It could be that the loss in heat storage can be compensated with heat pumps, powered by solar power, to keep the heat reservoir full.

I mean, the process is simple, clean, does not require special materials, provides lots of jobs and really seems long term.

The holy grail of energy storage will ultimately be a similar form (compressed gas, fuel generated with solar power, heat reservoirs, etc).

No matter how much you root for batteries, they will not provide grid scale power.

Batteries do, and will, provide grid scale power for short periods. Beyond that, they cost more than other methods. New battery chemistries might bring costs down, but it is hard to compete with tankage for cost per stored kWh.
