Molten salt and human sweat: the weird batteries that could store renewable energy

The News

The United Arab Emirates is building a massive clean energy project that combines 5.2GW of solar power with 19GWh of battery storage, covering an area the size of 12,600 football fields. Developers claim it will be the world's largest battery scheme, capable of powering half a million homes through the night. Similar innovative storage solutions are being trialed in places like Nevada and Manchester, addressing the challenge of storing renewable energy for use when the sun isn't shining.
