[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.
[en] Energy storage (electric and thermal storage) is a global industrial sector that is gaining in power and leading to numerous agreements between industrialists and research bodies. In France, this dynamic meets the 2020 political and social objectives set by the Grenelle de l'Environnement in addition to the 2050 'Factor 4' objectives It must enable the renewable energy- electrical and thermal energy - development objectives to be reached by integrating this increasing production into the French energy mix in a similar manner to that of rechargeable hybrid and electric vehicles, and finally, it must generate as much value as possible for the energy produced. This benefits from the significant technological progress made in the field of materials, electrochemical techniques (for batteries), power electronics and information and communication technology. Electrical energy storage involves, on the one hand, stationary systems - for dedicated sites which provide support to power grids and renewable energy production sites - and, on the other hand, embedded systems - small-scale storage means integrated into a mobile system, in particular within rechargeable hybrid and electric vehicles. Heat storage essentially involves stationary systems used in the building sector. Embedded heat storage and distribution systems are also studied within the scope of this road-map, produced with a panel of experts from research bodies and companies, including both storage system manufacturers and users.
