Another exciting development in energy storage... salt batteries are a really promising area, and I am very excited for this area of technology to take off. I am very interested in other technologies developing in this area too, like this Finnish tech for sand.

'Energy storage' is too often understood to comprise only electricity storage.

The heating sector needs to be electrified anyway, so why not use #HeatPumps to convert wind&solar power to heat (or resistors for 'excess' power), and store it in thermal #SeasonalHeatStorage like boreholes, caverns, pits or aquifiers?

That's cheaper in regions, where space heating represents a significant share of energy consumption and #districtHeating is used.
