“…The thermal fluids used in the receiver are saturated or superheated steam, nitrate‐based molten salts and air. The most extensive precommercial experience has been collected by several European projects located in Spain at the premises of the PSA and the 10 MW Solar One and Solar Two plants in the US. At present water/steam and molten salts are the HTFs being selected for the first generation of commercial plants.…”

“…Production of superheated steam in the solar receiver has been demonstrated in several plants, such as Solar One, Eurelios, and CESA‐1, but operating experience showed critical problems related to the control of zones with dissimilar heat transfer coefficients like boilers and superheaters . Better results regarding absorber panel lifetime and controllability have been reported for saturated steam receivers.…”

Solar thermal concentrating solar power (CSP) plants, because of their capacityfor 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 Spain, 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 Andasol in Guadix, Spain, 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 Fresnel 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 (Gemasolar tower plant in Seville, Spain) 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 International Energy Agency in PTCs are linear-focus concentrating solar devices suitable for working in the 150-400 • C temperature range. 20 The current research with new thermal fluids intends to increase the operating temperature up Advanced Review 4 5 CONCLUSION AND OUTLOOKFrom the seventies to the nineties, the development of STE technologies remained restricted to a few FIGURE 9 Aerial view of Gemasolar plant, property of Torresol Energy C Torresol Energy, located in South Spain.

“…The aperture area of the Big Dish is more than a factor of 10 larger than collectors used in previous dish-Rankine plants such Solar Plant 1 (SP1) (Grasse et al, 1991) and the Solar Total Energy Project (STEP) (Stine and Heckes, 1987). The increased collector size corresponds to reduced number of collectors, lower network surface area, and lower network pipe material volume.…”
