Former UK prime minister Tony Blair recently argued nuclear power is an “essential part of the answer” to net zero. Writing in the foreword of a report by his thinktank, the Tony Blair Institute, he claimed small modular nuclear reactors, nuclear fusion and other advanced technologies can help lower the emissions of the electricity sector.
It’s worth looking at what these technologies involve, and how far off the UK is from integrating them into its electricity system. But we should first recognise great progress in the electricity sector in the past 15 years, and how dramatic reductions in the cost of wind and solar have led to huge increases in renewable capacity across the globe.
The UK completely removed all coal-fired power in 2024, largely replaced by offshore wind and gas. However, relying on any one technology makes an electricity grid less resilient, and nuclear is zero-carbon and can help stabilise the grid when so much electricity comes from intermittent renewables.
