Solar thermal concentrating solar power ( CSP ) plants, because of their capacity for large‐scale generation of electricity and the possible integration of thermal storage devices and hybridization with backup fossil fuels, are meant to supply a significant part of the demand in countries of the solar belt. Nowadays, the market penetration of solar thermal electricity is steeply increasing, with commercial projects in S pain, USA , and other countries, being the most promising technology to follow the pathway of wind and photovoltaics to reach the goals for renewable energy implementation in 2020 and 2050. In the first commercial projects involving parabolic‐trough technology, some improvements are being introduced like the use of large molten‐salt heat storage systems able to provide high degrees of dispatchability to the operation of the plant, like the plants A ndasol in G uadix, S pain, with 7.5 h of nominal storage, or the use of direct steam generation loops to replace thermal oil at the solar field. In the near future, the research and innovation being conducted within the field of linear F resnel collectors may lead to high temperature systems able to operate up to 500°C and produce cost‐effective superheated steam. Central receiver systems are opening the field to new thermal fluids like molten salts ( G emasolar tower plant in S eville, S pain) with more than 14 h of nominal storage and air, and new solar receivers like volumetric absorbers, allowing operation at temperatures above 1000°C. All these factors can lead to electricity generation cost reduction of CSP plants by 30–40% for the period 2010–2020, according to public roadmaps and cost analysis made by the I nternational E nergy A gency in 2010.
