Decade-long growth in concentrating solar power (CSP) deployment has resulted in over 6,000 MW of operational capacity today. In the past several years, the first utility-scale central receiver CSP systems entered commercial operation, including many with integrated thermal energy storage (TES) capability. Next-generation central receiver systems are targeting operating temperatures above 700°C and use of a closed Brayton power cycle with supercritical CO2 (sCO2) as the working fluid. These systems intend to deliver greater value through improved operating efficiency, dramatic cost reductions, and improved ability to provide grid benefits. EPRI examined international perspectives and preferences surrounding the future role, market, and technical capabilities for CSP. CSP experts from five countries with roles in utility resource planning, government energy policy and regulation, and solar project development participated in in-depth interviews that explored country-specific market needs and desired technology attributes and capabilities that would ensure market relevancy. Topics spanned current and future needs for baseload, intermediate, and peaking power; barriers and incentives for CSP; and support for next-generation central receiver (Gen3 CSP) technologies, among others. Additional insights and examples from the US and other countries are included where appropriate. [ABSTRACT FROM AUTHOR] |
