And what do you do at night, or on a cloudy day?
There is no grid-scale storage solution.

- pg_bot 5y agoI've been doing some research into cryogenic energy storage and it seems like a universal solution to the grid scale energy storage problem. It uses off the shelf industrial components, can be located almost anywhere, doesn't use any rare or expensive elements, and there is no pollution in the cycle. The general idea is you cool air until it liquifies and store that in large storage tanks when you have an excess supply of energy. Then when you need to discharge the battery you boil the air and run the resulting gas through a turbine. It's also fairly cost competitive with a LCOS of $140/MWh, which is less than the cost of generating a MWh with new nuclear power plants.
