The Heat Vault Company

About

The Heat Vault Company provides a solution to both short-term and long-term energy storage: not just for minutes, but up to decades. Stored not as electricity, but as heat. We can store waste heat, or low/no cost electricity. We can mitigate the intermittency of renewables such as wind and solar. And we can deliver heat, or cooling; electricity or hydrogen. For district heating, as a back-up supply or coupled to the grid or a micro-grid.
