Electrolyzing excess energy to produce hydrogen is a good option. Sure, it is not that efficient but you can store hydrogen and it's a useful base ingredient for many industrial processes. And if you need electrical energy you just burn it in a gas-fired power plant.
- danhor 4y agoUnfortunately the equipment isn't cheap (though getting cheaper), so it only makes sense if it can run a significant portion (I've heard 25% in the coming decade for germany) of the time.

In the middle of Summer, there might already be 6 hours of underutilized solar (averaged with 0% excess in Winter). Given another 10 years of engineering and cost improvements, that does indeed sound a plausible use case.
