Extra efficiency for Concentrated Solar Power plants via molten salt

The most important sources of renewable energy, the sun and the wind, are infinitely available – but they do depend on meteorological conditions, the time of day and the time of year. In the future, storage methods that smooth out these fluctuations will therefore play a decisive role in round-the-clock, [...]

Oxygen fix for high-temperature molten-salt degradation (and corrosion) at 620°C

The molten salt mixture deployed in today’s commercial CSP plants for thermal energy storage is liquid at 565°C and degrades at higher temperatures. Yet higher temperatures would increase thermal efficiency. So how can we develop a molten salt mix that can reach temperatures up to 620°C without degradation? And at [...]

Concentrated Solar Power Plants with Molten Salt Storage: Economic Aspects and Perspectives in the European Union

Concentrated solar power plants belong to the category of clean sources of renewable energy. The paper discusses the possibilities for the use of molten salts as storage in modern CSP plants. Besides increasing efficiency, it may also shift their area of application: thanks to increased controllability, they may now be [...]

Redstone Concentrated Solar Power Project On Track In South Africa
