Alsolen, a French manufacturer of concentrated solar power plants, will exhibit its thermodynamic power plant using Fresnel mirror technology at the upcoming World Future Energy Summit (WFES) trade show in Abu Dhabi.
WFEs and the International Water Summit (IWS) will be held in Abu Dhabi from January 19 to 22, 2015.
Alsolen’s product is a thermodynamic concentrated solar power (CSP) plant using Fresnel mirror technology to concentrate sunrays. Reflectors supporting self mechanically curved plane mirrors are lined up horizontally. By spinning simultaneously, the reflectors will concentrate sunlight into a line absorber containing thermal oil, the heat-transfer liquid used by Alsolen, a statement said.
This thermal oil is heated to 300C, and the produced heat is then transferred via an exchanger to an Organic Rankine Cycle featuring a turbo-alternator that produces electric power. This technique is enjoying increased popularity, for the mirrors actually cost less than those used in parabolic reflectors, according to the statement.
Alsolen concentrating solar power plants include thermal energy storage. Directly connected to the solar field, thermal storage will accumulate heat which is to be used later, in the evening, to continue producing energy.
The basic, sturdy design thus makes it possible to size the storage capacity so as to recover the energy for a few hours in the evening, or even for the entire night, the statement added.
