBP 165 million in government support, so we are continuing to make progress on the hydrogen side, but our near-term priority is really on the power system side. Earlier this year, we also signed a partnership with Centrica here in the U.K. That is more of a channel partnership where we aim to bring in technology into regions like the U.K. and Europe from our manufacturing licensees. I am pleased to say Centrica is already starting to develop their own relationships with our supply chain as well, so that is incredibly important for us as we match up the demand side with the supply side that we are building out in this ecosystem. I mentioned the single stack technology platform, Ceres Endura. That is our flagship solid oxide stack platform.
That's the culmination of many years of not just research, but manufacturing and engineering, and it's really the building block now as people scale factories. We're not going to be changing that every year. It's all going to be about improving lifetime and cost and CapEx of factories as people scale. That gives them the confidence, and we think that is the leading stack platform out there. On top of that, or underpinning that, should I say, we've reinforced the business. In the first half, we took the opportunity to continue with the business transformation, which we undertook last year, which is built around these three pillars of focus, and that's continuing to deliver an optimal cost base, I think. Following years of significant investment, we're now at that execution stage, and Stuart will talk more about the financial performance in just a moment.
We also reinforced the balance sheet with just over GBP 100 million in an oversubscribed equity issuance earlier this year. That's really important for the business because as our partners are making significant investments in scaling, it's important that they realize that we're here in a very strong position to support them as the technology provider of choice. Just a very quick reminder of our strategy. We are 25 years old this year. We believe we have world-leading technology on solid oxide. That's transferred to partners now through the Ceres Endura stack platform, which we launched earlier this year. It's not just a stack platform. We also provide the factory blueprints and also have relationships now with line builders, factory builders who can help our partners get into market quicker and easier. That technology platform, the Ceres Endura, has two functions. Running in one direction, we can generate power.
Running in the other direction, we can generate hydrogen or synthetic fuels, as is the case with Reverion. The urgency right now is on the power side, and we have Doosan in South Korea, Weichai in China, Delta in Taiwan, all either in production or imminently coming into production and scaling. On the hydrogen side, we've been working for a number of years with Shell as a channel partner, but our licensee partners are Denso, who are making good progress, and Delta also has the dual license as well. We work with Thermax as a systems integrator in India. So one platform, intentions, global factories, and partnerships. Just want to talk a little bit about the demand for power. I think many of you probably are seeing this or are familiar with this, but there's two things going on here.
One is the demand for power has never been greater, and that's got pretty acute because conventional power generation equipment is in short supply. If you want to buy a gas turbine, it's five to seven years lead time. If you think about nuclear, it's into the next decade. If you think about waiting for a grid connection, not just in the U.K., but in many countries now, it's at least five years and up to a decade. Now, the time to power creates a window of opportunity for us. I believe that we have about a five-year window to get into this market, establish this technology, and get down the cost curves and scale the supply chain. Part of that is time to market. It's all about time to market. Our first factory that we did with Doosan took us around four years, around the COVID time.
Current factories that have been built, around three years. The factories that we currently have now, the last factories we signed with the likes of Weichai, are on track for about two years or less. That's because we've standardized the Ceres Endura, we've built factories several times over, and we've actually now got partners who can actually, when we sell a license, we can actually bring into view and help people lay down production pretty quickly. So two things going on. Time to power is acute, and wait for conventional power generation has got longer, and our ability to get people into the market is getting faster. Why do we think that the Ceres Endura platform can win in the power market? Well, I've just mentioned the first factor, which is time to power, and I've mentioned this window.
However, it only works if this technology is cost competitive, and right now we are cost competitive with conventional power generation, there or thereabouts. Now, with time, there's going to be more supply, I think, of things like turbines, recips, et cetera, and they'll start to come cheaper again. But I think where we are with solid oxide is we're only at the beginning of that scale-up journey, and the costs are going to come down with scale, with supply chain, with localization. So we're cost competitive now, and I think in the future, if you look at the attributes of this technology, it's predominantly steel. The rare earths we use are commonly available. We're using equipment that's come out of standard chip manufacture, PV manufacturing.
It can scale rapidly, and there's no reason why we can't get down these cost curves, particularly with the manufacturing partners that we've already signed. But then I think there's another story to this, which is what gives solid oxide the right to win in the long term? If you actually look at this from the other factors that are coming on in terms of power generation, the first thing is permitting. Just because you can build power doesn't mean you should build power or you have the right to build power. You're probably seeing it in the news. There's a lot of resistance to new data centers, for example, being built, particularly in the U.S. We're seeing power generation, what we call behind the meter, on-site power generation.
In some cases, contracts that were won by conventional power generation, like turbines, like recips, actually now being flipped over towards solid oxide. Why is that? Well, first thing is almost zero water usage, which is becoming critical in many regions, as we've seen this summer. Things like lower carbon to zero carbon when you combine it with carbon capture. No combustion means air quality. So there's no SOx, no NOx. It's virtually silent, which means you can put it in buildings, you can locate it close to urban centers, et cetera. Because it's behind the meter, there shouldn't be an impact on local power prices as well. So actually, this technology is a better technology from a sustainability point of view, and that's becoming more of an issue with permitting.
If you have a technology that can be delivered in the right timescale because it's modular and coming out of factories, it's cost competitive and aids permitting, solid oxide becomes a permanent part of that energy mix. It's not just a passing thing because we can't get conventional power generation. The other thing that's interesting is when we think about conventional power generation, it's AC based, it's alternating current. That's because it was developed in the last century for the economy we had then. If you look at our economy now, it's more computing, it's AI, it's electric vehicles. A lot of that infrastructure is DC based. We're seeing companies like NVIDIA pushing 800 V DC architecture. The good thing about fuel cells is they're DC native. That means they actually generate DC power.
That means that you can, first of all, they're more efficient, so you can save about 5%, is NVIDIA's view, in terms of the efficiency of going from AC to DC in a data center by being DC direct. It's high voltage, lower current, which means you're saving on things like copper. You're eliminating things like switch gear, transformers, et cetera. You can also get more power into the rack, which is going to be a key feature going forwards. As well as the permitting, the 800 V DC compatibility is going to become more and more of a potential requirement from about 2028, 2029. The way I see the whole thing is the window's opened up now. First buying criteria is always going to be cost and time to power. But then permitting comes along, and then also future-proofing for 800 V DC.
The Ceres Endura platform meets all of those requirements. This is Ceres' view of the market. We haven't changed this. We think it's about a 22-GW opportunity by the end of the decade. There's a lot of interest, obviously, right now in things like data centers, but that's about 50% of the market. We're also seeing a lot of interest in industrial applications, commercial buildings, and also shipping in the future. Regionally, obviously, the U.S. is the biggest market right now, but when you look at the rest of Asia, that's 50% of the market, Europe, et cetera. We see this as a global market. This is not unique to one particular region. Just going on now to what progress our partners are making. I mentioned earlier Doosan are making progress with their first contract for stack supply, with Reverion in Germany.
Reverion's an interesting company, because they have a truly reversible system using our technology, so they can generate power in one direction. When they don't need that power, they can actually generate synthetic methane in the other direction, so you have something that can arbitrage, if you like, and work on both sides of the energy mix. It's an important milestone for Doosan because it's their first export contract for SOFC. I mentioned Delta. The first production we're busy with right now in Tainan. That's a 2026 production facility. They have announced this year a brand-new facility in Guanyin in the north, which will house the scale-up, the mass manufacture of the solid oxide as well. Delta is obviously a key customer for us. Very big already in the ecosystem of data centers, and has the strength and the ability to scale fast.
We signed the partnership with Centrica earlier this year. That is all about bringing in this technology into markets where we have got the right kind of, first of all, spark spread, in terms of the opportunity for localized power generation, and also the need, and we have that in the U.K. in terms of the time for grid connections, et cetera. There is a lot more detail on this.
We published a joint white paper with Centrica just last week, and that has really got a lot of interest, particularly for end users for Centrica as well. That is also well worth looking at. It is not just about us. Our role here is to facilitate the ecosystem, so we have introduced Centrica to all of our partners. Centrica signed the first agreement with Delta, and that is really targeting data centers and other energy-intensive industries in the U.K. and Europe as well.
Weichai are going fast. We have been working with Weichai for a long time on system. They have not launched their new system yet, but it is pretty impressive, and they are looking to sell that through a subsidiary, Baudouin, in Europe at 600 kilowatt SOFC systems. At some stage, I hope later this year, this will be launched and announced. They have a lot of experience on the system side, and obviously now they are scaling up on the stack production side as well. That is on the power generation side. I want to also just reference our progress on hydrogen. I mentioned Denso. They have continued to develop the SOEC technology. They have had big government backing in Japan. That is continuing. We are very happy with progress there. Our partnership with Shell on the demonstrator continues to exceed expectations.
We are looking at now the next version of that, which is the pressurized SOEC, which we are doing in combination with Shell, but also looking to test that in India with Thermax, our EPC partnership there. I think that what we are seeing on the hydrogen side is obviously India is a big market for the hydrogen side, but we are also starting to see growing interest in China as well. So we continue to develop this technology because we are starting to see some demand for the SOEC. What do we think this market looks like? About 38 GW, but that is a 2035 number. I think the easy way to think about this is near term, between now and 2030, we think this is a power generation market.
If you are scaling Ceres Endura and you have the production, you are positioning yourself, I think, for the hydrogen market which follows end of this decade and into the next decade. So I think it is an important future value creation for us, and our positioning is good because all the work we are doing on the stack in terms of power generation, scale-up, supply chain, et cetera, it is the same stack technology that services the hydrogen market in the future as well.
As I mentioned at the beginning, it is all about becoming the industry standard for solid oxide. So that is building out this ecosystem. We have the four manufacturing partners we talked about already, and the systems and channel partners in terms of Centrica, Thermax, and Shell. So that is a brief overview of where we are strategically. I am very happy with the progress to date.
I will hand you over to Stuart to talk you through the financials.
Thank you, Phil. Phil has given us a bit of a briefing on where the market is and where we are in the market with our partners. I am just going to give you a little view of how that translates into numbers and how things are going back in Horsham and Redhill, where we are making some progress internally in transforming ourselves into a commercially focused company. On the financial review, our guidance for the year was that we had contracted revenues of GBP 45 million. You can see that we have achieved around about half of that in the first half, which is, I think, good progress. I have got a slide on the execution here. Obviously, the gross margin is going to be high. The mix is around licensing revenues, in the first half, and we will maintain that high margin.
The loss you can see has come down on a comparable revenue basis from the prior year based on all the work we have done in terms of rationalizing our cost base to give us more focus on the commercials. Again, you can see that in the R&D cost as well. We believe that this is now an optimized level of R&D we are spending. As Phil said, all this work crystallized into the Ceres Endura stack we launched in the first half of the year. We believe we have got the right people in the right places in our business to both deliver the next raft of lifetime and cost innovations in SOFC and SOEC, and also to get our message out into the marketplace correctly.
We did do a fundraise in the first half, but as Phil said, it is important given who we speak to in terms of the ecosystem, some of the biggest companies in the world, that they have got surety that we are going to be around to be their R&D engine for the next 20 years. This is a 20-year investment they are making in their factories, hopefully accessing both of the markets Phil has taken us through. That leaves us with a strong cash position. That is really, really positive for us. On the cash outflow, that is normalized, obviously, without the fundraise in it. But we have got a lumpy cash inflow and outflow given some of the big amounts that swing in and out of our bank balance, given some of the billing we do. We are pretty confident now.
We've got the right financial structure, the right cap table, to make the sort of progress that we're looking for. Just on this revenue and gross profit, I want to just highlight here that this is about execution. When we made the changes and kicked off our transformation at the end of last year, we wanted to be sure that we could still deliver for our partners. I think this is a story of delivery from our teams. I'm very proud of our teams having delivered half of the contracted revenue in the first half. Very confident we can deliver the contracted revenue in the second half. That really is a testament to a team that's going through embracing this transformation and continuing to deliver for our customers. A bit on the transformation.
It started at Q4 2025, and it's going to finish sometime this year. Continual improvement will always be there, but in terms of our transformation programs, we've really done a lot of work. The team can be very proud of themselves. We've got 350 to 370 people back in Redhill and Horsham who are doing a great job. We believe we've transformed the company into this commercially focused company. I think that reads through to the pipeline health that our chief commercial officer spoke about at the Capital Markets Day. We've launched Ceres Endura, which we did at the Capital Markets Day, too, and that's really the crystallization of a ton of hard work from the team.
Now we're very focused on this is our product to the market, making these lifetime and cost improvements, which we're very confident we can do to make this business case even more compelling for our existing and potential new partners. We've enhanced our commercial capabilities, done a lot of cultural work on being very partner centric, and we've also reduced cost while we're there. We believe now we've got an optimized cost base. We can make various investments from this point to enable us to bring this technology to the widest market we can. The cost base, you can see it's coming down significantly, or it's come down significantly, and now this is the base which we see we can make these specified strategic investments from. But we're going to be very, very prudent.
We've got the right people in the right place doing the right things now. We're going to be pretty prudent with that cash. But we do see now the opportunity to make some investments in scale-up for our partners. This is a technology now that's going from pilot scale to commercial scale. When we say commercial scale, this is very large commercial scale. We need to ensure that we are acting both on the demand side, as Phil laid out with Centrica, and on the supply side through supply chain management to make sure that our partners can move very, very quickly to gigawatt scale, because ultimately, this is all about royalties for us. The cash flow, you can see it's obviously coming down. It's dependent on signing new customers.
But we are definitely trending in the right direction here, and we reiterate that we have got a strong pipeline, and with one partnership on a cadence every 12 months, we will be more or less break even from a profitability and a cash perspective. That is the situation we find ourselves in now. So we have optimized the cost base for that purpose and to deliver world-class R&D, which we believe we can do, and put ourselves in the strongest position to be around for the longest time for our partners. With that, I will hand back to Phil.
Thanks, Stuart. Yeah. So just to close out, really. We think we are in a very healthy position now to take full advantage of this opportunity that we see ahead of us. That power demand is not going away. It is accelerating, and time to power is now the defining constraint, and it will be for the next five years. That is driving more and more interest for this technology. And this technology is now, I think, going from being something that was a new technology to something that people now start to understand and actually becomes part of that, a real option for power generation for behind the meter. We have built the Ceres Endura platform, and that is really designed for scale. And as we said, after many years of R&D, we are now in that scale-up phase.
So that Ceres Endura platform is not going to significantly change year on year, but it is going to have the continuous focus of cost, lifetime performance from our technology team in Ceres. And really our aim is to establish this as the global standard. And the way we do that is more partners scaling on the Ceres Endura platform. And that is the strategy we have, and we are very happy with the progress we are making to date. So thank you for your attention this morning, and we are happy to take questions.
That is great, Phil. Stuart, thank you very much indeed for updating investors. Ladies and gentlemen, for those online, if you continue to submit your questions just using the Q&A tab situated on the right-hand side. Before we take those online questions, perhaps I could just invite questions from the room. I will pass you the microphone, and then we will move on. Thank you.
Thanks, guys. Alex here from Berenberg. Just a question on kind of the current pipeline of partners that you are talking to. Could you maybe give a bit more color on what that looks like, how live discussions are going? You mentioned some reallocation of resources towards kind of better customer engagement. A bit more color on how you can do that would be great.
Yes, I will say what I can.
Yeah.
The pipeline has grown significantly and continues to grow. That is in all regions. We have engagements in the U.S. In Asia, there is a lot of activity and here in Europe as well. We have invested in the business development team significantly. We are starting to see, I think, the fruits of that in terms of the number of engagements and the quality of engagements of where they are at. Obviously, it is a pipeline, so people are at different stages. We are obviously focused on some of the ones that are later on in those stages. I would say that I am very happy we are doing everything we are doing delivering to the customers. There is always a timing issue in terms of we are not fully in control of that. The more these engagements that we have, the better.
As we look towards the end of this year and into next year, the health of that pipeline is very strong. I am very confident that that will yield future MLA partners.
You mentioned like line builders. You almost have like a factory blueprint. Does that help accelerate kind of your discussions with future partners that they can begin to scale as quickly as possible?
Yes, it does, and it has almost become part of the buying process now that a lot of our potential partners actually go and visit our partners on who would actually build factories. A typical process would be they will come in, see the technology in Horsham, or see the pilot facility in Redhill, but then they will also go and see the scale of activity and who can actually deliver that as well. I think it is a key part of that sales activity because the pipeline of partners that we have are all looking at how do I produce 700 MW and above? That is the real consideration for them.
Sorry, just one last one. This on kind of the Centrica partnership, and that was quite successful.
Yeah.
It was quickly unlocked, quite a bit of demand already. Is that also something we should see in the future, more collaborations similar to that Centrica partnership?
Yeah, it's something that we're looking at replicating. But I think at the moment, we want to get that Centrica one moving. I mentioned the activity that's going on with Centrica, the white paper, et cetera. They're looking to get units into the U.K. end of this year, beginning of next year, and I think that really starts to accelerate things as well. Because I think once people can actually see the units and the technology firsthand, I think that's an important step.
Good morning. Alex O'Hanlon from Panmure Liberum. Well done on a strong first half. The first question I just wanted to pick up on is something you said, Stuart, around strengthening partner-centric values and behaviors. Could you just give us a bit more detail on what that means and how you kind of track and monitor it?
This is a cultural program that we've got working. We've essentially refreshed the company values, and we've rolled them out, and the people team have done a great job in communicating that across the business. And like any cultural program, actually, the proof of the pudding is in the long term. You bake all those cultural values into your hiring programs and your communications and we're not trying to change massively. The people that are already at Ceres are all mission-focused, very purpose-driven, and we're just trying to make sure everything's perfectly aligned. And how do you assess cultural success? Ultimately, the proof of the pudding is in the long-term health of the business, and we think certainly in the first half, we've seen a good record of execution and the pipeline health's looking good.
I think we think it's working, and the people team are doing a great job in rolling this out.
Great. Thank you. Just one other probably slightly technical question. Last year you signed the Weichai agreement in November, and obviously there's a bit of time that it takes for tech transfer and then therefore, before you can recognize revenue. Should we be thinking in terms of if you're going to sign potentially a new MLA that that tech transfer could happen quicker, or is that two months probably where we should be thinking of? Because I know you've said that you're confident in the GBP 45 million and anything else would be additional on top of that.
Yeah, look, revenue recognition is not that simple.
Yeah
When it comes to big contracts, and it does depend how the contracts are worded, written, and of course, contracts are negotiated by two parties, and they've got to survive the battle, essentially. We do our best to make it as predictable as possible. It's not that predictable. But we're fairly confident that we can both sign and recognize revenue in this calendar year for a new MLA. But we are well aware of our obligations, both in terms of the guidance we've given and the consensus that's out there, that we've got to be very clear and transparent with the market when the time is right.
It's something we track, and certainly, part of the progress we're making is in the investment we've made in our commercial teams is the contracts are now at least templated to be a lot more clear on when the revenue recognition occurs than the Weichai contract, which was a very sort of old, it was an update to a 2018 contract, so it was pretty complicated. We're hoping to make things a bit simpler, but it's not clear.
Thanks, guys. Lacie Midgley, Bloomberg Intelligence. Just thinking about the new MLA economics. Obviously, the backdrop here is completely different to what you were dealing with four or five years ago. Customers, they need solutions, and they need them yesterday. Does that give you more, I guess, leverage at the negotiating table when you're thinking about upfront license fees with partners? Has your thinking around any of that changed given where we are and given how quickly now you can get new factories up and running? Then I think within that as well, if we think about, particularly Phil, you talked about the 800 V DC compatibility, early estimates on longer-term running costs of SOFC being a lot cheaper.
Does that give you any more, I guess the same question, leverage on the royalty fee you can eventually charge, and is there any change in how you're thinking about all of that? I know ultimately there's a higher—
Yeah.
—set up costs here, and you just want MLAs and new partners on board, but has any of that thinking changed at all given the backdrop?
I think we haven't changed our thinking to date on license fees. But obviously, as we're starting to get more demand or competition, I think it certainly helps. It strengthens our position. But the license fees are helpful in terms of the funding of the day-to-day business, but really what's more important is scale-up and royalties. We've just got to be a bit careful that when we're negotiating these deals, if the license fees are too high before people get into the market and pay back, you don't want to skew that investment decision.
But I think on the royalty side, I think given the benefits that we're seeing and the potential of SOFC, I think the royalties then become, let's say, more sustainable, as in you obviously negotiate royalties going into a contract, but five years, 10 years in, you want to be preserving those royalties, and for new contracts, potentially you could negotiate even higher royalties in the future. But it's all about proving out the economics. So short answer is we haven't changed it fundamentally. I would say though each commercial negotiation has nuances, and depends on what the scope is and the size of the customer and the scale of ambition is, the attractiveness of those partners to us obviously has a factor as well. So the longer term is more important to us than the near term.
Understood. Okay. Thank you. And just checking on Delta's second factory, presumably that's covered by the existing MLA, how do we think about other—
Yeah.
—partners that are looking to scale as that demand is there?
Yeah, we do not charge additional fees for additional scale. We do not make it volume limited. We actually want people to scale. Delta has got the license they need to scale, and then it is just the investment decisions on new factories, et cetera. I think the first one, Tainan, was always going to be almost like a development factory because the footprint and everything else was somewhat constrained, and this is a brand-new facility that they are now investing in.
Thank you.
Hi. Skye Landon with Rothschild. First question, on Weichai revenue recognition, are you able to share a little bit about the percentage that was in 1H and percentage in 2H, just as we are thinking about the GBP 45 million? Second question, a follow-up on the partner expansion with Doosan. They have obviously had the success that they have seen in getting orders, getting pipeline in. Have they shown any interest in increasing the size of their initial factory? Thanks.
First question first. The majority of the revenue is going to be Q1 for Weichai because it was signed in November last year, and the full tech transfer happened in the first half. We will have some Weichai revenues in the second half of the year, but the majority would have been in the first.
Second part of the question. We obviously stay close to Doosan, and what we would like them to do at some stage is to move to the Ceres Endura platform because Doosan is an earlier partner around what I would call the first-generation technology, which is the slightly smaller footprint, slightly smaller stack size. But obviously, they are now getting orders. They want to fill that factory. It is an ongoing business decision for Doosan, really, either that conversion or additionality. Doosan, I am sure, will update the market as and when they are thinking about expansion.
Great. If there are no further questions in the room just for now, maybe Merryl can come back to you. I know you have got quite a lot of questions online, some of which I think you may have touched upon. But if I may just hand back to you.
Yep. Why do not we stay on the vein of Doosan? One of the questions are their announcement of the contract with Reverion, what can Ceres expect from the value of those royalty payments, and is this a one-off fee, or will this be ongoing?
Again, it is part of the license deal they have. When they sell product, we get royalties. It is within the standard range that we always say that we receive between $50 and $100 a kilowatt, depending on the scope of what they are selling. We just expect to receive payment via royalties.
Great. Another question which is slightly more technical is referencing the cost competitiveness and how does that impact based on natural gas prices? Are our power partners primarily targeting natural gas as the power source for the SOFC?
It is reliant on the difference between the power price and the gas price. Because basically, very simply what we are doing is if it is natural gas as the fuel, we are taking natural gas and converting it at a 60% efficiency into power or higher if we use the heat or the cooling. It is very much reliant on where you are actually putting this. For example, one of the reasons why it is attractive in the U.K. is we have got some of the highest power prices in the world. Actually our spark spread, the difference between our gas price and our power price, is actually very attractive for this technology. Now, okay, if gas prices go up, it depends on what is the knock-on effect on the power price. There is quite a big margin there. It is competitive today in certain geographies.
It depends on where you are looking at that. To answer the question, today, it is natural gas-based.
Reverion are also tapping into things like the biogas market in Germany, and it can be future fuels such as hydrogen, but today it is natural gas.
Great. Stuart, a question towards you is we continue to spend heavily in R&D with around GBP 48.6 million in 2025, and just querying if we will continue to have that type of R&D expenditure going into the future, or will we see it going down or up?
Well, if you are comparing to 2025, it is going to go down. You saw on the slide the R&D cost went from, say, GBP 25 million in the first half of 2025 to GBP 18 million in the first half of 2026. So that is representative of the crystallization of the effort to produce Ceres Endura. So Ceres Endura, as a project, is now in the commercialized world. We have chosen to have a look at that R&D cost base, optimize it, which we believe we have now done, and that is going to roll forward. So we believe we have got the right number of people in the right jobs to keep on innovating on lifetime and cost without having to be spending the amount that we took to actually get Ceres Endura to the market.
Thank you. One of the questions on a similar vein is, as we intend to sign more partners over the next couple of years, how should investors think about the evolution of revenue mix over the next few years of upfront license fee engineering services versus royalties?
I think today, if you look at the revenue mix, it's that combination, license fees, engineering services.
As we sign more partners, we can expect that for the next few years. Royalties are there, but they are not yet material, I would say. But they should start to grow into next year, in 2028, 2029, et cetera. So royalties will become more of that revenue mix in the future and towards the late stage of this decade, they're going to be significant because that's when we expect cumulatively our partners scaling to the high levels of around 1 GW or more by that stage.
Great. Thank you. One of the other questions was, just given the interest in behind the meter, do we anticipate having more than one licensee this year, or could we have more in next year just given the demand and kind of coming back to that pipeline, just it's come up a couple times. I thought it might be helpful to reiterate.
Look, we've based the business on one a year on average. The thing that is very unpredictable is timing. A few years ago we had two in one year, none in the year before, et cetera. So I think it's entirely possible that you can have a year where there's more than one, particularly as momentum builds. But the guidance we have is one a year, of the quality of partners that we want really gets us to that industry standard.
We do try and think of this as sort of cadence rather than in year, because the year end, albeit we're all in the finance where we all have to adhere to the year end, what we're looking at is an average cadence of one every 12 months. We don't know whether two arrive at once and then there's a gap, or two, then one, then a gap. We don't know which year they're going to fall into necessarily. But what we're looking at the average cadence of the signings of these things.
I think one just final question is, as a U.K. tech company, I'm wondering if we are in discussion with U.K. government to explore initiatives or partnerships that may be available.
We have obviously got a strong relationship with the government. We do various things, trade missions, et cetera. I was fortunate enough to go with the previous Prime Minister on the India trade missions, et cetera. We've done that in the past to Asia. So we do work with government, get government support. In terms of financial support, the business right now is pretty well capitalized.
There might be certain needs or projects where government can help. But we've never relied on government funding, and we don't really rely on subsidies either. We're very much a commercial operation.
We are very proud to be in the U.K., but the global opportunity is there that we are very self-sufficient.
Excellent. I think those cover the majority of the question and the key themes, so I will hand back to you, Phil, for any closing remarks.
Yeah, look, I just reiterate. I think it is a really exciting time in the business right now. We are obviously very engaged on both new partnership acquisition and also not by any means. Our focus is very much on the scale-up of our existing partners at the same time. So we have got the business in the right shape to be able to do both, and we will update you obviously on progress as and when we get more announcements. I think, with our existing partners, they are in that stage of starting to scale, starting to launch new products, et cetera. I think we will get more news flow from some of those guys as well as and when they start to actually come forward. So I think there is quite a lot to look forward to in the next 12 months or so.
Great. Phil, Stuart, Merryl, thank you very much indeed for updating investors. Ladies and gentlemen, we will now redirect you for your feed—
