Every time I see again the idea of moving big concrete blocks for storing energy, I remember the time I made the calculations, and estimated around USD100K of infrastructure to store the same amount of energy as a nissan leaf.
- standeven 1y agoI did the same calculation. Gravity energy storage is a joke. Came to similar conclusions when running numbers on hydrogen-powered vehicles. Pumped hydro storage and flywheels are cool but ultimately battery storage, distributed everywhere, will win.
- javcasas 1y agoGravity storage is cool when nature has already made most of the work, I/E pumped hydro where nature has already built this huge canyon with a river in the middle just waiting for someone to put a dam at the end.
- imtringued 1y agoIt is really perplexing when people come up with an energy storage method that is even more expensive than just straight up batteries.
