    This thing seems to require the perfect conditions as well, which may prove even harder to find compared to places for pumped hydro.

    I agree. It’s also a question of how many cycles the impermeability of the rock lasts.

    Also incidents with water ending up in the wrong layers of rock can have dramatic consequences, as seen e.g. in Staufen in Germany. Wikipedia article (in German)

      You and @Thorry84@feddit.nl really summed up my concerns and knowledge gaps succinctly! Don’t want to frac, but don’t want to miss an opportunity, either. Hard to beat pumped, tho. When applicable.
