Molten Salt Parabolic Trough Technology

Molten salt heat transfer fluids represent a challenging, but potentially disruptive, next step forward for parabolic trough technology.  By circulating molten salts inside the parabolic trough receivers, future parabolic trough solar fields can harness the considerable benefits of direct thermal energy storage and working temperatures of up to 560°C (1040°F).  

 

We are now testing innovative strategies and advanced components designed to reduce the cost and risk of transitioning to molten salt heat transfer fluid in future parabolic trough solar fields.  Success in this transition will establish a new technology pathway for next-generation CSP installations like our Dispatchable Solar Power plant, as well as for other solar thermal applications that directly displace fossil-fired sources of heat.
