The lime stores 0,32KWh / kg of CaO (ie 320KWh / m3 but 900 ° C of concentrated solar energy is required.
Gypsum or plaster stores much less, but at lower T 163 ° C !!
sea salt too.
Calcium chloride too.

The number of bodies storing energy as well is huge with all the possibilities and temperatures.

At human temperature less than 100 ° C is stored at max 70 at 100 KWh / m3
The earth (clay, rock, etc.) free under our feet at + 36 ° C above the ambient stores 10KWh / m3 (between 20 ° C and 56 ° C).
Paraffin at 60 ° C 60KWh / m3 approximately (dodecanoid).
Overall view of the capacity possibilities 0,1KWh / L = 100KWh / m3 depending on the temperature:
