Power2gas+solar/wind produced energy is a lot more expensive than natural gas and requires solar/wind to routinely overproduce.
...hence why there isnt much of it. It either requires subsidies or for natural gas to be taxed more.
Windless night produced electricity from stored solar energy via windgas is still cheaper than nuclear power produced on sunny, windy days though: https://theecologist.org/2016/feb/17/wind-power-windgas-chea...
Solar is always producing, at some percentage (may be very a very low percentage) of full capacity. So, we want it to routinely overproduce. That’ll also cut the days that we need to dip into storage.

Subsidies are hard to calculate anyway. For example almost all fossil fuels get a pair of massive subsidies; we let them dump their carbon into the air for free instead of charging for it, and we build and man a bunch of aircraft carriers to go around defending the shipping lanes that it gets sent through.
