Sodium Nitrate for Concentrated Solar Power

Application: Thermal storage


Sustainability performance:

  • Environmental friendly mix of sodium and potassium nitrate used as energy storage medium in Concentrated Solar Power plants.
  • In even more effective high temperatures CSP plants (> 550 ºC), it is used in addition as Heat Transfer Fluid (HTF).
  • Enables supply of green solar electricity also during the night and under storm or cloudy weather.
  • Highest product quality allows maintenance-free operation in a closed loop production process without residues.
  • Materials are easy to use.
