Innovations in thermal energy storage is seeing significant action. And here’s one from Toshiba & Marubeni.

A pilot project that these two Japanese giants have developed uses materials such as crushed stone, bricks, molten salt, concrete, and ceramics to store the heat and appears that it can store heat at temperatures above 700 C.

That’s interesting!
