In both cases, an extreme amount of energy is released with no toxic byproducts, which is what makes hydrogen fuel cells such a great power source for electric vehicles. The hydrogen itself can be produced by running this process in reverse, which is called electrolysis. Running an electrical current through water separates the H2O into hydrogen and oxygen. More commonly, however, hydrogen is produced at scale from natural gas in a process called steam-methane reforming , in which high-temperature and high-pressure steam is combined with natural gas to create hydrogen.
This dance of mechanics and chemistry is similar to the hydrogen-oxygen reaction that powers rocket engines. The state of California mandates that at least 33 percent of the hydrogen that goes into vehicles has to come from renewable sources, with the hope of eventually marching toward percent renewable energy.
That brings fuel-cell vehicles in line with battery electrics running off grid power. As battery electric cars come to the fore, the automotive industry is grappling with their two major downsides for drivers.
Fuel-cell vehicles don't have those problems. You can fill up quickly, the same way you would with gas or diesel. And once it has a full tank, a fuel-cell vehicle can travel just as far as a gas vehicle. The Toyota Mirai has the shortest range of any commercial fuel-cell sedan currently on the market and it goes miles on a full tank.
There is no barrier there. Compare that to the 2 kilowatts—a thousand times less power—that's available at a standard wall outlet. Battery vehicles are famous for their incredibly high performance—Tesla set a 0 to 60 record with one in But according to Stephen Ellis, fuel cell vehicle manager at American Honda, fuel cell cars can hold their own.
You can choose whatever kind of electric drive motor you want and apply it. However, all those benefits currently come at a high price. The cost of both the vehicle and the fuel should go down over time, but for now, the advantages of fuel cells will come with a hefty price tag. The industry is opening approximately one new fueling station a month, and is on track to meet its goal of stations in California by Bandolier Pins Bandolier Pins and Terminals made from open tooling, in a wide variety of sizes.

The First Hydrogen Fuel Cell Vehicle was Created in Clean energy technology has evolved by leaps and bounds since General Motors first introduced their Hydrogen Fuel Cell Electrovan Electrification of Transportation The Electrovan from General Motors is generally considered to be the first use of a hydrogen fuel cell to power a vehicle.
Figure 1 — Electric Vehicles are Growing in Popularity These new-generation hydrogen fuel cells are accelerating the use of clean energy in transportation. Bipolar Plates — At the Heart of the Energy Generation Process One of the most critical elements in PEMFCs are the Fuel Cell Bipolar Plates which distribute hydrogen and air, conduct electrical current from cell to cell, and remove heat from the active area, while avoiding leakage of gases or coolant.

But the company deemed it too expensive to continue. Plans were floated for a consumer trial in Leicester, but the project failed to secure funding and political approval. I ask why they never gave up on the idea. Spowers is nervous about what Brexit means for the company. But that is expected to change rapidly: in , the UK and France announced their intention to ban the sale of new petrol and diesel cars by Germany and China are expected to follow suit.
All Volvos will be electric or hybrid from Every major manufacturer is investing heavily in the development of electric cars such as the Tesla Model 3 and Nissan Leaf , which run on lithium-ion batteries. For a long time, the industry has explored another alternative to the combustion engine: hydrogen fuel cells.
To put it simply, fuel cells work by electrochemically combining hydrogen, stored in a pressurised tank, with air to generate an electric current; the only emission is water vapour. However, development of fuel cell technology has been slow. They are expensive to produce platinum is a key component , as is hydrogen. The gas is flammable and difficult to store. A longstanding defence made by hydrogen advocates is that it is more practical. Charging one battery car is very easy; filling one hydrogen car is impossible.
But as you scale, that situation completely reverses. Which is fine in places such as California, where home solar panels are practical year round, but less so in countries where the grid runs on dirty coal and natural gas. Add in the emissions of making the battery and, according to some academic studies , an electric car actually emits more CO 2 over its lifespan than an efficient petrol vehicle.
Solar and wind power are intermittent, which is why governments are piling money into grid storage technologies. To date, that has been considered too expensive. But so, too, will be the process of upgrading the electricity grid to deal with electric cars. Whereas if you design a car around the characteristics of hydrogen, you can essentially work around those barriers and they all disappear. H ugo Spowers had a privileged upbringing. Spowers credits his environmentalism to weekends working in the gardens.
