  • Let’s take Europe (because I’m familiar with the data in Europe). Much of the continent is very flat. Denmark, Southern Sweden, Netherlands, and Northern Germany, for example, cannot take advantage of hydro storage, and this comprised the largest storage component of the proposed solution.

    But an additional effect you have when considering the whole of europe is interconnection. The geographic spread of renewables lowers storage requirements.

    We need new battery technologies or other means of economical storage to make such a grid work in Europe. I suspect the numbers are similar in the U.S. Biomass and geothermal help close the gap, but not nearly enough.

    The EU will use hydrogen, I am not a huge fan of that but it is what it is…

    As a sidenote, I don’t expect batteries to play a huge role in energy storage. Propably more frequency regulation and peak shifting and basically no long term storage.

    But we will see…
