Why not sell something in tbis vein to households and then let them use cheap daytime electricity to charge it up and and then heat their homes at night.
(Or it could store “cold” during the summer)
Electricity is easy to move. Heat isn’t.

California has thousands of abandoned (orphaned) oil and gas wells, with more than 5,500 identified as "likely orphaned" in 2023, and an additional 70,000 economically marginal and idle wells that could become orphaned in the future.
Kern County, California has 75% of the state oil wells, and the largest solar farms. Even after the 70,000 wells are idled, Kern County will continue to produce enough oil to meet all internal demands in California, although the state no longer has the refining capacity or anywhere to lay off the oil.
