Hydrogen vehicle - Wikipedia

A working toy model car runs on solar power , using a regenerative fuel cell to store energy in the form of hydrogen and oxygen gas. It can then convert the fuel back into water to release the solar energy. A land-speed record for a hydrogen-powered vehicle of A record of As of [update] , there are 3 hydrogen cars publicly available in select markets: Hyundai Nexo succeeded it in Toyota launched its first production fuel cell vehicle FCV , the Mirai , in Japan at the end of and began sales in California, mainly the Los Angeles area , in Fuel-cell buses are being trialed by several manufacturers in different locations, for example, Ursus Lublin.

In northern Germany in the first fuel-cell powered Coradia iLint trains were placed into service; excess power is stored in lithium-ion batteries.

General Motors ' military division, GM Defense , focuses on hydrogen fuel cell vehicles. Since April , the U. ENV develops electric motorcycles powered by a hydrogen fuel cell, including the Crosscage and Biplane. Other manufacturers as Vectrix are working on hydrogen scooters. Autostudi S. A concept for a hydrogen-powered tractor has been proposed. Companies such as Boeing , Lange Aviation , and the German Aerospace Center pursue hydrogen as fuel for manned and unmanned airplanes.

In February Boeing tested a manned flight of a small aircraft powered by a hydrogen fuel cell. Unmanned hydrogen planes have also been tested. In July , Boeing unveiled its hydrogen-powered Phantom Eye UAV , powered by two Ford internal-combustion engines that have been converted to run on hydrogen.

In Britain, the Reaction Engines A2 has been proposed to use the thermodynamic properties of liquid hydrogen to achieve very high speed, long distance antipodal flight by burning it in a precooled jet engine.

A HICE forklift or HICE lift truck is a hydrogen fueled, internal combustion engine -powered industrial forklift truck used for lifting and transporting materials. It used a 2.

A fuel cell forklift also called a fuel cell lift truck is a fuel cell powered industrial forklift truck. In there were over 4, fuel cell forklifts used in material handling in the US. Most companies in Europe and the US do not use petroleum powered forklifts, as these vehicles work indoors where emissions must be controlled and instead use electric forklifts.

They can be used in refrigerated warehouses, as their performance is not degraded by lower temperatures. The fuel cell units are often designed as drop-in replacements. According to the Tsiolkovsky rocket equation , a rocket with higher exhaust velocity uses less propellant to accelerate. Also the energy density of hydrogen is greater than any other fuel.

This increases the rocket's structural mass which reduces its delta-v significantly.

Due to the constant hydrogen boil-off, the rocket must be fueled shortly before launch, which makes cryogenic engines unsuitable for ICBMs and other rocket applications with the need for short launch preparations.

Overall, the delta-v of a hydrogen stage is typically not much different from that of a dense fuelled stage, but the weight of a hydrogen stage is much less, which makes it particularly effective for upper stages, since they are carried by the lower stages.

For first stages, dense fuelled rockets in studies may show a small advantage, due to the smaller vehicle size and lower air drag. Nikola plans two versions of the hydrogen powered truck, long haul Nikola One and day cab Nikola Two. Hydrogen internal combustion engine cars are different from hydrogen fuel cell cars. The hydrogen internal combustion car is a slightly modified version of the traditional gasoline internal combustion engine car.

These hydrogen engines burn fuel in the same manner that gasoline engines do; the main difference is the exhaust product. Gasoline combustion results in carbon dioxide and water vapor , while the only exhaust product of hydrogen combustion is water vapor.

In Francois Isaac de Rivaz designed the first hydrogen-fueled internal combustion engine. The advantage of using an internal combustion engine, like Wankel and piston engines, is the lower cost of retooling for production. HICE forklift trucks have been demonstrated [59] based on converted diesel internal combustion engines with direct injection. The problems in early fuel-cell designs at low temperatures concerning range and cold start capabilities have been addressed so that they "cannot be seen as show-stoppers anymore".

The service life of fuel cells is comparable to that of other vehicles. Hydrogen does not exist in convenient reservoirs or deposits as do fossil fuels or helium [70] and is produced from feedstocks such as natural gas and biomass or electrolyzed from water. Integrated wind-to-hydrogen power to gas plants, using electrolysis of water , are exploring technologies to deliver costs low enough, and quantities great enough, to compete with traditional energy sources.

According to Ford Motor Company, hydrogen fuel-cell vehicles would generate only three-fifths the carbon dioxide as a comparable vehicle running on gasoline blended to 10 percent ethanol. The challenges facing the use of hydrogen in vehicles include chiefly its storage on board the vehicle.

While the well-to-wheel efficiency for hydrogen from the least efficient manner of producing it electrolysis is less than 25 percent, [7] [77] [78] [79] it still exceeds that of vehicles based on internal combustion engines. The molecular hydrogen needed as an onboard fuel for hydrogen vehicles can be obtained through many thermochemical methods utilizing natural gas , coal by a process known as coal gasification , liquefied petroleum gas , biomass biomass gasification , by a process called thermolysis , or as a microbial waste product called biohydrogen or Biological hydrogen production.

Environmental consequences of the production of hydrogen from fossil energy resources include the emission of greenhouse gasses , a consequence that would also result from the on-board reforming of methanol into hydrogen.

For example, Iceland is using geothermal power to produce hydrogen, [87] and Denmark is using wind. Compressed hydrogen in hydrogen tanks at bar 5, psi and bar 10, psi is used for hydrogen tank systems in vehicles, based on type IV carbon-composite technology. Hydrogen has a very low volumetric energy density at ambient conditions, equal to about one-third that of methane. Even when the fuel is stored as liquid hydrogen in a cryogenic tank or in a compressed hydrogen storage tank , the volumetric energy density megajoules per liter is small relative to that of gasoline.

Department of Energy , found a single-stage method for recharging ammonia borane, a hydrogen storage compound. Ammonia is easier to transport safely in tankers than pure hydrogen. The hydrogen infrastructure consists of hydrogen-equipped filling stations , which are supplied with hydrogen via compressed hydrogen tube trailers , liquid hydrogen tank trucks or dedicated onsite production, and some industrial hydrogen pipeline transport. The distribution of hydrogen fuel for vehicles throughout the U.

As of [update] , there were 40 publicly accessible hydrogen refueling stations in the US, most of which are in located in California compared with 19, electric charging stations. Hydrogen codes and standards , as well as codes and technical standards for hydrogen safety and the storage of hydrogen , have been identified as an institutional barrier to deploying hydrogen technologies and developing a hydrogen economy.

To enable the commercialization of hydrogen in consumer products, new codes and standards must be developed and adopted by federal, state and local governments. In , George W. Bush announced an initiative to promote hydrogen powered vehicles.

Under heavy criticism, the funding was partially restored.

Fuel cells could also be used in handling equipment such as forklifts as well as telecommunications infrastructure. Senator Byron L. Dorgan stated in In June , the U. Department of Energy gave 9 million dollars in grants to speed up technology development, 4. In Japan, hydrogen is mainly to be sourced from outside Japan.

Norway plans a series of hydrogen refueling stations along the main roads. Critics claim the time frame for overcoming the technical and economic challenges to implementing wide-scale use of hydrogen cars is likely to last for at least several decades, and hydrogen vehicles may never become broadly available. In the meantime, fuel cells are diverting resources from more immediate solutions. Critiques of hydrogen vehicles are presented in the documentary, Who Killed the Electric Car? According to former U.

Department of Energy official Joseph Romm , "A hydrogen car is one of the least efficient, most expensive ways to reduce greenhouse gases. Any way you look at it, hydrogen is a lousy way to move cars. The revised mandate allows manufacturers to comply with the rules by building more battery-electric cars instead of fuel-cell vehicles. On the other hand, if the hydrogen could be produced using renewable energy, "it would surely be easier simply to use this energy to charge the batteries of all-electric or plug-in hybrid vehicles.

A study at UC Davis , published in the Journal of Power Sources , similarly found that, over their lifetimes, hydrogen vehicles will emit more carbon than gasoline vehicles. Volkswagen's Rudolf Krebs said in that "no matter how excellent you make the cars themselves, the laws of physics hinder their overall efficiency.

The most efficient way to convert energy to mobility is electricity. You then must compress the hydrogen and store it under high pressure in tanks, which uses more energy. Krebs continued: Pure hydrogen can be industrially derived, but it takes energy. If that energy does not come from renewable sources, then fuel-cell cars are not as clean as they seem. Another challenge is the lack of infrastructure. Gas stations need to invest in the ability to refuel hydrogen tanks before FCEVs [fuel cell electric vehicles] become practical, and it's unlikely many will do that while there are so few customers on the road today.

Compounding the lack of infrastructure is the high cost of the technology.

Fuel cells are "still very, very expensive". In , Joseph Romm devoted three articles to updating his critiques of hydrogen vehicles. He stated that fuel cell vehicles still have not overcome the following issues: He concluded that renewable energy cannot economically be used to make hydrogen for an FCV fleet "either now or in the future. A analysis published in Green Car Reports concluded that the best hydrogen-fuel-cell vehicles consume "more than three times more electricity per mile than an electric vehicle Hydrogen vehicles compete with various proposed alternatives to the modern fossil fuel powered vehicle infrastructure.

Plug-in hybrid electric vehicles , or PHEVs, are hybrid vehicles that can be plugged into the electric grid and contain an electric motor and also an internal combustion engine. The PHEV concept augments standard hybrid electric vehicles with the ability to recharge their batteries from an external source, enabling increased use of the vehicle's electric motors while reducing their reliance on internal combustion engines.

This, however, is not the only energy loss in transferring power from grid to wheels. Natural gas has a higher energy density than hydrogen gas. NGVs using biogas are nearly carbon neutral. Worldwide, there were A Technology Review article stated, "Electric cars—and plug-in hybrid cars—have an enormous advantage over hydrogen fuel-cell vehicles in utilizing low-carbon electricity.

That is because of the inherent inefficiency of the entire hydrogen fueling process, from generating the hydrogen with that electricity to transporting this diffuse gas long distances, getting the hydrogen in the car, and then running it through a fuel cell—all for the purpose of converting the hydrogen back into electricity to drive the same exact electric motor you'll find in an electric car.

Some electric car designs offer limited driving range causing range anxiety. In John Swanton of the California Air Resources Board , who sees EVs and hydrogen vehicles as complementary technologies, stated that EVs have the jump on fuel-cell autos, which "are like electric vehicles were 10 years ago. EVs are for real consumers, no strings attached. With EVs you have a lot of infrastructure in place. Gas stations need to invest in the ability to refuel hydrogen tanks before FCEVs become practical, and it's unlikely many will do that while there are so few customers on the road today.

Fuel cells are "still very, very expensive", even compared to battery-powered EVs. From Wikipedia, the free encyclopedia. Further information: Fuel cell vehicle. Main article: PHB bicycle.
