I heard the loss comes from evaporation. Another cool idea I heard was using a mining cart. So its not practical but I think the idea is cook because I’m pretty science illiterate but it got me thinking about what a battery actually is. So you drag a mine cart up a hill with energy produced using renewable energy and then let it go down the hill and collect the stored energy with its motion. Technically there isn’t anything like evaporation so you could store the mine cart up the hill with no energy loss.
