Net Zero, Energy and Transport Committee [Draft]

Grangemouth (Project Willow)

Meeting date: 13 May 2025

Edward Mountain

Our second item is the first of two evidence-taking sessions this month on plans for the future of Grangemouth refinery. Refining there has ceased, and the United Kingdom and Scottish Governments are looking for new uses for the site as a green energy hub.

The project willow study, which is supported by both the UK and Scottish Governments, was published in March. It proposed nine possible projects, four of which relate in some way to the production of hydrogen, and we will discuss those today.

This is an opportunity to touch more widely on the prospects for a thriving and competitive hydrogen sector in Scotland, which to some extent lie behind any aspirations for Grangemouth to be a green hub in the future.

We will hear from two panels of witnesses. On the first panel are Professor John Andresen, professor of engineering and physical science at Heriot-Watt University; Dr Graeme Hawker, chancellor’s fellow in future energy systems, University of Strathclyde; and Dr Nigel Holmes, chief executive officer for Hydrogen Scotland. Good morning, and thank you for attending.

We will move straight to questions. As usual, I have the easy question to ask at the beginning. The project willow study does not advocate the use of either green or blue hydrogen; it says only that a reliable source of low-carbon hydrogen will be required. Which of those production methods will offer the more reliable and affordable supply of hydrogen in Scotland? Nigel Holmes, do you want to kick off by answering that? I will then ask the same question across the panel.

I am sure that somebody will delve into that, but what might concern some people is whether the explosive content in those tanks would be the same as that of gas. If hydrogen goes wrong, does it go wrong big time, compared to gas?

Before we go to the deputy convener’s questions, Douglas Lumsden has a specific question.

I just want to get this clear in my brain. I cannot remember the size of the big pipeline that goes through my farm at home—it is something like 4 foot. It is a big pipeline that goes from Aberdeen to Inverness. If that was converted to pipe hydrogen, it would transmit the same amount of hydrogen as it does natural gas.

Graeme nodded, so I will give him the final word.

I thank the witnesses for giving evidence. As you say, our questions will continue in another panel discussion and into next week. I will briefly suspend the meeting to allow a changeover of witnesses.

I am sorry—you are right. I double jumped—that is a mistake. Sarah, you get the next questions. You look very offended, and rightly so. Off you go.
