Isn't there a third options of building long term energy storage, or is that not feasible at current tech levels?

- Ekaros 2y agoThere is, but making that work is complicated. Math gets easy if you can for example buy power for free during day and then sell it night. 365.25 cycles a year. Say 10-30 years. 4000 to 10000, times your storage capacity. Even cents for each might be reasonable. Now cut this at worst case to 10-30 that is purely storing power in summer for winter. And you really start to need very very very cheap per unit storage. Even multiply couple a times and it is still very tough. Remember we are talking about cents per kwh here. Margin just isn't big.
