Sustainable Aviation Fuel Bill (Second sitting)

Debate between Paul Kohler and Tom Collins

Committee stage
Tuesday 15th July 2025 Public Bill Committees

[Tom Collins]

Q You have mentioned that the UK is taking a strong leadership position on this stepping-stone technology with SAF. If the UK were to prepare itself now, early on, to be in a leadership position in sustainable aviation using hydrogen, what do you think that would look like?

Matt Gorman: I think it would look broadly like what the UK is doing. We think about it in three buckets: the plane, the airport infrastructure and the regulatory environment. It is worth remembering that UK aerospace is one of the jewels in the crown of our manufacturing sector. We have a very long history in aerospace, and the Aerospace Technology Institute funds some of that technology development alongside the private sector. That is important.

With airport infrastructure, we have always said, certainly for Heathrow, that we do not want to be a blocker. We do not want a hydrogen plane to be designed but not able to fill up at our airport. We keep an active watching brief on technology developments. We have taken a stand at Heathrow to trial hydrogen technology so that we can understand and build understanding. That is partly to influence the regulatory environment so that we are supporting the roll-out of hydrogen.

The latest views from manufacturers are that we will probably start small with hydrogen—small plane sizes and small ranges—and build confidence there before getting bigger. However, that could play a real role in domestic connectivity. I think we are doing the right things, but it is a both/and with SAF and hydrogen, not an either/or. I would also say that SAF is the solution that we know exists today and that we can deploy today, so we need to get it moving.

Q First, given the obvious international aspect of aviation, does it make sense for the UK mandate and the EU mandate to diverge, or would it make more sense if they were the same? Secondly, we heard from one witness that the levy would encourage tankering, with air operators filling up in other locations. Does that happen now, and is it an issue that you can see being made worse by the levy?

Matt Gorman: On the first question, I touched earlier on the fact that the EU and the UK have taken different trajectories, certainly into the longer term. I will be a little bit careful in what I say, because we are just finalising our thinking on what we submit to the Government, but increasing ambition with SAF will be important in the UK as we build confidence in production and scale-up of the technology. We can see a case in future to be more ambitious with the UK mandate. I think the Government said that they want to keep that actively under review, which we support.

On the question of tankering, it happens to a limited extent today. We do not fly the aircraft, but our understanding, from when we last looked at it several years ago, is that on short-haul aircraft in particular, where there is a very rapid turnaround and you do not necessarily want to take time to fill up the aircraft at the other end of the route, the CO₂ penalty was not huge in terms of the industry overall. I am not close enough to comment on whether the levy poses a particular challenge there, but when the Government get to the stage of consultation on the detailed design of the mechanism and are working with the industry, it will be important to design it in a way that avoids that wherever possible.
