A giant flywheel project in Scotland could help stabilise the grid and reduce blackouts in the UK.

Designed by engineering giant GE, the flywheel does not generate electricity or produce carbon emissions – but instead mimics the frequency-stabilising effects of large power station turbines without using fossil fuels.

Windfarms can be kept running for longer as a result, increasing the grid’s ability to rely on renewable sources over gas powered plants.

Julian Leslie, the head of networks at National Grid ESO, said to the Guardian: “This approach is the first of its kind anywhere in the world and is a huge step forward in our ambition to be able to operate the GB electricity system carbon-free by 2025.”
