    Couldn’t we pump water into dams during times of surplus and then drain the dams for hydroelectric when needed? Is that not feasible at scale?

      Not everywhere has the geography to dam and use water like so. But there’s other non-lithium energy storage methods in the works.

      Off the top of my head, concrete blocks, compressed air, liquid metal batteries, heat batteries, and flywheel based energy storage.

      There’s more too, if you’re curious.

      HVDC links between countries will also make renewable energy transmissible to places around the globe that need it, so sun shinning in one country can be transmitted to where the demand is.
