Electricity is already priced negatively in some markets at some times of the day because of the mismatch between demand and supply from intermittent wind and solar generation. The trick here is how to design an energy storage solution that can exploit that mismatch. It’s the ultimate buy-low sell-high opportunity.

The trick is to design energy-intensive industries so that they can use DC power for a few hours each day and to site them at the PV/wind farms.

This is already happening with desalination and hydrogen production via electrolysis, and hydrocarbon production (for carbon-neutral transport fuel) is being piloted too. Future likely applications include electrolytic refining of iron ore to the metal. Cheap electricity is going to enable new industries we haven't thought of yet.

"P2X" is the abbreviation to look out for.
