I suppose... a "hydrogen battery" for solar? Build up formate (in solution? As a salt?) during the day, then burn it at night for electricity?

density is not really a critical factor for grid level or onsite energy storage, so it could be feasible in theory

As long as the electrodes / membranes for the conversion to electricity are stable and cheap as well. There's a big downside with PEM electrodes requiring platinum and with their longevity and energy density relative to capex.
