Thermal energy storage (TES) startup Rondo Energy has announced its second 100MWh project within a matter of weeks, at a brewery in Portugal.

What is claimed to be the world’s largest industrial thermal energy storage ‘heat battery’ has gone into operation in California, US.

Electrical and heat storage using specially nanocoated salt (NCS) could be economically competitive with pumped hydro, SaltX has said, with a large-scale demonstration facility inaugurated in Berlin, Germany.
