More Information

Eligible Uses

The term “clean energy project” ​means a project that demonstrates one or more of the following technologies:​

  • Solar
  • Micro-grids​
  • Geothermal​
  • Direct air capture​
  • Fossil-fueled electricity generation with carbon ​capture, utilization, and sequestration
  • Energy storage, including pumped storage hydropower and ​compressed air storage
  • Advanced nuclear technologies


In selecting clean energy projects for participation in the program, the Secretary shall prioritize clean energy projects that will—​

  • be carried out in a location where the greatest number of jobs can be created from the successful demonstration of the clean energy project;
  • provide the greatest net impact in avoiding or reducing greenhouse gas emissions;​
  • provide the greatest domestic job creation (both directly and indirectly) during the implementation of the clean energy project;​
  • provide the greatest job creation and economic development in the vicinity of the clean energy project, particularly—​in economically distressed areas; and ​with respect to dislocated workers who were previously employed in manufacturing, coal power plants, or coal mining;​
  • have the greatest potential for technological innovation and commercial deployment; ​
  • have the lowest levelized cost of generated or stored energy;​
  • have the lowest rate of greenhouse gas emissions per unit of electricity generated or stored; and​
  • have the shortest project time from permitting to completion.​
