Lords ChamberMy Lords, it is a pleasure to take part in today’s debate. I join all speakers—or perhaps all—who have congratulated my friend, the noble Baroness, Lady Brown of Cambridge, on securing it and on chairing the committee with great skill and good humour. I also thank the staff for their tremendous help in producing today’s report. I am glad that the House has had an opportunity to debate it relatively soon after its publication. That may seem strange to some new Members—January 2025 is not particularly close to March 2024—but, considering our subtitle “get on with it”, I hope the new Government will react to this report and debate in that spirit. I say “new Government” because most of this inquiry was conducted under the old Government. Like all other Members, I look forward to the maiden speech of my noble friend Lady Gustafsson, who will join that relatively rare and select group of Members who make their maiden speeches as Ministers and not as Back Benchers.
I have been reflecting on the coincidence that we are having our debate on the same day as the state funeral of President Jimmy Carter. You may think there is no connection but, looking back, one of his achievements was to set up the Department of Energy in the United States in reaction to the oil crisis of the 1970s when OPEC became a well-known word throughout the world. We had set up our own Department of Energy a little earlier; it was 50 years ago this year that the first of the North Sea oil came through.
So, 50 years later, we find the energy landscape transformed and the public are now well adapted to the fact that energy policy shapes their lives. They instinctively realise that the phrase “net zero” is a further transformation which will dominate lives, even if they are not familiar with some of the details of this change. Today’s report should be seen in that context, given that many of the details may not be easily grasped by the public.
As you would expect, we took a lot of very detailed evidence for the report from a wide range of experts. Even on some of the most important areas, such as the need for a strategic energy reserve, there were widely varying views on how large that reserve should be. We know that the Government’s targets are ambitious and the wish to be largely decarbonised by 2030 brings forward the date, so it is all the more important that a committee such as ours takes on an issue such as this and gives it the prominence it deserves. Let us face it, LDES as an acronym does not exactly trip off the tongue, but it represents an important and vital ingredient of our future energy policy. The net-zero policy to which we are committed will mean that we use electricity far more than we do now, and it will be derived from renewable sources. We will specifically use wind and solar, both of which we have a great capacity for.
The residents of a place called Odiham in Hampshire, as noble Lords will recall, last autumn went for an entire week without any recorded sunshine or wind. There is a special word to describe this—I think the chair has already beaten me to get it into Hansard—but we have got to deal with a world in which the sun does not shine and the wind does not blow, otherwise we run the risk of power cuts. The chair alluded to how close we came relatively recently to what many in the world would call “load-shedding”, which is something a first-world country such as ours should not countenance.
In the short time available, I have a few questions for the Minister. First, what is the Government’s current assessment of the scale of the need for LDES and how will it fit into the new energy system? Secondly, what progress is being made in setting up the National Energy System Operator and what effect will future reforms to the planning system have on implementing decisions once ministerial approval is given?
Thirdly, what plans do the Government have for a strategic energy reserve? Will that reserve be gas or might it be an alternative such as hydrogen? Fourthly, if it will involve green hydrogen as a long-duration energy store, how will this fit into the Government’s wider hydrogen policy? What plans do they have for a domestic electrolyser industry, not to mention greater public consultation on its potential use?
Fifthly, what progress is being made towards a strategic spatial energy plan? Sixthly, what plans do the Government have for speeding up the ability of renewable energy sources to connect to the national grid? When we look back on this in years to come, it will be a scandal that it took so long. Seventhly, when the grid connection queue has finally been shortened, what steps do they plan to take to enable electricity to be transferred across the country—even across beautiful parts of this country—by the building of new pylon networks? Can this be achieved without timely reform of planning laws?
Eighthly, is there anything the Government can tell the House about plans to minimise the need for long-duration energy storage, including the use of interconnectors—always bearing in mind that, in today’s dangerous world, as undersea cables are severed, so could undersea connectors? Ninthly, what government support is being given to R&D into other LDES technologies, such as compressed air and battery chemistries? Tenthly, can the Government explain how LDES can and will fit into their longer-term net-zero objectives? Will gas-fired plants be used for LDES? If so, will they be fitted with CCUS?
In conclusion, when a major committee such as the Science and Technology Committee tells the Government that they should get on with it, I want the Minister to know that it is meant in the kindest, friendliest way—but it is meant.
