Which car is the most ecological?

While the new thermal vehicles will be prohibited for sale in the European Union in 2035, France aims To achieve carbon neutrality from here 2050 to respect Paris1 Paris agreements. CET objective which is part of the energy transition implies the use of new mobility energies as electric and hydrogen who have property different. Revision of characteristics of two types of energy At the ecological level.

Taking into account 100 watts of electricity produced by a renewable source such as a wind turbineelectric present several advantages And It appears clearly AS more profitable. Pto nourish THE fuel cell A vehicle operating in hydrogenenergy departure duty Indeed To be converted into hydrogen through electrolysis Before compressed and refrigerated. Hydrogen is in turn converted into electricity once inside the vehicle And in the end, only 38 ofTTS They are used on the initial 100 watts (or energy efficiency about 35%). Opposite, The electric car View a product global About 80% With only 10 watts used by loading and downloading the battery And 5 Watt to move the vehicle, 5 others watt being lost during transport to the network. To the extent that hydrogen production requires double electricity To circulate a vehicle With this type of energy, A car Equipped with an engine Electric is destined more ecological.

In terms of carbon dioxide emissions (CO2), L‘ Life cycle of a Vnight table – Production, use, recycling and end of life – it proves it hydrogen East more ecological What electric. Between 130 and 230 g of CO2/Km, LAnd a pledge of carbon hydrogen car Remain better than that of the electric car (between 160 and 250 g of CO2/km) And Above all combustion car (between 180 and 270 g of CO2/km). This difference is explained in particular from the Production of batteries as well Lithium extraction and rare metals necessary to their productionTwo steps particularly Energy gourmet. If the hydrogen car does not emit greenhouse – like the electric car – or polluting emissions as it rollsThis does not mean that it is ecological, clean or green. As for a thermal vehicle, it really has it impacts environmental connected to the car production, the fuel cell and hydrogen. When electricity is produced with wind, solar (renewable energy) or nuclear, the carbon imprint remains Today Byarn more favorable TO carSort electricSort. In one case as in the other, Life cycle analysis So it depends on «Electric mixture» used.

ProduceBlue hydrogen methane

By transforming methane (natural gas), producers produce «Gray» hydrogenalso called «Bleu» (90% of global hydrogen) whenAND Carbon capture systemEy is added. Technology Geological seizure constitutes a solution that it should allow almost 15% of to archive by 2030The programs of CO2 throughout the planet.

THE‘green hydrogen Product without gas ha greenhouse

Use electricity «Bas Carbone » To transform water molecules into hydrogen molecules (chemical reaction made possible thanks toelectrolysis)produce manufacturers From «Green» hydrogen which does not generate greenhouse gases, both during its production and during its use.

With a cost of the cost From 2 to 7 € For 100 km, the electric car is scheduled less expensive that the hydrogen car (from 9 to 12 € per 100 km). It also requires less maintenance, a benefit for electric vehicles Also a network of charging stations, whose installation remains less expensive than the distribution of hydrogen stations. Only experiencesHydrogen hicole with great autonomy such as trucks and buses It remains advantageous, the weight of the electric battery OneAnt a Brake on profitability.
