High Temperature Hybrid Compressed Air Energy Storage (HTH-CAES)
HTH-CAES system utilizes a state of the art, high temperature energy storage solution.
This project designed a low-cost 74kW pilot High Temperature Hybrid Compressed Air Energy Storage (HTH-CAES) system that can efficiently store grid-level energy and release that energy when it is needed to meet peak demand, particularly for ancillary services and load following use-cases. This project documented and reported on the design, anticipated performance and lessons learned of the HTH-CAES system to increase knowledge and understanding of how these storage systems perform and the barriers to siting and operations.
The 74 kW system is designed to cost $938/kW and $156/kWh installed. Its designed to reach an efficiency goal of 85% and to last 15,000 cycles. At that level, cost could be 7 cents/kWh/cycle.
HTH-CAES produces no carbon emissions and utilizes a low-waste and environmentally friendly construction. This technology will reduce emissions of CO2, SO2, NOx, and CO by displacing natural gas fired peaker plants.
