Net Zero, Energy and Transport Committee [Draft]

Sustainable Aviation Fuel Bill

Meeting date: 30 September 2025

Bob Doris

Graham, can I come in here? I read the briefing papers in the past few days, and this is all new to me. I get what you are saying about the major adaptations that would have to be made to storage and so on. Could liquid hydrogen be used for short haul, say Aberdeen to Dublin or Glasgow to London? Could there be fleets that service that market? Is that worth pursuing?

Sustainable Aviation Fuel Bill

Meeting date: 30 September 2025

Bob Doris

That is helpful, because my next question was going to be about battery electric for planes. Hold on to that thought, because I want to know whether the other witnesses have any views on liquid hydrogen. All that I can go on is the notes that I made in preparation for the meeting, which say that, by 2027, we are looking at 80-seater planes using liquid hydrogen for short haul. The question is whether, if technological advances go further, that is worth pursuing. I have no view on it. The committee wants to ensure that every aspect of technological advancement to pursue net zero for aviation is being explored. Liquid hydrogen is one of those technologies, so I want to tease that out. Are there any other views on liquid hydrogen? If not, perhaps you could comment on the use of battery electric for planes. Sebastian? Hold that thought, because Mark Morrison is taking up the cudgels.

Sustainable Aviation Fuel Bill

Meeting date: 30 September 2025

Bob Doris

Before I move on to Mark Morrison, do you want to say anything about battery electric aircraft, Dr Eastham? I think that it said in our papers that Norway is hoping to move by 2030 to all short-haul and some medium-haul flights being battery electric, with the new fleets for those flights being almost exclusively battery electric.

Thank you.

Sustainable Aviation Fuel Bill

Meeting date: 30 September 2025

Bob Doris

It is almost as though you knew that I was going to mention hydrogen and did a link for me, convener.

I know that we have spoken about hydrogen, and Graham Hutchings in particular talked about some drawbacks of using liquid hydrogen in flights. We spoke a bit more about using it as a power source to produce SAF, but there are opportunities for using liquid hydrogen directly as an aviation fuel, not as SAF, because it is not a drop-in fuel. Does it have the potential to lower emissions and be part of the mix in making aviation carbon neutral? Given that I have taken Graham Hutchings’s name in vain, perhaps we should go to him first.

Sustainable Aviation Fuel Bill

Meeting date: 30 September 2025

Bob Doris

That is helpful.

Mercedes, I will bring you in, but because of time constraints, I will ask you an additional question. You can answer this final one or you can reflect on the two that I have already asked—that is up to you.

I have a wee note that says that there have been really good improvements in fuel efficiency over a number of years. Have we squeezed that as far as we can, or can we make more improvements?

That particular question does not have to be for you, Mercedes. I have asked three questions now; do you have reflections on any of them? If any of the other witnesses want to come back in on any of those, I would also be delighted to hear from them.

That is very helpful. Do any other witnesses have final reflections on the questions that I have asked?

Okay. Thank you.

Social Justice and Social Security Committee [Draft]

Pre-budget Scrutiny 2026-27

Meeting date: 25 September 2025

Bob Doris

I will start by asking you about the language used around social security spend. Depending on who is talking, it is an “overspend”, a “black hole”, an “investment” or “planned expenditure” by the Scottish Government and Social Security Scotland. That language is quite important. Do you consider there to be an overspend in the social security budget or do you believe that it is planned expenditure beyond what would have been spent anyway had we just followed Westminster’s policy agenda? Given that the language is quite important when we talk about our budgets, could you comment on that?

Pre-budget Scrutiny 2026-27

Meeting date: 25 September 2025

Bob Doris

We are hearing that it is about getting the balance right.

I mentioned that we spend nearly half a billion pounds on the Scottish child payment and £649 million to mitigate Westminster decisions. That is cash in the system at play. Given that this is pre-budget scrutiny, have any of the parties in the Scottish Parliament suggested that we should divert the half a billion pounds, or a portion of it, from the Scottish child payment, or that we should divert the £649 million, or a portion of it, to other endeavours rather than make the planned investment that the Scottish Government has currently outlined for those funds?
