    You need a buffer with at least 60 TWh in case of Germany. There is no economic electrochemical energy storage system for that capacity.

      The easy solution is to just make green hydrogen. It’s an already solved problem, lacking only political will.

        It is expensive though, so not a self runner in a free market economy.

          It will be cheaper than fossil fuels at some point in the future. The benefit of not being a finite resource. We can speed this process up if we scale up sooner rather than later.

            We are already running out of fossil fuels (particularly diesel) so that’s a given. If we are going to see significant green hydrogen generation, it will likely be in advanced dirigistic economies like China.
