Hydrogen engines how does it work

The answer differs between manufacturers. Firstly, recharging from a standard electric terminal to supply the lithium-ion battery an option facilitated by the number of accessible charging stations.

Secondly, refueling at a hydrogen station to refill the gas tank takes just a few minutes — during the day, for example, when the driver needs to extend their trip. Of course, hydrogen, highly-pressurized in its tank, is a volatile and flammable element. In case the fuel cell overheats or is removed, the hydrogen is dispersed and released in less than a minute. Before going into circulation, hydrogen cars must adhere to particularly strict European regulations. Kangoo Z. For over twenty years, technologies that use dihydrogen have been tested and approved on numerous occasions, often under extreme conditions space engineering, submarines, construction machinery.

Today, thanks to the experience accumulated from the pioneering Kangoo Z. Hydrogen since , Renault Group is going even further, announcing a partnership with the renowned world leader in fuel cells, Plug Power, who have rolled out over 40, fuel cell systems to date. The resulting Innovation Center will not only place its partners at the cutting edge of research and development, manufacturing, and the commercialization of hydrogen vehicles, but also at the forefront of related services charging infrastructures, hydrogen supply, etc.

While these two technologies give the impression of being diametrically opposed, they are actually complementary mobility modes. On a light utility vehicle with a high payload capacity, hydrogen is particularly interesting.

Even though the tank used to store the gas is large, its weight remains reasonable. Electric vehicles equipped only with lithium-ion batteries are intended for all types of driver and use, from short trips around town to longer journeys. But when the battery is empty, the only solution is to recharge on the electricity grid. The electric-only vehicle takes longer to charge than its hydrogen counterpart, but there are more charging stations available, both in private and public locations.

Parking can be easily combined with charging the vehicle. Both electric and hydrogen are therefore complementary technologies designed to provide sustainable mobility suitable for all types of use. Hydrogen refueling stations are expanding progressively throughout Europe. In , for example, there are around stations in France, with the objective of reaching stations by There are operational stations in Europe, with being rolled out.

To support this developing infrastructure, several European countries have introduced incentivizing policies to promote the technology: like Germany, which has just allocated a budget of million euros to the sector, and France, which finances the purchase of a hydrogen vehicle by up to 16, euros.

The arrival of the first mass-produced hydrogen electric cars, including professional vehicles currently refueled on company premises, will help accelerate the development of infrastructure, promising a bright future for hydrogen technology.

And with a wide-ranging representation from companies and sectors, there are four different workstreams taking place:. Combined Heat and Power CHP : a project to install a hydrogen fuel cell stack that will power alocal public buildings. Forklift trucks: a trial of fuel cell powered forklift trucks with an aim to roll out 75 in total. And what about the disadvantages of hydrogen cars?

So watch out for hydrogen technology. It could be coming to a street — or airport — near you. How does it work? First, hydrogen stored in a tank that is thick-walled and crash-tested, and usually under the rear seat is mixed with air and pumped into the fuel cell. Inside the cell, a chemical reaction extracts electrons from the hydrogen. The leftover hydrogen protons move across the cell and combine with oxygen from the air to produce water.

Meanwhile the electrons create electricity, which charges a small storage battery used to power an electric drivetrain just like in an electric vehicle. Electric cars run on batteries charged electrically even from solar panels. But hydrogen-powered cars produce their own electricity.

So, unlike a combustion engine, which produces carbon dioxide, the only end products of this hydrogen-powered reaction are electricity, water and heat. The only exhaust products are water vapour and warm air.
