Ces deux Hyundai ix35 FCEV sont en tout cas les premières voitures de série à hydrogène à être immatriculées en France. Avec 1000 unités prévues par Hyundai dans un premier temps, cela reste certes de la petite série, mais c’est de la série !

Toyota et Honda viennent par exemple de montrer au salon de Tokyo les voitures qu’ils comptent produire en série en 2015. Tous les constructeurs sont dans cette logique. Ceux qui sont moins avancés visent 2017.
Rappel des inconvénients (majeurs) des piles à combustible à hydrogène :
The dirty secrets of clean cars

First, there is the problem of providing the hydrogen fuel, along with the infrastructure for transporting it to garages across the country. […] Another study suggests making hydrogen dispensers as common as petrol pumps would cost America the small sum of half a trillion dollars.
Then there is the question of where the hydrogen comes from. At present, industrial hydrogen (…) is produced by reforming natural gas with steam. This is not a particularly clean process. According to the National Renewable Energy Laboratory, a federal facility in Colorado, producing a kilogram of hydrogen by steam reformation generates 11.9 kilograms of carbon dioxide. As the Honda Clarity could travel 68 miles (109km) on a kilogram of hydrogen, it would cause 175 grams of carbon dioxide to be dumped into the atmosphere for every mile it was driven.
By way of comparison, Volkswagen’s small diesel cars produce 145 grams per mile. On that reckoning, even petrol-electric hybrids like the Toyota Prius, which produces 167 grams per mile, are cleaner than the fuel-celled Clarity. Admittedly, fossil fuels also produce carbon emissions while being dug out of the ground, refined and transported to the pump. But burning hydrocarbons in internal-combustion engines is becoming cleaner all the time. When measured on a well-to-wheels basis, the steadily declining emission levels of conventional vehicles is putting the squeeze on so-called ZEVs [zero-emission vehicles].
