Seasonal demand for heat is highly variable, creating technical and economic challenges for heat networks.
Heat Vault can store heat in Summer when demand and costs are low and supply heat over the four months of Winter, or other seasons, when demand is higher.
The energy transition requires solar and wind electricity to be 60% of mix by 2050, which needs sizeable storage to manage intermittency.
Heat Vault can create vast storage as heat by utilising waste electricity and waste heat during periods of excess or at low cost in off peak hours, storing it for days to years and supplying it to suit demand for heat or electricity. Its use can eliminate curtailment.
Geothermal resources are more commonly discovered in active zones or at great depth, where temperatures are high enough to be useful for electricity or heat supply.
Heat Vault can store excess heat from deep geothermal and take mid-level geothermal energy at lower temperature, boost it to high temperature and store it, making geothermal achievable in many locations without risk of expensive deeper drilling.
A VAULT FOR ALL SEASONS
Global industrial waste heat is significant. Key industries are also major heat energy consumers at scale and for a wide range of temperature.
Heat Vault can receive waste heat from industry at low to moderate temperatures, store it, reprocess it for heat supply for space or process heating at low temperatures or heat consuming processes at high temperatures.
All forms of nuclear fission or fusion plant generate significant quantities of heat by design or as waste product from reactor coolant systems.
Direct low temperature district heating or higher temperature process heat from isolated nuclear plants may not be dispatchable to meet demand but could be stored within Heat Vault at scale for later re-use.
Fossil fuel-fired electricity generating utilities are in transition and require cleaner alternatives for continued operations of assets and infrastructure.
Rather than partial decarbonisation using gas or biomass feedstocks, Heat Vault coupled with electricity generating turbine technology can achieve full decarbonisation at lower cost than other options and with marked reduction or elimination of feedstocks while retaining generating assets and infrastructure.
MANAGING HEAT SUPPLY & DEMAND
Locations for excess heat do not coincide with areas of heat or cool demand
Storing excess heat for supply to heat networks can create a circular economy
