The Heat Vault

  • Ultra-Long Duration, Utility scale underground energy store within naturally occurring rocks in the form of heat
  • Architecture of multiple deep boreholes some to input heat others to extract it
  • Input of energy from waste heat from facilities and waste or excess electricity from grid
  • Collects energy in off-peak and seasons with low energy demand at low cost
  • Stores energy for weeks, months, years or decades Output of energy at peak and seasons with high energy demand at acceptable price, decoupled from global hydrocarbon price volatility
  • Output can be as heat, cooling, electricity or green hydrogen Serves large infrastructure markets at GWh and TWh capacities
