Reply to comment by Hyval_the_Emolga in Geothermal May Beat Batteries for Energy Storage: Enhanced geothermal systems are well suited to store excess renewable power as heat. by filosoful

Sounds like while less efficient in terms of conversion, it wins in terms of scale, so if you are okay with some loss of energy, you can store a huge amount of power, which with batteries may be prohibitive.

That could make sense I suppose, like jet engines vs piston.

Look up flywheel batteries, it’ll change your perspective of how energy works

Look up superconducting ring storage. Same concept, but with electron momentum. Don't warm them up above the critical temperature though - that energy has to go somewhere!
