Brayton Energy is building and testing a new solar receiver that uses supercritical carbon dioxide (s-CO2) as the heat-transfer fluid. The research team is designing the receiver to withstand higher operating temperatures and pressures than current state-of-the-art technology so that the device can enable higher efficiency systems.

Objectives 
  • Achieving an outlet temperature for the receiver working fluid (s-CO2) that is greater than or equal to 750°C
  • Maintaining high receiver efficiency
  • Retaining durability over the lifetime of the CSP plant
  • Significantly reducing the cost as compared to baseline receivers
