Supercritical CO2 Power Plant Granted $80M from DOE

By Editors of Power Engineering

The U.S. Department of Energy has award $80 million to a team with plans to design, build and operate a 10-MW supercritical CO2 power plant.

The group, which includes the Gas Technology Institute, Southwest Research Institute and GE Global Research, hope to advance the technological development of Brayton power cycles, address research and development needs of component vendors and support risk reduction and commercialization.

Brayton power cycles use supercritical CO2 as the working fluid within high-power-density turbomachinery. When built, the plant will operate at a turbine inlet temperature of at least 700 degrees Celsius.

The group feels turbomachinery power cycles using supercritical CO2 will reach higher thermal efficiencies than conventional techniques, making the technology an attractive alternative for power generation.

The actual plant will be constructed at Southwest Research Institute’s San Antonio, Texas campus.
