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

        Well, yeah, the hydrogen solution to build out renewable overcapacity and storing production surplus as green hydrogen in natural gas caverns is dead in the water. So private households better start budgeting for sodium-ion backup for hybrid solar inverters which are island and black start capable, for when planned load shedding events start.

      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.
