Building upon the successful outcomes of the 2012 SunShot CSP R&D FOA, the CSP: Advanced Projects Offering Low LCOE Opportunities FOA seeks to further CSP system technologies by soliciting transformative projects for all of the components of a CSP plant. These innovative projects will seek to meet the targets set out in the SunShot Vision Study, enabling CSP to be cost-competitive with conventional forms of electric power generation. Projects will address challenges in every technical system of the plant, including solar collectors, receivers and heat transfer fluids, thermal energy storage, power cycles, as well as operations and maintenance, which have not been previously specifically targeted by CSP FOAs.
