Revolutionizing Solar Power Generation: The Falling Particle Receiver

TLDRSandia National Laboratories has developed the world's first continuously recirculating high-temperature falling particle receiver for concentrating solar power, which allows for higher concentrations, increased efficiency, and the use of commercially available particles. The falling particle receiver enables cheap and efficient energy storage for 24/7 electricity production and can be retrofitted onto existing systems.

Key insights

🌞The falling particle receiver allows for much higher concentrations of solar power, with over a thousand times the sun's irradiance.

🌡️Ceramic particles, commonly used in the oil and gas industry, are heated directly in the receiver, reaching temperatures well over a thousand degrees Celsius.

🔄The particles can be stored to generate heat or electricity at different times, or recirculated through the system for even higher temperatures.

💡The falling particle receiver opens up new possibilities for thermochemical storage, industrial process heat, and water treatment.

🔋Achieving 90% thermal efficiency with the falling particle receiver contributes to the Department of Energy's SunShot initiative to make solar energy cost competitive.
