SunShot Initiative

Parabolic Trough

DOE funds solar research and development (R&D) in parabolic trough systems as one of four concentrating solar power (CSP) technologies aiming to meet the goals of the SunShot Initiative. Parabolic troughs, which are a type of linear concentrator, are the most mature CSP technology with over 500 megawatts (MW) operating worldwide.

Parabolic trough technology is currently the lowest-cost CSP option for electricity production; however, unsubsidized electricity from troughs still costs about twice that from conventional sources. The SunShot Initiative funds R&D on parabolic trough systems and related aspects within the industry, national laboratories and universities to meet the SunShot goals. An extensive set of core capabilities at the national laboratories support the R&D endeavors.
