Sustainable Aviation Fuel Bill

Debate between Lord Ravensdale and Lord Grayling

Report stage
Tuesday 10th February 2026 Lords Chamber

[Lord Ravensdale (CB)]

My Lords, I remind noble Lords of my interest as a chief engineer working for AtkinsRéalis. For my Amendment 7 in this group, I have simply retabled my amendment from Committee. As a brief reminder, we have targets in the SAF mandate —coming back to what noble Lord, Lord Moylan, said about power to liquid—and an escalating percentage of sustainable aviation fuel needs to be power to liquid. That is clearly set out in the SAF mandate. This amendment is trying to ensure coherence between the SAF mandate and the projects given support under the revenue certainty mechanism.

This comes back to what the Minister set out about support for UK production. The percentages in the SAF mandate could simply be met by importing power to liquid fuel, so it is important that we set out the ambition for the industry to meet in producing all that fuel, which is already legally required under the SAF mandate, in the UK, aligning that with the earlier government amendments. I recognise that setting this out in the Bill may be going too far, but I would welcome the Minister’s comments on how this could be set out in the allocation framework documents to give industry that steer on power to liquid fuel and the expectations for producing it in the UK.

My Amendments 14 and 16 are similar to those I tabled in Committee, and I thank the noble Lord, Lord Moylan, for signing them. I reflected on the Minister’s responses at that point, but I did not hear any compelling reasons why HEFA sustainable aviation fuel products should be included in the scope of the Bill. As the noble Lord, Lord Moylan, said, my amendment and his Amendment 15 are very similar and aim at the same thing. Mine deals more with the base product, using established definitions, and his encompasses the totality of HEFA products.

I welcomed meetings with the Minister’s team of officials. The outcome was that the main rationale for retaining HEFA in the Bill is that that recognises that this is a fast-developing market and it is important to retain that flexibility in primary legislation. I accept that, but I still find it hard to imagine a scenario where the Government want to subsidise HEFA using the revenue certainty mechanism. The whole point of the legislation is to help pump-prime those new industries, not to support the well-established industries that we have to provide HEFA fuel.

The Government are taking broader powers than they need under the legislation, so there is a risk that, as we go forward, subsidies could be given outside that intent. However, I hope that the Minister will be able to say something substantive about this in his remarks, on the exclusion of HEFA, and I look forward to hearing what he has to say in that regard.

[Lord Grayling (Con)]

My Lords, I rise briefly to speak in support of the amendments from the noble Lord, Lord Ravensdale, on crops, and to share many of the concerns raised about HEFA. I declare my interests on the register as an adviser to AtkinsRéalis—there are a lot of us here today.

My concerns are that, first, I do not believe that we should be using crops to make fuel. In a world that does not have enough food and where biodiversity is under threat, where deforestation is happening in areas of the world that provide extra land for agriculture, I do not think that there is any justification for growing food and turning it into fuel. I ask the Minister please to exclude crops. The United States is permitting them, and the European Union is not, and I think that we should fall on the side of avoiding the use of agricultural crops. Agricultural waste is a different thing —the residue from crops, such as straw and corn husks. Agricultural waste is one thing, but actual crops is another, and we should not be using them.

On HEFA, we are where we are, but we have to exercise extreme care, because the truth is that there is not enough used cooking oil in the world to fill the supposed need for that used cooking oil. All too often, the suspicion is that somebody is dumping a chicken wing into a tub of virgin palm oil and saying that it is HEFA—so HEFA is something that we need to move away from as quickly as possible. In any case, we depend on imports from the Far East for it, which may not be sustainable going forwards. Our focus should really be on biowaste and municipal waste and on the technologies that offer a really good path for the future —but let us not use crops and let us be extremely careful with what we do with HEFA. I have a lot of sympathy with what my noble friend Lord Moylan and the noble Lord, Lord Ravensdale, have said. It is far from clear that this is a genuine product that has the full potential to do what is necessary.
