    Heat in general seems like the shittiest way to store electricity. The real application there is when you wanted heat anyway, like that cement plant (I think?) in Finland that keeps a tower superheated with renewables and then blows air through it into the kiln.

        It is, although capturing the CO2 that is generated by the chemical creation of dry concrete is probably an even harder problem in that specific case.
