Abstract

Direct steam generation (DSG) technology is a proven option for future cost reduction of concentrating solar thermal power plants in comparison with other concentrating solar technologies. The integration of thermal energy storage (TES) in a solar power plant offers an important benefit compared to other alternative power generation systems because it enables an efficient integration in the electricity grid and provides flexibility in the operation. However, the two-phase heat transfer fluid in DSG solar plants is a major challenge, and innovative TES concepts and new integration ...
