Net Zero, Energy and Transport Committee [Draft]
Meeting date: 13 May 2025
Mark Ruskell
Okay. Is that in the context of society becoming increasingly electrified in terms of both transport and heating, and therefore needing a back-up system to release that energy during winter or at other times when demand is high?

I would welcome that approach. Since the committee last took evidence on this issue, which was in May 2023, we have seen quite a few changes. Low-emission zones have been rolled out in Scotland; there is increasing evidence with regard to particulates from wood-burning stoves; and new scientific evidence is coming along about the impact of air pollution on child development. Therefore, I would say yes to the suggestion that has been made. Now would be a good time to reflect on the evidence, take stock and write to the stakeholders who were part of the initial inquiry.

I note that the two chemicals in question have an impact on human health. The notes say that UV-328 is
“toxic for mammals, endangering human health and the environment (causing damage to liver and kidney),”
while dechlorane affects the nervous system of aquatic animals. It is right, therefore, that those chemicals are being phased out.
Although I accept the Government’s approach and the representations that have been made by the medical industry, I note that those two chemicals will be prohibited in the European Union in autumn 2025. I am content to accept the regulations, but I would like to know whether the chemicals will be phased out on a similar timescale to that of the EU’s. Given that the chemicals have an impact on the environment and human health, phasing them out is the right thing to do.

I will go to Jan Rosenow.

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?

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?
