'Invest in energy storage': how should UK fill energy gap left by nuclear cancellations?

The UK's long-term energy supply is at risk after three nuclear projects, which could have provided 15% of electricity demand, were cancelled. Following the suspension of plans at Wylfa Newydd, we asked our readers how the UK should fill the gap.

"Invest in energy-storage systems so that all available renewable energy can be used efficiently, without just connecting an intermittent supply into the grid. Secondly, if the UK can build nuclear plants for submarines it could use that technology to install small power stations on the grid."

Clive Renton

"By using small modular reactors (SMRs). They would be manufactured in works, and assembled at site, saving time and cost. All the existing nuclear power locations could have up to, say, four SMRs."

Peter Maitland

"We need a coordinated strategy that accepts there’s a place for carbon sources in the supply chain while planning for a future where our energy will be sourced differently. A blinkered emphasis on renewables won’t in itself keep the lights on."

Geoff Donkin

"Renewables are becoming ever cheaper, whereas nuclear is becoming more expensive. We will save a lot of money through the cancellation of nuclear projects. Of course, we will need energy storage and more interconnectors to deal with peaks and troughs. There are lots of technologies out there that need investment, including liquid-metal batteries and vehicle-to-grid. Exciting times!"

Stuart Kirby

"It is essential that Britain finds other main contractors to deliver nuclear-produced baseload electric power to the grid to avoid further reliance on gas-fired power stations. The politically expedient dates for eliminating petrol and diesel-powered road vehicles mean a great expansion of electric power requirement, which cannot at present be met."
