[–] IndefiniteBen@feddit.nl 2 points 2 years ago (1 child) I thought molten salt storage gets like 90% efficiency. What's the advantage of storing energy by cooling blocks? permalink fedilink source parent hideshow 2 child comments replies: [–] Edgelord_Of_Tomorrow@lemmy.world 1 point 2 years ago (1 child) 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. permalink fedilink source parent hideshow 2 child comments replies: [–] IndefiniteBen@feddit.nl 1 point 2 years ago I'm just talking about storage.
