According to Allied Mineral, it is working with the laboratory on the ENDURING project, which focuses on long-duration energy storage using heated particles.

“The process in development can collect excess electrical energy and convert it into thermal energy. With the help of refractories in a holding vessel, this thermal energy can be efficiently stored for days. When it is needed, the stored thermal energy will go through a heat exchange process and be converted back into electricity for use by commercial or residential customers,” the company said.
