Summary
Heating and cooling account for half of the global energy consumption. The availability of clean, decarbonized renewables is a challenge when developing sustainable energy solutions. In the rock beneath the Earth's crust lays a sustainable solution to the problem.
Heat Vault is a patented solution that allows recovery of waste heat from industry and excess electricity from solar and wind power. The waste heat is used to heat up large volumes of rocks to high temperatures via multitude of deep boreholes. The heat can be stored for long periods, up to years, and then be recovered when needed as district heating, industrial process heating and even for electricity generation by turbine technology.
