My point is mainly that there are plenty of options available to stabilize grid prices that are way cheaper than using EV's. Europes energy crisis is temporary,

  which other options are feasible today outside hydro pumping?

    Isn't that the big question? Whoever is confident that they have correct answer to that question should invest any coin they can get their hand on right this second. Purely from a theoretical perspective, anything that can generate power at lower prices than the current market rate will be financially viable. With this past winters prices in Europe, it means literally anything. Even at times a diesel generator from your local hardware store would be a good idea (~.60 EUR per kWh). But these prices won't last, in a few years we will be already back down to manageable price fluctuations. It's pretty easy to see though that if battery based grid storage is going to be a big thing, it is not going to be EV batteries. The chemistry used in them is not optimized for life cycles (at least currently). LFP chemistry batteris that are in some Teslas has bettery cycle duration. Sodium Ion batteries will most likely be the choice for grid-scale deployment if they can be commercialized.

  That's actually not true. Let's say your calculation of ~100 per MWh for batteries is correct, we've seen that the wholesale prices were a multiple of that basically this whole year. Nuclear is above that price. I don't think anybody is seriously planning to use car batteries as the backbone of the grid, but as one of the last resorts yes. It makes sense for everybody.
