Debate between Alan Whitehead and Virginia Crosbie

Committee stage
Tuesday 16th November 2021 Public Bill Committees

[Dr Whitehead]

So that is the window, essentially?

Chris Ball: Yes.

[Virginia Crosbie]

Q If there was no RAB nuclear financing model, what would that mean for our energy security, delivering net zero by 2050 and our dependence on overseas investment?

Alan Woods: Chris made the point earlier that net zero is such an enormous challenge. We often think about decarbonisation in the context of the grid, but the grid in the UK in particular represents about 20% of the total energy we use. The rest of it is heat and transport. As we look to decarbonise heat and transport, there are not that many routes available, certainly in some of them. Hydrogen is one, synthetic fuels is one and of course more electrification, but the common denominator among all of those is that you need more clean electricity. The scale is enormous. We therefore welcome any financing mechanism that will help any industry, not just the nuclear industry, bring forward those clean technologies, because the reality is that we have to have them if we are going to meet net zero.

The implications if we are not innovative with how we approach financing both in nuclear but also in other industries mean that we become dependent on other sources of technologies—imported technologies financed from overseas, which bring with them the whole dependency on other nations for our critical energy infrastructure. Increasing that dependency puts our ability to meet net zero at more and more risk.

Chris Ball: I will take a step back here. Earlier, I mentioned that there is a need for about 9 GW a year of construction to take place each year for the next 30 years. We need to find a way of building everything we possibly can in a way that is most cost-effective for the consumer. In every single area, there will be challenges for us to overcome.

People talk about offshore wind at £40 per megawatt-hour strike price. Actually, when it comes to the last two offshore wind farms—one up in East Anglia and one in Hornsea—one was at about £120 and one at £140 a megawatt-hour initial strike price. I recognise that offshore wind prices have been coming down; that is because of consistent underpinning Government policy. We have to replicate that in each and every one of these areas.

Just because offshore wind prices have come down, does not mean that they will continue to do that; they will reach a plateau and companies will start to go to deeper waters and floating offshore wind prices will pick up. We are also judging things on an old-fashioned measure of the levelised cost of electricity, but for renewables we need to start building in the cost of energy storage as well. That does not come cheap. There is a lot of talk about hydrogen, but that requires a lot of power. For every electron that goes into generating hydrogen, we might get 0.3 electrons back out again; it is not a one for one. That is quite often lost in the debate. Actually, I am a supporter of all these technologies; what I am saying is that we need to look at how we manage those risks.

Net zero will not be achieved without nuclear. From an engineering perspective, the system requires firm power on the grid. The RAB model is a good way of driving forward large-scale nuclear for the benefit of the consumer. Look at the levelised cost of electricity at, let us say, £40 per megawatt-hour for wind, noting my earlier comment, and add the storage costs; if you compare that with nuclear and the RAB model, the prices are very similar. Obviously, Alan also knows the SMR nuclear market very well and would say that, yes, it is similar there.

It worries me that if we do not find a way of pushing all these technologies forward, including carbon capture and sequestration and the technical challenges around that, the risk of failure for the 2050 net zero system is very high.
