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
