Net Zero, Energy and Transport Committee [Draft]

Grangemouth (Project Willow)

Meeting date: 13 May 2025

Edward Mountain

I have a question on that specific point. It is my understanding that, compared with natural gas, it is possible to move a lot more hydrogen in a smaller pipe. Is that right?

Grangemouth (Project Willow)

Meeting date: 13 May 2025

Edward Mountain

Welcome back. We will now hear from our second panel of witnesses on the hydrogen aspects of the project willow study. Joining us in the room is Dr Simon Gill, independent energy consultant and author of “Green hydrogen in Scotland: A report for Scottish Futures Trust”. Appearing remotely are Dr Jan Rosenow, energy programme leader and Jackson senior research fellow at Oriel College, University of Oxford, and Professor Mark Symes, professor of electrochemistry and electrochemical technology at the school of chemistry, University of Glasgow. I welcome you all. Somewhat bizarrely, Simon, the fact that our online witness appear on a screen below you, which is facing me, makes it look as though you are flanked by them.

If you were listening to the first part of the meeting, you will have heard me say to the first panel of witnesses that my first question is the easy one. Project willow did not advocate for the use of either green or blue hydrogen but said only that a “reliable source” of low-carbon hydrogen will be required. Which source do you think is most likely to offer Scotland a reliable and affordable supply of hydrogen? I put that question to Mark first, before coming to Simon Gill and Jan Rosenow.

I am looking at those online now. Does anyone want to come back on that before I move to Kevin Stewart?

No—I am impressed. You were quicker to respond than our witnesses who are online.

Thanks, Kevin. The next questions come from Douglas.

United Kingdom Subordinate Legislation

Meeting date: 13 May 2025

Edward Mountain

We will write to the Scottish Government on that basis. We will also ask the Government to tell us the timescale on which it proposes to ban the chemicals.

Thank you. We will write to the Scottish Government to that effect.

Petition

Meeting date: 13 May 2025

Edward Mountain

The next item of business is consideration of petition PE2123. The petition, which has been lodged by Asthma and Lung UK Scotland, calls on the Scottish Parliament to urge the Scottish Government to amend the Air Quality Standards (Scotland) Regulations 2010 by setting new limit values for nitrogen dioxide and fine particulate matter in order to align with the World Health Organization’s 2021 air quality guidelines.

The committee first considered the petition in April, when it agreed to write to the Scottish Government to get an update on its review of its strategy, “Cleaner Air for Scotland 2: Towards a Better Place for Everyone”. The Scottish Government responded on 22 April, and its letter is provided in annex B of the relevant paper, which also sets out some options for going further.

Do members have any views?

Grangemouth (Project Willow)

Meeting date: 13 May 2025

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?
