I thought molten salt storage gets like 90% efficiency. What's the advantage of storing energy by cooling blocks?

[–] Edgelord_Of_Tomorrow@lemmy.world 1 points 1 year ago (1 children)

To run a heat engine you need a temperature difference in order to generate work. When your system generates heat as a byproduct you can amplify the amount of work by increasing the temperature difference. This is how the cold block "stores" energy.

What's your source on 90% efficiency? Here it's stated 35% max.

I'm just talking about storage. Molten salt energy storage is mentioned here: https://en.wikipedia.org/wiki/Thermal_energy_storage
