Advanced Nitrate Salt Central Receiver Power Plant
Commercial central receiver plant designs
Abengoa, under the Baseload CSP FOA, will demonstrate a 100-megawatt electrical (MWe) central receiver plant using nitrate salt as the receiver coolant, thermal storage medium, and heat transport fluid in the steam generator.
The plan is to operate the plant at full load for 6,400 hours each year using only solar energy. Abengoa is working to create a team of suppliers capable of deploying a commercially ready nitrate salt central receiver technology that can be competitive in the current power marketplace.
Abengoa is developing a new molten-salt power tower technology with a surround heliostat field. Key components include:
- A new high-temperature molten salt receiver based on a fossil boiler and heat exchanger design that will be more robust and more manufacturable
- A cermet, high-temperature, low-emissivity selective coating for central receivers that is stable when exposed to air
- An optimized surround heliostat field
- An optimized thermal storage, steam generator, and power cycle configuration based on dry cooling.
