Project Innovation + Advantages:
The Brayton Energy team will develop a key component to enable a cost-competitive Laughlin-Brayton battery energy storage system that combines thermal storage and innovative turbomachinery to generate power. When the system is charging, an electrically driven heat pump will accumulate thermal energy in a high temperature thermal energy storage medium. During discharge, electricity is produced by heating a gas using the stored thermal energy and sending it through the generation turbine that drives an electric generator. Brayton Energys innovation lies in its reversing, counter-rotating turbine design, in which each turbomachinery stage is designed to act as both as a compressor and turbine, alternating between charging and discharging cycles. This approach greatly simplifies the Laughlin-Brayton battery system, improves its efficiency and operability, and reduces the capital cost. |
