I still believe there is potential for hydrogen/ammonia/methane fuel to be a seasonal storage mechanism. Battery technology does not seem capable of offering grid scale storage for the entirety of Winter. While the solar->fuel->electricity conversion takes huge efficiency hits, for “free” renewable energy, it can still pencil out as economical. Plus, it is feasible today without unobtanium (but not currently cost competitive vs fossil fuels)

> seasonal storage mechanism

Is this even needed? With solar, wind, etc storing more than a few days worth of energy seems very wasteful.

Available solar energy is significantly lower in winter. Additionally, heating typically requires more energy than cooling, so it is a double whammy. Solar alone cannot generate sufficient power without ludicrous over provisioning which would be wasted the majority of the year.
