Sustainable Aviation Fuel Bill (First sitting)

Tom Collins Excerpts

Q That is a very good answer; I am happy with that, and it is obviously coming from a company’s perspective. In terms of Government engagement, how many conversations have been had with the Cabinet Office and the Department for Energy Security and Net Zero around energy security and your production capability?

Sophia Haywood: It is not something that we have had great levels of conversation about, particularly when it comes to energy security. It is a really important part of energy security. Coming back to the point about access to locally produced bioethanol, I see it as another great example of something that would be sustainable, affordable and secure, if we are able to take wheat that is produced locally by British farmers, and convert it in local facilities and then at a SAF facility. With all the additional benefits on things such as CO₂, that is a great opportunity on energy security, but speaking more broadly it has not been a huge part of the interest in SAF.

Noaman Al Adhami: I will focus more on scalability. When it comes to scalability, allowing all the routes to SAF and not focusing on one route will potentially enable SAF production to be scaled up. Green hydrogen will also potentially be there in large quantities with an affordable price, and that will contribute. For example, we could utilise green hydrogen to triple production if it were available, but currently it is not.

We are also designing our plant to utilise multiple types of feedstocks. It is mainly solid waste to SAF. I would start with a less challenging feedstock to prove the line-up and then explore much more difficult feedstocks, such as MSW. Even sewage sludge, chicken manure and grease, for example, could be used to co-fire the gasifier, so we think the supply chain will potentially build once it sees a home for their waste.

We will start with a safe option for the feedstock, but our objective is to explore all other potential feedstock and increase capacity. We have plans for at least phase 2. Our site in Teesside can accommodate phase 2 and we are already planning for that. Hopefully, once we reach FID, we will announce phase 2 of the project.

Q You have talked a little about this already, but I am interested in the conditions you are operating in and the constraints you are facing. You mentioned regulations and planning, but I am also interested in the availability and maturity of standards and the particular different types of biofuel. I am also interested in how you store intermediates and if there are any issues around that, because I have heard from others that there is perhaps a lack of regulation on the safe storage of some of these intermediates. I do not know whether you are using hydrogen for upgrading at all, but I am interested in whether you have a vision for a future UK hydrogen system, and what that might look like.

Noaman Al Adhami: In terms of standards, as I mentioned before, our route is approved as per the ASTM route. The rest of the standards—mainly on feedstock—are already there in the SAF mandate with all the details, and we are complying with that. I think one of the big advantages of SAF, compared with other means of decarbonising aviation, is that it is a drop-in fuel. It is a liquid fuel, very similar to the jet fuel kerosene, so it is easy to store and transport; you can use existing pipelines.

Obligated parties, whom we may potentially supply with SAF, have the capability to blend it. Currently, it can be blended up to 50% drop-in, and they can do so using the infrastructure that is already available. If you compare hydrogen with SAF, SAF is much easier, because you can use the existing infrastructure in airports, storage and logistics. To be frank, we do not see any challenge there in Teesside, which is an industrial area with storage facilities. We do not see any issues. With hydrogen, as I explained, we can use hydrogen not necessarily to power the plane directly, but we can certainly use it to boost production of SAF. That is possible. I have the CO that I mentioned earlier, which I am currently capturing to reduce carbon intensity. I can convert this to CO, mix it with hydrogen, and produce more SAF.

The issue in the UK is the cost of producing green hydrogen. We, as a global developer of renewables, know the cost of producing green hydrogen in the UK is very high. If you have this valuable green electron, is it better from an efficiency perspective to use it to electrify cars and heat homes, where you can get up to 80% efficiency, or to produce fuel at 30% or 40% efficiency? But things are happening; once hydrogen storage and production costs advance—we think perhaps between 2035 to 2040—hydrogen will potentially be available in quantities. We will need large quantities, of course: for our project alone, we will need 1 gigawatt of hydrogen to fully utilise the biogenic carbon we produce.

[The Chair]

I am afraid you have just two minutes left.

Sophia Haywood: Just quickly on planning, it is more about boots on the ground than a lack of skills or particular challenges within planning. That is something I have heard from many other SAF producers all over the UK, so that would be my point there.

Similarly, in terms of standards, we also have ethanol-to-jet, ASTM approved, at 50%. That is fine for the current mandates, but as we move towards potentially greater blends of SAF in the mix, more work will be needed to increase the blend limit from an ASTM perspective. I am not aware of any issues on the diesel side—we produce 90% SAF and 10% diesel—but of course I can go away and check, and report back. The same applies to the storage of intermediates; ethanol is a well-transported product in many ways, shapes and forms. Again, I am not aware of any particular challenges there, but I can double-check and—[Interruption.]
