Here’s some math Electric mountain is pumped hydro electric storage. It can store 9 gigwatt hours of electricity. The UKs total energy consumption is 1650 Terawatt hours. Let’s say you need to store 4 days worth of energy to account for any shocks. That’s 22 terawatt hours of energy. You’d need to build 2500 electric mountains to store just 4 days of UK energy consumption. And 4 days is a dangerously low buffer for when things go wrong.
