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…

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…

A way of reducing polltion is the use of nanoparticles of gold in catalytic converters. The carbon monoxyde is completekly oxidized by the gold.

The research on the use of gold nanoparticles in car catalytic mufflers tries to reduce pollution. Nowadays muffles do not work at low temperature. This film shows the method used to prepare the gold catalysis.

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.

It is essential to understand the ultimate chemistry which happens in catalytic converters in order to filter the toxic gazes produced by the engines and transform them into harmless residues. With Frédéric Thibault-Starzyk (CNRS) from the LCS (Laboratory for catalysis and spectrochemistry).

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.

The use of fossil fuels takes part in the increase of greenhouse gases, and influences on the climate. Transports, especially cars, play an important part in this pollution. Thinking about the place of clean energies in tomorrow energetic choices is getting more and more necessary. This film gives an overview of the French research on hydrogen energy, applied to transports. It shows obstacles to the emergence of a mass market for hydrogen cars, solutions that loom in the laboratories and life…

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.
