If you are an energy provider dealing with high costs of solar thermal plants — this project developed a particle-driven system that reduces the Levelized Cost of Energy (LCOE) by 5.4%. It allows for high-efficiency conversion cycles at 750°C.
High-Efficiency Solar Thermal Power Plant Using Fluidized Particle Technology
Imagine using tiny sand-like particles instead of liquid salts to capture and store the sun's heat. These particles can get much hotter, allowing the system to generate electricity more efficiently. It's like upgrading a home heater to an industrial furnace to get more power from the same amount of fuel.
What needed solving
Current Concentrated Solar Power (CSP) using molten salts is limited by temperature and efficiency, leading to higher electricity costs. There is a need for a more reliable, higher-temperature medium to lower the LCOE.
What was built
A MW-scale prototype including a 2 MWth fluidized bed solar receiver, a 300 kW particle superheater, a 1.2 MWe turbine, and a 100m vertical transport system.
Who needs this
Who can put this to work
If you are a factory owner dealing with the need for high-temperature industrial heat — this project developed a MW-scale prototype that can provide heat for industrial production. It utilizes a 2 MWth solar receiver to generate sustainable high-grade heat.
If you are a developer dealing with the intermittency of solar PV — this project developed a hybrid CSP-PV concept. This combination increases sun-to-power efficiency by 9% compared to standard molten salt technology.
