Battery storage ranges from $150 to $300 / kwH capacity. The entire grid would need something like 5twH of capacity for an 8 hour ride through. I want you to carefully consider those prefixes and the vast, vast Gulf of space between them.
Nah, you can buy retail packs for less than $300/kwh now, I installed some recently. Commercial installs in China are reportedly hitting like $60 installed.
Also, 4 hours is the target Jigar Shah talks about for getting solar to a load factor roughly equal to most thermal plants.
Also, I believe that’s 4 hours on the nameplate of the variable generation, not 4 hours on the entire grid load. People generally aren’t advocating for going fully variable generation.
Also please give a source as to why the US grid would need 5 TWh of battery storage. So we know it is not simply a number you invented out of thin air to say ”impossible!!!!”
