It's not that we couldn't use the excess energy to generate green fuel or green natural gas as storage that we need anyway for the foreseeable future for aviation, remaining ic engines.
Do we wiggle our magic fingers and generate gas out of nowhere ? Renewable gas accounts for about, at best, 10% of gas consumed in a year. As in, that's about as much renewable gas we could make. And it's not exactly an instantaneous process, so we would still be wasting energy. The best existing solution is storing that energy as water that we would pump up a basin, to be released later and used in a dam. That would work, if we did not need to flood areas where major cities are to make it work.

If we have excess (more or less free) electricity, i don't think we need magic fingers for this.
Hydro storage is quite expensive and difficult to build, for natural gas there is already a storage and distribution network in place. And it's quite easy tonstore for a long time.
