Net Zero, Energy and Transport Committee [Draft]

Grangemouth (Project Willow)

Meeting date: 13 May 2025

Mark Ruskell

Does Mark Symes want to chip in on this?

I am interested in the definition of blue hydrogen as low carbon. That depends on carbon capture and storage being in place and working at a certain efficiency. I am interested in whether you see that as achievable, given that Acorn has not yet been constructed, and whether the capture rates that are predicted for Acorn have been replicable in other CCS commercial plants around the world. If the Acorn project happens, how much certainty is there that you will end up with blue hydrogen and that it will be a low-carbon product, or is there uncertainty about whether what eventually comes out of that process will be low-carbon enough?

Thanks.

The session has been really enlightening so far. We have already had some discussion about sustainable aviation fuel and thermal generation as back-up, as well as the role of hydrogen in relation to that, but I want to return to the questions that I asked the first panel of witnesses about the hydrogen ladder or hierarchy. Do you think that there are particular sectors within that hierarchy on which it makes sense to focus investment? Are there sectors that face challenges? In particular, we talked about where domestic heating sits. I am also interested in what the international picture is in relation to some of those sectors.

I invite Jan Rosenow to answer first.

I want to go back to the issue of the export market to EU countries and the status of blue hydrogen in that mix. If blue hydrogen is going for export, will there be countries that want to buy it? Does it have integrity as a low-carbon form of hydrogen or are the market rules already shifting towards green hydrogen? How long will that blue hydrogen export market exist, does it have integrity now and will it continue to have integrity in the future?

All the witnesses are nodding; I will go to Simon Gill first.

Thank you very much—that is very useful.

Coming back to the sectors that you think will be using hydrogen in the future, I note that the Climate Change Committee does not believe that hydrogen will have a significant role to play in relation to surface transport and is sceptical about its role in domestic heating. You talked earlier about thermal generation potentially using green hydrogen in the future, but as we understand it, SSE has no plans to take Peterhead to hydrogen and use it there.

I know that we are still in the early stages, but I am interested in hearing your thoughts on the sectors where you think that hydrogen has an application. Also, do you recognise the hydrogen hierarchy—that is, the hydrogen ladder of use? Is it accepted that that broadly reflects where the investment potential is and where we can get the greatest decarbonisation for the use of blue—or possibly green—hydrogen in the future? Graeme, do you want to start?

You mentioned the storage scenario in summer, when there is lower demand for heat pumps and more capacity to store energy, but is the real issue not the fact that we need a basket of technologies with regard to electrification? The storage challenge becomes less of an issue if we are thinking about system-wide resilience across the entire year, with different balancing. However, I am also thinking of a situation in which someone with an air-source heat pump in their home is asking why they would also install a separate system that uses a different technology, such as hydrogen.

The focus is on project willow and Grangemouth, but I am also interested in Mossmorran. Nigel Holmes talked about the ethylene cracker at Mossmorran. Do you see hydrogen as part of that mix—whether it is blue or green hydrogen as fuel, or bioethanol as feedstock? Where does Mossmorran sit in that industrial complex?

Where is the incentive, then, to invest in more pilot projects? You will be aware of the H100 project in Leven, in my region of Fife, which is a proof-of-concept project. Are we at a point where we know a lot about hydrogen for home heating now? Is there a need to continue to look at those areas and do pilot projects, or have we now got quite firm conclusions internationally about the applicability of hydrogen for heating and where it does or does not make sense?
