If the system scales based on the fluid, the $/kwh could get pretty low. Would be interesting what a MWh amount of heat storage would cost.

- petre 10y agoAssuming the 50% NaOH solution releases half the amount of heat released from dissolving dry sodium hydroxide in water, to store 1 MWh you would need about 6.5 tonnes of sodium hydroxide. The price for NaOH pearls 99% is 300-400$ per 1 metric tonne.
