you done need rare earth minerals to store energy at a massive scale you need more of those https://www.electricmountain.co.uk/ https://www.electricmountain.co.uk/ but those aren't cheap, wont be build by private industry, and is so ancient a technology that the startup scene will play no part in it.
Otherwise you are right the really big problem right now is that we don't have a suitable replacement for oil that wont also change society in ways nobody is willing to deal with yet.
Fission is not going to be small and safe enough to really replace oil, fusion does not yet exists in the real world, so were probably stuck with renewable untransportable energy infrastructure for any future growth.
- thewarrior 5y agoHere’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.
