AbstractThe National Solar Mission launched by the Government of India promotes the deployment of 20,000 GW of solar power by 2022. In this initiative CSP plays a significant role. Solar thermal power generation opportunities in India are huge. SunBorne Energy in partnership with the Ministry of New and Renewable Energy (MNRE), Government of India, is developing solar power tower technology within the framework of the R&D project CRISPTower (Collaborative Research Initiative in Solar Power Tower). The project is being carried out in cooperation with IMDEA Energy, Spain and the Clean Energy Research Center (CERC), University of South Florida (USA). A 1MWth solar power system is currently being installed at the Solar Energy Center at Delhi,India (28.425̊ Latitude). The project envisages the use of atmospheric air as the working fluid with an exit temperature from an open volumetric metallic porous receiver of about 600̊C. A new carousel-type heliostat design with 150m2 mirror surface area is incorporated in the system. The thermal storage system is based on a packed bed of rocks, primarily consisting of metallic oxides as sensible storage medium.
