Yeah like the popular answers are eg - Hydrogen electrolyzers - Some deferrable industrial processes (or processes that can switch between fuels?) - Batteries ofc - EVs - etc etc Generally it seems like you have this tradeoff between saving $$ by running intermittently when energy is cheap, but not losing $$ from capital assets sitting idle. EVs are really in the sweet spot for short flexibility - their useful output doesn't change much whether they charge at 8PM or 1AM. Systems like smelters and electrolyzers are not at all as clear - they have enormous capital costs and their operators are likely not gonna enjoy letting them sit idle. It's interesting to imagine what kinds of systems could take advantage of this grid we now have where prices will be near-and-below-zero for long swaths of time during summer.. ideally also things that don't tax the transmission system, eg. could be placed close to production facilities..
