Could it be that water contains an almost inexhaustible source of energy, and above all, that it is within everyone's reach? And what if hydrogen would redefine the contours of our future? Faced with global climate change, the quantities of CO2 from industry and transportation that are released into the atmosphere are widely blamed. In order for humanity and the planet to imagine a viable future by 2100, it is urgent to find a sustainable alternative to our fossil fuels. And in this quest for…

Alors que les piles à hydrogène se répandent de plus en plus dans le secteur de l'énergie et des transports, de nombreux travaux sont menés pour les rendre plus performantes et compétitives. Ceux de Daniel Hissel, professeur à l'université de Franche-Comté et membre du laboratoire FEMTO-ST, font référence. Son objectif : intégrer ces convertisseurs d'énergie dans de nouvelles applications et concevoir des outils pour leur diagnostic en temps réel. « Nos…

Sophie Brouard, Daniel Hissel, Arnaud Landragin and Franck Molina are the CNRS 2020 Innovation Medallists. Since 2011, the CNRS Innovation Medal rewards figures whose exceptional research work has led to groundbreaking innovation in the technological, economic, therapeutic, and social fields. The career paths of the four CNRS 2020 Innovation medallists illustrate the quality, variety, and wealth of research conducted at the CNRS, as well as the different ways of…

What if we could power our vehicles with powdered metals? Aluminum and magnesium have the same energy density as fossil fuels and the waste - metal oxydes - can be recycled with concentrated solar energy.

With the short-term depletion of fossil fuels (oil, natural gas, coal, etc...) and the deterioration of our environment looming, the use of renewable power sources is becoming essential. The energy transition has thus become one of the major technological and scientific challenges of the 21st century, with non-carbon renewable power sources representing a major alternative to fossil fuels. However, their exceptional potential is strongly offset by the storage problems caused by the intermittent…

Batteries are devices able to transform chemical energies into electric energies. Actual research allows to glimpse an amelioration of the stocking capacity of a scale factor of two even a scale factor of three, in a decade or two. In this short film, Jean-Marie Tarascon from the “Laboratory for reactivity and solids chemistry” (LRCS) explains these new techniques.

Within the frame of the sustainable development, researchers try to develop batteries inspired by the living chemistry. In this short film, Jean-Marie Tarascon from the LRCS (Laboratory for reactivity and solids chemistry) describes these researches.

In urban transport systems, an ideal answer to chemical and noise pollution issues lies in the deployment of electric vehicles; they can be used in organisations? car fleets, bus lines, and also in self-service rental systems, those individual means of public transport representing the missing link between urban public transport and long-distance car journeys.

As chemical and sound pollution increases, the electric vehicle becomes a solution to urban transportation problems. In La Rochelle and Bordeaux, the city government has set an example. The idea comes in various forms - scooters, river boats, and delivery services. Industry and research organizations are actively involved. CNRS laboratories are carrying out research on battery components. The use of electric vehicles of many kinds is becoming widespread.

In June 1928, Jules-Louis Breton and personalities from the Ministry of Agriculture, Colonies, Commerce, Public Instruction and the Automobile Club de France opened the forestry exhibition organised in the Versailles state forest. This exhibition, which ended in July, was the occasion for a competition on wood charring, mechanical wood exploitation, gasifiers, and fuels for gasifiers and domestic uses.
