Thermal Power Storage
World’s lowest-cost high-temperature heat storage
- A well-insulated, factory-made container
- Typically 6-20 hours operation; several days also available
- Less than 10% the cost of conventional batteries 150+ year proven technology
- No moving parts, 30+ year life
GROWING PV AND WIND DEPLOYMENT REQUIRES LONG DURATION STORAGE
Intermittent PV and wind often generate amounts of electricity that exceed demand. 100s of MW of batteries are being deployed to shift this excess to other times when demand for power exceeds capacity. Batteries are generally used to bridge this demand and supply gap for short periods, typically 30-60 minutes. But as more and more PV and wind are added to the system, the gap lengthens. Today, 4 hour-capacity batteries are increasingly used, yet the length of these gaps will continue to grow.
HOW DOES THERMAL STORAGE WORK
HeatStorE converts zero/low-cost excess power produced by PV, wind, or the grid to ultra-high-temperature heat (up to 1200℃/2200℉) and stores it for up to 20 hours or more. When power is needed again, typically at a high price, atmospheric-pressure air is circulated through the heat storage system. This ultra-hot air drives a proprietary turbine that converts the heat to electricity without combustion or emissions.
