Wind and solar is all you need. Power2Gas is a viable technology for seasonal storage.

  It's ~50% efficient as compared to ~80% for pumped storage. Synthetic kerosene for making jet fuel or using syngas to make green fertilizer might make sense as a decarbonization strategy but as a means of "storing" electricity it's kind of pointless.

    Pumped storage doesn't scale though. And in the end, efficiency doesn't matter, only cost does. Fossil fuel power plants are 40% efficient, but they're still profitable.

      It scales just fine. There are thousands of viable locations. Far more than we need.
