The US-Israel war with Iran has led to higher electricity bills and put the issue of energy security back in the spotlight.
Now a pilot project inspired by a 100-year-old idea aims to store renewable energy.
Those behind the high density hydro demonstrator scheme near Plymouth say the technology can “turn small hills into giant batteries”, as part of the transition away from fossil fuels.
“This is a first of a kind,” said Stephen Crosher, CEO at RheEnergise, adding the scheme was now operating successfully.
The company was awarded a £8.25m small business research initiative contract from the government’s Net Zero Innovation Portfolio to help develop the project.
