Yes, I was not proposing such system as a large scale solution for the coming winter. It would be prudent to keep our nuclear reactors running for now.

As always, There is No Silver Bullet™.

Nuclear is not the perfect solution. It cannot be powered on and off on short notice, which would be useful for complementation of solar and wind that have high power output, but also sudden slumps. Ironically, the ideal companion for renewables would be gas...

Lithium batteries could compensate short outages, but don't have enough (feasable) capacity for long seasonal shortages.

Enter Power to Gas. Hydrogen can be a good tool in that area.

A commerically available hydrogen storage system (that is in high demand even despite its price point) will definitely accelerate innovation very effectively. I think this tool will be available quite soon for mere mortals.

I'd add that it's also prudent to build new nuclear reactors now. The tech exists and there is a very clear lack of mostly plannable power supply in many countries/regions.

The tech for building reliable, safe, affordable, large-scale hydrogen "batteries" isn't here yet.

New nuclear reactors are also not here yet. They might become ready in 8+ years if started now.

So the solution is simple. Nuclear has its place. Power2Gas too. Build and invest in both. And in the meantime, use what we have without ideolgical eye patches.
