| For district heating, sure. For electricity? Yes, in theory, but not at efficiencies that would make financial sense. |

| do efficiencies matter that much when you don't need much and can "charge" with "free" energy? |
| |
| ▲ | bryanlarsen 3 days ago | parent [-] | | Higher efficiency storage can outbid you for the "free" energy. | | |
| ▲ | tcfhgj 3 days ago | parent [-] | | perhaps, but the other way around is a possible scenario as well, because it may still be cheaper to have inefficient storage when the way you store the energy is expensive (e.g. some batteries may have very high efficiency, but you need difficult to obtain materials) | | |
| ▲ | bryanlarsen 3 days ago | parent [-] | | LFP batteries are > 95% efficient and only use common elements. | | |
| ▲ | tcfhgj 2 days ago | parent [-] | | It was just an example for explanation | | |
| ▲ | bryanlarsen 2 days ago | parent [-] | | It's your core argument > when the way you store the energy is expensive batteries are cheap | | |
| ▲ | tcfhgj 2 days ago | parent [-] | | it's an illustrative example for my argument > batteries are cheap a metal box for storing synthetic fuel is cheaper |
