Technology roadmap: Solar thermal electricity
Concentrating solar plants (CSP) generate solar thermal electricity (STE) while producing no greenhouse gas emissions, so it could be a key technology for mitigating climate change. In addition, the flexibility of CSP plants enhances energy security. Unlike solar photovoltaic (PV) technologies, CSP plants use steam turbines, and thus can provide most needed ancillary services. Moreover, they can store thermal energy for later conversion to electricity…
