Concentrating solar power (CSP) technologies use mirrors to focus sun’s rays onto an absorber, where the photons are converted to heat that’s ultimately transferred to the working fluid of a turbine to generate electricity. The ability of CSP to incorporate simple and efficient thermal energy storage is a principal advantage of the technology. Widespread adoption of this technology calls for steep cost reductions, which is a primary challenge being addressed through several world-wide efforts. The talk will focus on the technical challenges and opportunities for innovation and cost reduction, for achieving cost-competitive concentrating solar power.
