Net Zero, Energy and Transport Committee [Draft]

Grangemouth (Project Willow)

Meeting date: 20 May 2025

Mark Ruskell

Yes. I have a quick question. Tim Dumenil mentioned Mossmorran. How do you see Mossmorran potentially fitting in with the hydrogen options from project willow?

I think that Professor Andresen was talking about CHP systems that were set up on the back of existing industrial sites, which is quite a niche application.

Yes. I will bring in Tim Dumenil in a second, but I was struck by something that Lewis Elder said earlier. The potential demand for all the project willow projects would be around 20GW of generation to do the electrolysis and create the hydrogen.

Does that conflict with what you said earlier about blending hydrogen into the gas grid? If we have the demand for a huge amount of power to produce as hydrogen—and potentially we cannot meet all the projects that could be developed through project willow—why would we then want to put it into the gas grid? Surely we should focus the hydrogen production on two or three applications coming out of project willow. Are you making the case for blending hydrogen into the gas grid as a way of pump priming things? If you are, how do you get out of that to use the hydrogen where you really want to put it, which might be in a fertiliser factory or some other form of derivative manufacture where you do not have any alternative but to use hydrogen because electric will not cut it? Does that make sense?

The concern, though, would be that we then build in dependence on natural gas, which will be 90 per cent of what flows through the pipes—10 per cent might be hydrogen. If this is seen as a transition, how do you make sure that there actually is a transition, rather than effectively locking in dependency?

No, I am fine.

Okay. Thanks. Stuart, do you want to comment?

Mark Ruskell

Thanks for those answers.

Going back to hydrogen, I would like to ask a question that I asked the first panel, about which sectors we should prioritise for hydrogen use. We have had some discussion, in the past couple of weeks, about the potential to bring back fertiliser manufacturing, and we have talked about hard-to-abate sectors in particular. There has been some discussion about the wider use of hydrogen in heating and its applicability or otherwise. I am interested in your thoughts on that.

Mercedes, you are nodding. Would you like to come back in on that?

I want to hear some more of your reflections on the sectors that you think should be the priority for hydrogen use. You will be aware that there has been some discussion of an appropriate hierarchy of hydrogen use, and Tim Dumenil has already talked about the right-use case for hydrogen and really drilling down into those sectors.

From your earlier comments, Mark, I take it that you see no use for hydrogen in the domestic heating sector. Is that right?

So, which sectors should be prioritised for hydrogen use?
