[en] This document is the White paper of the French thermodynamic solar industry. It presents: the solar resource and the different solar collector technologies, the worldwide production capacity, market and its expected growth, the French actors of the solar industry, the solar energy contribution to the national economy and the government support actions. Four technical data-sheets are attached in appendix and present: 1 - the operation principle of thermodynamic solar energy: concentrators, working fluids, power generation systems, heat storage systems and hybridization, 2 - the different types of solar thermal power plants, 3 - the development prospects of solar thermal energy: resources, development potential, present day applications, projects in progress, 4 - the solar thermal energy development in Europe and in the rest of the World (market, capacity versus technology, the Themis power plant)
[en] The thermal solar energy production is a promising and strongly growing sector. However, these technologies must be integrated to electric power systems, i.e. coupled with fossil-fired or biomass-fired plants, and the energy must be stored. This production can be either centralised or decentralised: this corresponds to different situations, different markets, different technologies and equipment (rows of mirrors to concentrate solar heat on a tube, linear Fresnel reflectors to concentrate solar heat on a tube, heliostats or mirrors which concentrate heat at the top of a tower, and parabolic disks which produce electricity with a Stirling gas engine at their focal point). This road-map focuses on electric power generation, and discusses key variables of the present market, proposes a vision for 2050, identifies objectives to be reached by 2015, and barriers to be removed, outlines the needs of demonstrators and their administrative framework.
