Yeah, I think massive chemical batteries for storing excess electricity to facilitate a contrived green energy market is a bad idea.

    Mechanical energy storage, like pumped hydro or flywheel. Thermal energy storage, like molten salt.

    Electrochemical isn’t entirely off the table either: less-volatile chemistries are available, and better containment methods can reduce risks.

    Non-electrical chemical storage methods are available: electrical energy can be used for hydrogen electrolysis, or Fischer-Tropsch hydrocarbon fuels. Fuel cells, traditional ICE generators, or export it from the electrical generation industry to the transportation industry.

    There’s also avoiding (or minimizing) the need for storage at all, with “demand shaping”. Basically, we radically overbuild solar, wind, wave, tidal, etc. Normally, that would tank energy prices and be unprofitable, but we also build out some massive, flexible demand to buy this excess power. Because they are extremely overbuilt, the minimal output from these sources during suboptimal conditions is more than enough to meet normal demands; we just shut off the flexible additional demand we added.
