The DOE SunShot CSP Program aims to significantly increase operating temperatures, efficiency and lifetime, while lowering cost of receivers. The SunShot Initiative funds research and development (R&D) on receiver systems and related aspects within the industry, national laboratories and universities to achieve the following technical targets of receiver subsystems:

  • Heat transfer fluid exit temperature from the receiver > 650°C
  • Thermal efficiency > 90%
  • Lifetime > 10,000 cycles
  • Cost < $150/kWth

The R&D approaches toward these goals are broadly in the areas of:

  • developing fundamentally new receiver designs
  • developing novel solar selective coatings
  • exploring high temperature receiver corrosion and heat transfer fluid stability.
