DOE Selects 6 Projects to Develop Tech for Thermal Efficiency at Combined-Cycle Power Plants

investment money exchangeThe Energy Department‘s National Energy Technology Laboratory will invest $30 million in six selected Phase 2 projects to help develop technologies for gas turbine components and supercritical carbon dioxide power cycles.

DOE said Wednesday it seeks technologies that work to help combined-cycle power plants meet a target thermal efficiency rating of 65 percent from its current efficiency rating of 61 percent.

The department added that the higher efficiency will come from sCO2 power cycles producing higher outputs in a smaller package, which in turn potentially cuts the cost of electricity.

The six selected Phase 2 projects out of the 11 Phase 1 awards are:

  • Rotating Detonation Combustion for Gas Turbines
  • Development of Low-Leakage Seals for Utility-Scale sCO2 Turbines
  • Cooled High-Temperature Ceramic Matrix Composite Nozzles for Gas Turbines for 65 Percent Efficiency
  • Advanced Multi-Tube Mixer Combustion for 65 Percent Efficiency
  • Ceramic Matrix Composite Advanced Transition for 65 Percent Combined-Cycle Efficiency
  • High-Inlet Temperature Combustor for Direct-Fired Supercritical Oxy-combustion

Participants involved in the six Phase II projects are:

  • Aerojet Rocketdyne
  • Clemson University
  • COI Ceramics
  • Duke Energy
  • Florida Turbine Technologies
  • GE Global Research
  • GE Power
  • Georgia Institute of Technology
  • Purdue University
  • Siemens
  • Southwest Research Institute
  • Thar Energy
  • University of Alabama
  • University of Central Florida
  • University of Michigan
