  • Because electricity is more difficult to store than to transport, electric networks have been conceived and exploited at anytime to maintain the balance between supply and demand.  Apart from applications on a remote spot or on an island, the electrochemical storage of energy is still marginally used.  However, for 10 years, new Na-S and Li-ion battery technologies, with high performances and adequate life spans, have been used to handle the intermittent renewable energies i.e. photovoltaic and Aeolian, and to offer the electric networks new possibilities.

  • The car industry business as it is today must change because of the decrease in fossil energies, and pollution problems, all of which are increasing due to the rise in population.  Facing such a scenario, in a few years time our gas or diesel vehicles will be progressively replaced by electric vehicles that will be more and more publicized and highly valued. Such a broad acceptance of EV will be facilitated by the development of  more performing batteries.

  • Storage and production of electric energy are two inseparable parts to successfully ensure an energetic paradigm change;  although the meaning of ‘paradigm’ seems to be presently tarnished, its true meaning reappears when used in this energetic context.  It’s become an important and strategic challenge for our industry and our country as stressed by the Grenelle de l’environnement.

    For several centuries we have been using our Planet’s resources without giving a second thought about their limited quantity.  Even though the stock is diminishing and our needs are increasing we still carry on using it in spite of it forthcoming end. To answer this energy demand, which can only rise due to both our population and life style increase, it has become more than urgent, and in the long term vital, to be able to efficiently exploit/collect new energy sources as well as to store them efficiently.  

  • Energy supplying and handling is more than ever central to our daily concerns and represents a major socio-economic priority.  The future electric energy storage for large volume applications together with electric transportation and network applications will be inextricably linked to energy sources alternative to fossil fuels (oil, gas and coal).
