Apr 10, 2026 - UK hydropower breakthrough could unlock clean energy in once unfeasible locations
As energy security concerns grow alongside volatile oil prices, a game-changing innovation in hydropower could make it possible to generate and store clean energy on ordinary hills – not just mountains or dams. Engineers in the county of Devon, southwest England, are testing a new approach that replaces water with a dense, mineral-rich liquid. This development could bring reliable power to communities in areas once considered unfeasible. The technology, developed by energy storage company RheEnergise, comes after years of chemical and engineering research. John Bevir reports for CNA.
