To go back to what Fergus Ewing said, there is an opportunity for constrained power to be used to produce green hydrogen, although the potential for that has not yet been exploited at scale. As you rightly said, in your constituency, the H100 Fife project is leading the way in proving the point that hydrogen could be safely used for heating homes. There are different views on whether that is feasible from a cost point of view, but the H100 project is seeking to prove the concept. I was delighted to be able to visit it to see what it is doing.

Water usage, whether for hydrogen or anything else, is continually assessed by Scottish Water and SEPA. Hydrogen would not be the only high water usage industry. There are many high water usage industries in Scotland, including breweries and distilleries, and hydrogen would be another one. We would need to ensure that we had the volume and the capacity to allow that. Anyone who required to use a great deal of water would have to engage with SEPA and Scottish Water on their plans before they could implement them, because their business case would depend on that water being available. They would need to assess whether they had the volumes that they needed before they put in a planning application associated with what they wanted to do.

In general, water scarcity is becoming a more pressing issue in Scotland. Last year, we had record water scarcity, and river levels were very low. That started a lot earlier in the year than is usually the case. SEPA issues licences for water abstraction from watercourses, and quite a number of people who would ordinarily apply for such licences, such as farmers, were told that they could not take water from watercourses over a period of several months.

Scottish Water monitors the volumes in its reservoirs. Until fairly recently—up until the past few months—Scottish Water’s reservoirs were back at their normal levels, except in Dundee. People think that “sunny Dundee” is just something that a Dundonian came up with for a laugh, but it is genuinely true—rainfall levels in the Dundee area are a lot lower than those in the rest of Scotland. That is why Scottish Water has implemented a household usage pilot in Dundee.

Given the more general concerns that exist, Scottish Water, SEPA and the Scottish Government are working together to produce water scarcity reports and assessments of where water is needed. Consideration needs to be given to the availability of water, whether to produce hydrogen or for anything else. For example, a lot of the beer that Brewdog makes is made in my constituency, which is where the company’s headquarters is. Brewdog had to engage with Scottish Water, because it wanted to expand and it required more water. At the same time, planning applications for new housing developments were going through the council.

An assessment is made at local level of what water is required in particular areas, and that would be the case in relation to hydrogen production.

More generally, your question gives me the opportunity to mention a hobby-horse of mine. We must start treating our water as a precious resource. The fact that it is rainy in Scotland does not mean that we have an abundance of water. We have the best water in the UK when it comes to water quality. However, the supply is not infinite, and we should not take its availability for granted. Scottish Water puts millions of pounds into upgrading its facilities to stop leakages and to bring down the emissions associated with processing our water, and SEPA constantly monitors our river sources and our watercourses.

If a hydrogen producer wanted to invest an awful lot of money in a way that involved counting on water coming from a particular watercourse, that would have to be bottomed out with SEPA well before it put in a planning application.

If someone is in danger of being told by SEPA in the months between April and September that they might not get a licence to take water, that is a pretty precarious position for their business to be in. A combination of all those things applies not just to hydrogen but to anyone who needs a water supply to run their business or housing development, or whatever it is.

SEPA is doing a bit of work on that at the moment. I was interested to see the petition come through, so I reached out to SEPA, which has a working group that is dedicated to pump storage hydro. It is exploring all the challenges that are associated with pump storage hydro and the interaction with watercourses and whether there would be loss or whatever. The group is also looking at the cumulative impacts and at the lack of formal co-ordination agreements for developers who are working on the same body of water. It is also looking at the impact of pump storage hydro on fish more generally, which includes the subject of the petition.

SEPA is developing guidance on the consideration of the cumulative impacts, and I believe that it will consult externally on that. I do not know whether it is doing that yet, but I can find out when it will. That will give the people who lodged the petition and people who are interested in the issue an opportunity to engage in the consultation and to provide their knowledge of the impacts that pump storage hydro is having.

The process that SEPA is undertaking is on-going, and I do not have the results of it. I also cannot talk about live applications, as members know, so I am not going to.

However, SEPA is taking an active look at some of the issues that were brought up in the petition and those that Fergus Ewing mentioned to do with the potential cumulative effect of multiple pump storage hydro developments. We will find out more about that from SEPA, including when it is due to do its consultation.

That is when the spatial energy plans will be delivered, so I hope that the strategy will be published by then. However, we have had some curveballs recently. We have had the Finch verdict and various other Supreme Court verdicts, which we must assess so that we can come to an informed view on all those issues and what we think needs to happen. As long as there are no more major curveballs, I hope that the strategy will be published by then.

That was the result of a combination of a couple of things. There was powdery snow rather than the sort of snow that sticks to overhead transmission lines. I am giving my layman’s assessment, given that I was at the relevant Scottish Government resilience room meetings. There was also a lack of wind—on the whole, it was not particularly windy. Storm Arwen was particularly bad in causing outages because there was an unusual wind pattern that brought down trees in winter, when there would not normally have been wind coming from that particular direction. Trees grow to withstand the wind that they expect. Every day is a school day when you speak to people who deal with such outages. Storm Arwen caused a lot of tree fall, which brought down a lot of lines. On this occasion, there was mainly a particular type of snow and there were not the kinds of winds that would bring down power lines.

We will reach out to SEPA and, as and when any information becomes available, we will pass that on to the committee.

Every point that Fergus Ewing has just made I have absolute sympathy with. That is why we have asked NESO to do the strategic planning work that I mentioned in response to Maurice Golden. The assessment that it will undertake will give us that detail. It is all about energy security.

On constraint payments, I think that they are an absolute scandal, to be honest, and they are one of the reasons why we need to improve capacity in the grid. Why are we paying developers to stop generating? Most people in Scotland will find it absolutely unbelievable that that is the case. That energy—that electricity—has nowhere to go, and the grid upgrades will allow more of it to go into the grid and to be used.

There are also opportunities for more local offtakers to take that electricity, too, and the Scottish Government has been looking at heat networks—the work that Màiri McAllan is doing—and at the high-intensity industries that we are trying to encourage to come to Scotland, as part of the work that Kate Forbes is doing with the green industrial strategy.

The work that we have asked NESO to do will be absolutely fundamental to how we go forward. We need to ascertain where the energy security and resilience weak spots are and plan accordingly, and that very important work needs to be done to inform what we, in turn, will do. That future strategic spatial energy plan is, in effect, what we have commissioned NESO to do, and it will allow us to ascertain exactly where the weak spots are in the Scottish grid and in energy generation. We can then plan on that basis with the expert advice that it will supply us with.

Okay—I just wanted to clarify that.

I want to make it clear that we have pushed the UK Government to introduce reforms on community engagement as a result of exactly the kind of stories that you have told the committee. Under the devolved settlement, we do not have the ability to make conditions on community engagement and community benefit mandatory and we do not have many of the levers that are associated with electricity infrastructure developments. We have set out good practice principles, but they are toothless, because we do not have those powers.

I engaged early with the UK Government’s energy minister after he was appointed and we discussed these sorts of issues and the need for those two areas to be mandatory, rather than just being set out in good practice principles. We have turned a corner, because a code of practice has been consulted on. The 2025 act is a real step change and provides an opportunity to reform the process and to put such mandatory conditions in place. The next step would be to mandate community benefit, which we talked about previously.
