A fuel cell vehicle (FCV) or fuel cell electrical vehicle (FCEV) is an electric vehicle that uses a fuel prison cell, sometimes in combination with a small battery or supercapacitor, to power its onboard electrical motor. Fuel cells in vehicles generate electricity generally using oxygen from the air and compressed hydrogen. Most fuel cell vehicles are classified as cipher-emissions vehicles that emit only water and estrus. As compared with internal combustion vehicles, hydrogen vehicles centralize pollutants at the site of the hydrogen production, where hydrogen is typically derived from reformed natural gas.[1] Transporting and storing hydrogen may too create pollutants.[2]

Fuel cells have been used in various kinds of vehicles including forklifts, especially in indoor applications where their clean emissions are important to air quality, and in infinite applications. The kickoff commercially produced hydrogen fuel cell automobile, the Hyundai ix35 FCEV, was introduced in 2013, the Toyota Mirai followed in 2015, and and so Honda entered the market place.[3] [iv] Fuel cells are being developed and tested in trucks, buses, boats, motorcycles and bicycles, among other kinds of vehicles.

Every bit of December 2020[update], 31,225 passenger FCEVs powered with hydrogen had been sold worldwide.[5] Every bit of 2021[update], there were only two models of fuel jail cell cars publicly available in select markets: the Toyota Mirai (2014–) and the Hyundai Nexo (2018–). The Honda Clarity was produced from 2016 to 2021, when it was discontinued.[6] As of 2020, there was express hydrogen infrastructure, with fewer than l hydrogen fueling stations for automobiles publicly available in the U.S.[seven] Critics doubt whether hydrogen will be efficient or toll-effective for automobiles, every bit compared with other zip emission technologies, and in 2019, The Motley Fool opined: "What's tough to dispute is that the hydrogen fuel cell dream is all but dead for the rider vehicle marketplace."[8]

Description and purpose of fuel cells in vehicles [edit]

All fuel cells are made upwards of three parts: an electrolyte, an anode and a cathode.[nine] In principle, a hydrogen fuel prison cell functions like a battery, producing electricity, which tin run an electric motor. Instead of requiring recharging, however, the fuel cell can be refilled with hydrogen.[ten] Different types of fuel cells include polymer electrolyte membrane (PEM) Fuel Cells, directly methanol fuel cells, phosphoric acid fuel cells, molten carbonate fuel cells, solid oxide fuel cells, reformed methanol fuel cell and Regenerative Fuel Cells.[11]

History [edit]

The concept of the fuel cell was start demonstrated by Humphry Davy in 1801, but the invention of the start working fuel cell is credited to William Grove, a chemist, lawyer, and physicist. Grove's experiments with what he called a "gas voltaic battery" proved in 1842 that an electric current could be produced past an electrochemical reaction betwixt hydrogen and oxygen over a platinum catalyst.[13] English language engineer Francis Thomas Salary expanded on Grove's work, creating and demonstrating various alkaline fuel cells from 1939 to 1959.[14]

The start modern fuel cell vehicle was a modified Allis-Chalmers farm tractor, fitted with a 15 kilowatt fuel cell, effectually 1959.[xv] The Common cold War Infinite Race drove further development of fuel cell technology. Project Gemini tested fuel cells to provide electric power during crewed infinite missions.[16] [17] Fuel prison cell development continued with the Apollo Program. The electric power systems in the Apollo capsules and lunar modules used alkali fuel cells.[16] In 1966, General Motors developed the first fuel prison cell road vehicle, the Chevrolet Electrovan.[18] It had a PEM fuel cell, a range of 120 miles and a top speed of 70 mph. At that place were only ii seats, equally the fuel cell stack and big tanks of hydrogen and oxygen took up the rear portion of the van. Only 1 was built, as the project was deemed price-prohibitive.[19]

General Electric and others continued working on PEM fuel cells in the 1970s.[xvi] Fuel cell stacks were all the same limited principally to space applications in the 1980s, including the Infinite Shuttle.[16] However, the closure of the Apollo Program sent many industry experts to private companies. By the 1990s, machine manufacturers were interested in fuel cell applications, and demonstration vehicles were readied. In 2001, the first 700 Bar (10000 PSI) hydrogen tanks were demonstrated, reducing the size of the fuel tanks that could exist used in vehicles and extending the range.[twenty]

Applications [edit]

At that place are fuel cell vehicles for all modes of send. The most prevalent fuel cell vehicles are cars, buses, forklifts and textile handling vehicles.[21]

Automobiles [edit]

The Honda FCX Clarity concept auto was introduced in 2008 for leasing past customers in Japan and Southern California and discontinued by 2015. From 2008 to 2014, Honda leased a total of 45 FCX units in the Usa.[22] Over twenty other FCEV prototypes and demonstration cars were released in that time period,[23] including the GM HydroGen4,[18] and Mercedes-Benz F-Cell.

The Hyundai ix35 FCEV Fuel Cell vehicle was available for lease from 2014 to 2018,[24] when 54 units were leased.[25] In 2018, Hyundai introduced the Nexo.[26]

Sales of the Toyota Mirai to government and corporate customers began in Japan in Dec 2014.[27] Pricing started at ¥six,700,000 (~Usa$57,400) before taxes and a authorities incentive of ¥2,000,000 (~The states$nineteen,600).[28] Erstwhile European Parliament President Pat Cox estimated that Toyota initially would lose about $100,000 on each Mirai sold.[29] As of Dec 2017[update], global sales totaled 5,300 Mirais. The top selling markets were the U.S. with ii,900 units, Japan with two,100 and Europe with 200.[30]

The Honda Clarity Fuel Jail cell was produced from 2016 to 2021.[31] [32] The 2017 Clarity had the highest combined and urban center fuel economy ratings amongst all hydrogen fuel cell cars rated by the EPA that year, with a combined city/highway rating of 67 miles per gallon gasoline equivalent (MPGe), and 68 MPGe in city driving.[33] In 2019, Katsushi Inoue, the president of Honda Europe, stated, "Our focus is on hybrid and electrical vehicles now. Possibly hydrogen fuel cell cars will come up, but that's a technology for the next era."[34]

By 2017, Daimler phased out its FCEV evolution, citing declining battery costs and increasing range of EVs,[35] and well-nigh of the automobile companies developing hydrogen cars had switched their focus to bombardment electric vehicles.[36] Past 2020, only three machine makers were nevertheless manufacturing, or had active manufacturing programs for hydrogen cars.[37]

Notes: One kg of hydrogen has roughly the same energy content as one U.S. gallon of gasoline. [38]

Fuel cells powered by an ethanol reformer [edit]

In June 2016, Nissan announced plans to develop fuel jail cell vehicles powered past ethanol rather than hydrogen. Nissan claims this technical approach would be cheaper, and that information technology would be easier to deploy the fueling infrastructure than a hydrogen infrastructure.[39] The vehicle would include a tank holding a blend of water and ethanol, which is fed into an onboard reformer that splits information technology into hydrogen and carbon dioxide. The hydrogen is then fed into a solid oxide fuel prison cell. According to Nissan, the liquid fuel could be an ethanol-water alloy at a 55:45 ratio.[39]

Buses [edit]

In 2011 there were over 100 fuel cell buses deployed around the world. Most of these buses were produced by UTC Power, Toyota, Ballard, Hydrogenics, and Proton Motor. UTC buses had accumulated over 970,000 km (600,000 mi) of driving.[40] Fuel cell buses have a thirty–141% higher fuel economic system than diesel buses and natural gas buses.[41] Fuel cell buses have been deployed in cities around the world,[42] although a Whistler, British Columbia project was discontinued in 2015.[43] In 2022, the urban center of Montpellier, France, cancelled a contract to procure 51 buses powered by hydrogen fuel cells, when it plant that "the cost of operation for hydrogen [buses] is six times the cost of electricity".[44]

Fuel cell bus projects have included:

  • 12 Fuel cell buses were deployed in the Oakland and San Francisco Bay area of California in 2007.[42]
  • Daimler AG, with thirty-six experimental buses powered by Ballard Power Systems fuel cells, completed a successful three-year trial, in eleven cities, in 2007.[45] [46]
  • A armada of Thor buses with UTC Power fuel cells was deployed in California, operated by SunLine Transit Bureau, in 2011.[47]
  • The commencement hydrogen fuel cell motorbus epitome in Brazil was deployed in São Paulo in 2009. The bus was manufactured in Caxias practice Sul, and the hydrogen fuel was to be produced in São Bernardo do Campo from water through electrolysis. The program, called Ônibus Brasileiro a Hidrogênio (Brazilian Hydrogen Autobus), included three buses.[48] [49]
  • Iii hydrogen fuel cell buses were introduced in Vienna, Austria, in 2022. Manufactured by Hyundai Motor Company and called Elec-city FCEV, the units were supplied equally part of the Austrian government's HyBus Projection. Further units are planned to be sent to Graz and Salzburg.[50]

Forklifts [edit]

A fuel cell forklift (also called a fuel prison cell lift truck or a fuel cell forklift) is a fuel cell-powered industrial forklift truck used to lift and transport materials. Almost fuel cells used in forklifts are powered past PEM fuel cells.[51]

In 2013, there were over 4,000 fuel cell forklifts used in textile handling in the US[52] from which but 500 received funding from DOE (2012).[53] [54] Fuel cell fleets are operated by a large number of companies, including Sysco Foods, FedEx Freight, GENCO (at Wegmans, Coca-Cola, Kimberly Clark, and Whole Foods), and H-Due east-B Grocers.[55] Europe demonstrated thirty fuel prison cell forklifts with Hylift and extended it with HyLIFT-EUROPE to 200 units,[56] with other projects in France[57] [58] and Austria.[59] Pike Inquiry stated in 2011 that fuel-cell-powered forklifts will be the largest driver of hydrogen fuel demand by 2020.[60]

PEM fuel-cell-powered forklifts provide significant benefits over petroleum powered forklifts as they produce no local emissions. Fuel-prison cell forklifts tin can work for a total eight-60 minutes shift on a single tank of hydrogen, tin can be refueled in iii minutes and take a lifetime of 8–10 years. Fuel cell-powered forklifts are often used in refrigerated warehouses as their performance is not degraded past lower temperatures.[61] In design the FC units are often made as drop-in replacements.[62] [63]

Motorcycles and bicycles [edit]

In 2005, the British house Intelligent Energy produced the first ever working hydrogen run motorcycle called the ENV (Emission Neutral Vehicle). The motorbike holds enough fuel to run for 4 hours, and to travel 160 km (100 mi) in an urban area, at a elevation speed of 80 km/h (fifty mph).[64] In 2004, Honda developed a fuel-prison cell motorbike which utilized the Honda FC Stack.[65] [66] In that location are other examples of bikes[67] and bicycles[68] with a hydrogen fuel cell engine. The Suzuki Burgman received "whole vehicle blazon" approval in the Eu.[69] The Taiwanese company APFCT conducts a live street test with 80 fuel cell scooters[70] for Taiwans Agency of Energy using the fueling arrangement from Italy's Acta SpA.[71]

Airplanes [edit]

The Boeing Fuel Cell Demonstrator powered by a hydrogen fuel cell

Boeing researchers and industry partners throughout Europe conducted experimental flight tests in February 2008 of a crewed airplane powered only past a fuel cell and lightweight batteries. The Fuel Cell Demonstrator Airplane, as it was called, used a Proton-Exchange Membrane (PEM) fuel cell/lithium-ion battery hybrid organization to ability an electrical motor, which was coupled to a conventional propeller.[72] In 2003, the world's commencement propeller driven airplane to be powered entirely past a fuel cell was flown. The fuel cell was a unique FlatStack stack blueprint which allowed the fuel prison cell to be integrated with the aerodynamic surfaces of the plane.[73]

There have been several fuel prison cell powered unmanned aerial vehicles (UAV). A Horizon fuel jail cell UAV fix the record distance flown by a small UAV in 2007.[74] The armed services is specially interested in this application because of the low noise, depression thermal signature and power to attain loftier altitude. In 2009, the Naval Inquiry Laboratory's (NRL'south) Ion Tiger utilized a hydrogen-powered fuel cell and flew for 23 hours and 17 minutes.[75] Boeing is completing tests on the Phantom Eye, a high-altitude, long endurance (HALE) to be used to conduct research and surveillance flying at 20,000 m (65,000 ft) for upwards to four days at a time.[76] Fuel cells are also beingness used to provide auxiliary power for aircraft, replacing fossil fuel generators that were previously used to start the engines and power on board electric needs.[76] Fuel cells tin help airplanes reduce CO2 and other pollutant emissions and dissonance.

Boats [edit]

The earth'south first Fuel Jail cell Boat HYDRA used an AFC system with 6.5 kW net output. For each liter of fuel consumed, the average outboard motor produces 140 times less[ citation needed ] the hydrocarbons produced by the average modern car. Fuel jail cell engines have college free energy efficiencies than combustion engines, and therefore offering ameliorate range and significantly reduced emissions.[77] Amsterdam introduced its first fuel cell powered boat in 2011 that ferries people effectually the city'southward canals.[78]

Submarines [edit]

The first submersible awarding of fuel cells is the German Type 212 submarine.[79] Each Blazon 212 contains nine PEM fuel cells, spread throughout the send, providing between 30 kW and l kW each of electrical ability.[lxxx] This allows the Type 212 to remain submerged longer and makes them more difficult to notice. Fuel cell powered submarines are too easier to design, manufacture, and maintain than nuclear-powered submarines.[81]

Trains [edit]

In March 2015, China Due south Rail Corporation (CSR) demonstrated the globe's first hydrogen fuel jail cell-powered tramcar at an assembly facility in Qingdao.[82] 83 miles of tracks for the new vehicle were built in seven Chinese cities. China had plans to spend 200 billion yuan ($32 billion) over the next five years to increase tram tracks to more 1,200 miles.[83]

In 2016, Alstom debuted the Coradia iLint, a regional train powered by hydrogen fuel cells. Information technology was designed to reach 140 kilometres per hour (87 mph) and travel 600–800 kilometres (370–500 mi) on a full tank of hydrogen.[84] The train entered service in Germany in 2018 and is expected to be tested in holland beginning in 2019.[85]

Swiss manufacturer Stadler Rail signed a contract in California to supply a hydrogen fuel cell train in the United states, the FLIRT H2 train, in 2024 as office of the Pointer rail projection.[86]

Trucks [edit]

Hyundai Xcient Fuel Cell in Winterthur, Switzerland

In 2020, Hyundai started to industry hydrogen powered 34-ton cargo trucks under the model name XCIENT, making an initial shipment of x of the vehicles to Switzerland. They are able to travel 400 kilometres (250 mi) on a total tank and take eight to twenty minutes to make full upwardly.[87]

In 2022, Full Transportation Services (TTSI), Toyota Logistics Services (TLS), UPS, and Southern Counties Express (SCE) are operating a 12-month "Shore-to-Store (S2S) project" running hydrogen fuel cell trucks on trips from Los Angeles area ports.[88] [89] The Kenworth T680 hydrogen prototype used in Los Angeles and Long Beach was unveiled in 2018 and has as well been tested in the Seattle area.[90]

Hydrogen infrastructure [edit]

Eberle and Rittmar von Helmolt stated in 2010 that challenges remain before fuel cell cars can become competitive with other technologies and cite the lack of an extensive hydrogen infrastructure in the U.S.:[91] As of July 2020[update], at that place were 43 publicly accessible hydrogen refueling stations in the US, 41 of which were located in California.[vii] In 2013, Governor Jerry Brownish signed AB 8, a bill to fund $xx million a year for 10 years to build upwards to 100 stations.[92] In 2014, the California Free energy Commission funded $46.6 million to build 28 stations.[93]

Japan got its starting time commercial hydrogen fueling station in 2014.[94] By March 2016, Nippon had 80 hydrogen fueling stations, and the Japanese government aims to double this number to 160 by 2020.[95] In May 2017, at that place were 91 hydrogen fueling stations in Nippon.[96] Germany had 18 public hydrogen fueling stations in July 2015. The German authorities hoped to increment this number to l by end of 2016,[97] simply simply thirty were open in June 2017.[98]

Codes and standards [edit]

Under United Nations global technical regulations for wheeled vehicles, specifically regarding hydrogen usage, at that place are international standards which define aspects of engineering science and overall integrity, performance, safety, part lifecycle, and various other categories. One notable area of these regulations is regarding the compressed hydrogen storage systems that typically reach the end of qualified service life at fifteen or fewer years in utilise.[99]

The states programs [edit]

In 2003, Us President George Bush proposed the Hydrogen Fuel Initiative (HFI). The HFI aimed to further develop hydrogen fuel cells and infrastructure technologies to advance the commercial introduction of fuel cell vehicles. By 2008, the U.S. had contributed 1 billion dollars to this project.[100] In 2009, Steven Chu, then the United states of america Secretary of Energy, asserted that hydrogen vehicles "will not be practical over the next ten to xx years".[101] [102] In 2012, however, Chu stated that he saw fuel jail cell cars as more than economically feasible as natural gas prices had fallen and hydrogen reforming technologies had improved.[103] [104] In June 2013, the California Energy Commission granted $eighteen.7M for hydrogen fueling stations.[105] In 2013, Governor Brown signed AB 8, a bill to fund $20 1000000 a yr for ten years for upwards to 100 stations.[92] In 2013, the US DOE announced upwards to $4 one thousand thousand planned for "continued development of advanced hydrogen storage systems".[106] On May 13, 2013, the Energy Department launched H2USA, which is focused on advancing hydrogen infrastructure in the US.[107]

Toll [edit]

By 2010, advancements in fuel prison cell engineering science had reduced the size, weight and cost of fuel cell electric vehicles.[108] In 2010, the U.South. Department of Free energy (DOE) estimated that the price of automobile fuel cells had fallen 80% since 2002 and that such fuel cells could potentially exist manufactured for $51/kW, assuming loftier-volume manufacturing cost savings.[109] Fuel cell electrical vehicles take been produced with "a driving range of more than 250 miles between refueling".[109] They can be refueled in less than v minutes.[110] Deployed fuel cell buses have a 40% higher fuel economy than diesel fuel buses.[108] EERE's Fuel Cell Technologies Programme claims that, as of 2011, fuel cells accomplished a 42 to 53% fuel cell electric vehicle efficiency at total power,[108] and a durability of over 75,000 miles with less than 10% voltage degradation, double that achieved in 2006.[109] In 2012, Lux Research, Inc. issued a report that ended that "Uppercase cost ... will limit adoption to a mere 5.9 GW" by 2030, providing "a nearly insurmountable bulwark to adoption, except in niche applications". Lux'southward analysis concluded that past 2030, PEM stationary fuel jail cell applications will reach $1 billion, while the vehicle market, including fuel jail cell forklifts, will reach a total of $2 billion.[111]

Environmental impact [edit]

The environmental impact of fuel cell vehicles depends on the primary energy with which the hydrogen was produced. Fuel cell vehicles are only environmentally benign when the hydrogen was produced with renewable free energy.[112] If this is the case fuel cell cars are cleaner and more efficient than fossil fuel cars. However, they are non as efficient every bit battery electrical vehicles which consume much less energy.[113] Usually a fuel cell car consumes two.four times more free energy than a battery electric car, because electrolysis and storage of hydrogen is much less efficient than using electricity to straight load a battery.[112]

Every bit of 2009, motor vehicles used most of the petroleum consumed in the U.South. and produced over threescore% of the carbon monoxide emissions and about 20% of greenhouse gas emissions in the United States, however product of hydrogen for hydro smashing used in gasoline production chief amongst its industrial uses was responsible for approximately 10% of armada wide greenhouse gas emissions.[114] In dissimilarity, a vehicle fueled with pure hydrogen emits few pollutants, producing mainly water and heat, although the production of the hydrogen would create pollutants unless the hydrogen used in the fuel jail cell were produced using only renewable energy.[115]

In a 2005 well-to-wheels analysis, the DOE estimated that fuel jail cell electric vehicles using hydrogen produced from natural gas would result in emissions of approximately 55% of the CO2 per mile of internal combustion engine vehicles and have approximately 25% less emissions than hybrid vehicles.[116] In 2006, Ulf Bossel stated that the large amount of energy required to isolate hydrogen from natural compounds (water, natural gas, biomass), bundle the low-cal gas by compression or liquefaction, transfer the energy carrier to the user, plus the free energy lost when it is converted to useful electricity with fuel cells, leaves effectually 25% for practical utilize."[117] Richard Gilbert, co-author of Transport Revolutions: Moving People and Freight without Oil (2010), comments similarly, that producing hydrogen gas ends up using some of the energy it creates. Then, energy is taken upwards by converting the hydrogen back into electricity inside fuel cells. "'This means that only a quarter of the initially available free energy reaches the electric motor' ... Such losses in conversion don't stack upwardly well against, for example, recharging an electrical vehicle (EV) similar the Nissan Leaf or Chevy Volt from a wall socket".[118] [119] A 2010 well-to-wheels analysis of hydrogen fuel jail cell vehicles written report from Argonne National Laboratory states that renewable H2 pathways offer much larger green house gas benefits.[120] This effect has recently been confirmed.[112] In 2010, a US DOE well-to-wheels publication assumed that the efficiency of the single step of compressing hydrogen to half dozen,250 psi (43.1 MPa) at the refueling station is 94%.[121] A 2016 study in the November issue of the journal Free energy by scientists at Stanford University and the Technical University of Munich concluded that, fifty-fifty assuming local hydrogen production, "investing in all-electric battery vehicles is a more economic option for reducing carbon dioxide emissions, primarily due to their lower cost and significantly college energy efficiency."[122]

Criticism of fuel cell cars [edit]

In 2008, professor Jeremy P. Meyers, in the Electrochemical Society journal Interface wrote that fuel cells "are not as efficient as batteries, due primarily to the inefficiency of the oxygen reduction reaction. ... [T]hey make the most sense for functioning disconnected from the grid, or when fuel can be provided continuously. For applications that require frequent and relatively rapid start-ups ... where zero emissions are a requirement, as in enclosed spaces such equally warehouses."[123] Also in 2008, Wired News reported that "experts say it will be 40 years or more before hydrogen has whatsoever meaningful impact on gasoline consumption or global warming, and we tin can't afford to wait that long. In the meantime, fuel cells are diverting resources from more immediate solutions."[124] In 2008, Robert Zubrin, the author of Energy Victory, said: "Hydrogen is 'just well-nigh the worst possible vehicle fuel'".[125] If hydrogen could be produced using renewable free energy, "information technology would surely be easier but to apply this energy to charge the batteries of all-electric or plug-in hybrid vehicles."[125] The Los Angeles Times wrote in 2009, "Any way you wait at it, hydrogen is a lousy style to movement cars."[126] The Washington Post asked in November 2009, "[W]hy would you lot want to store energy in the class of hydrogen and and then apply that hydrogen to produce electricity for a motor, when electrical energy is already waiting to be sucked out of sockets all over America and stored in auto batteries...?"[127]

The Motley Fool stated in 2013 that "at that place are withal cost-prohibitive obstacles [for hydrogen cars] relating to transportation, storage, and, most importantly, product."[128] Volkswagen'due south Rudolf Krebs said in 2013 that "no matter how excellent y'all make the cars themselves, the laws of physics hinder their overall efficiency. The most efficient mode to convert energy to mobility is electricity." He elaborated: "Hydrogen mobility merely makes sense if you utilise green energy", only ... you need to convert it first into hydrogen "with low efficiencies" where "you lose almost 40 percent of the initial energy". You then must compress the hydrogen and store information technology nether high force per unit area in tanks, which uses more free energy. "And then you take to convert the hydrogen back to electricity in a fuel jail cell with another efficiency loss". Krebs connected: "in the finish, from your original 100 percent of electrical energy, you lot cease up with 30 to 40 percent."[129]

In 2014, electrical automotive and energy futurist Julian Cox wrote that producing hydrogen from methane "is significantly more carbon intensive per unit of energy than coal. Mistaking fossil hydrogen from the hydraulic fracturing of shales for an environmentally sustainable energy pathway threatens to encourage energy policies that will dilute and potentially derail global efforts to caput-off climate change due to the risk of diverting investment and focus from vehicle technologies that are economically uniform with renewable energy."[130] In 2014, former Dept. of Energy official Joseph Romm concluded that renewable energy cannot economically be used to brand hydrogen for an FCV fleet "either now or in the time to come."[131] GreenTech Media'southward annotator reached similar conclusions in 2014.[132] In 2015, Clean Technica listed some of the disadvantages of hydrogen fuel cell vehicles.[133] [134]

A 2017 analysis published in Green Car Reports found that the best hydrogen fuel jail cell vehicles consume "more iii times more electricity per mile than an electrical vehicle ... generate more greenhouse-gas emissions than other powertrain technologies ... [and have] very high fuel costs. ... Considering all the obstacles and requirements for new infrastructure (estimated to cost every bit much as $400 billion), fuel-prison cell vehicles seem likely to be a niche applied science at best, with fiddling impact on U.Due south. oil consumption.[96] In 2017, Michael Barnard, writing in Forbes, listed the continuing disadvantages of hydrogen fuel prison cell cars and concluded that "past about 2008, it was very articulate that hydrogen was and would be inferior to battery technology as a storage of energy for vehicles. [B]y 2025 the last hold outs should likely exist retiring their fuel cell dreams."[135] A 2019 video by Real Technology noted that using hydrogen every bit a fuel for cars does not assist to reduce carbon emissions from transportation. The 95% of hydrogen even so produced from fossil fuels releases carbon dioxide, and producing hydrogen from water is an free energy-consuming process. Storing hydrogen requires more free energy either to cool information technology downwardly to the liquid state or to put it into tanks under high force per unit area, and delivering the hydrogen to fueling stations requires more than energy and may release more carbon. The hydrogen needed to move a FCV a kilometer costs approximately eight times as much as the electricity needed to move a BEV the same altitude.[136] Also in 2019, Katsushi Inoue, the president of Honda Europe, stated, "Our focus is on hybrid and electrical vehicles at present. Maybe hydrogen fuel cell cars will come up, but that's a applied science for the next era."[34]

Assessments since 2020 take concluded that hydrogen vehicles are still only 38% efficient, while battery EVs from 80% to 95% efficient.[137] [138] A 2021 assessment past CleanTechnica concluded that while hydrogen cars are far less efficient than electric cars, the vast majority of hydrogen existence produced is polluting grey hydrogen, and delivering hydrogen would crave edifice a vast and expensive new infrastructure, the remaining two "advantages of fuel cell vehicles – longer range and fast fueling times – are rapidly being eroded by improving battery and charging technology."[37] A 2022 report in Nature Electronics agreed.[139]

Innovation [edit]

Graph showing increase in fuel cell patent applications

Fuel cell patent fillings in the area of hydrogen fuel cells increased in the 1960s, partly due to NASAs space plan; another increase in the 80s was driven by enquiry for automobiles. This was followed past a surge in filings from 2000 to 2005 by inventors in Japan, Usa and South korea. Since so, China has dominated patent fillings in the field, with a smaller number in Japan, Germany, Republic of korea and the US.[140] Between 2016 and 2020, annual filings, particularly for transportation applications, increased by a further 23%.[141] [142]

Almost lxxx% of the patents in the area of fuel cells for transportation were filed by machine companies.[143] Academia is collaborating actively with the industry.[144] Although filings related to road vehicles such every bit cars and trucks dominate, inventions in other areas similar shipping, aviation, runway and other special vehicles is increasing.[145] Airbus, a major aircraft manufacturer, has increased its patenting activeness in the surface area since 2019.[146] The number of fuel cell patents for shipping applications is comparable in size to the one for aviation and similarly slow in growth.[144]

A World Intellectual Belongings System report argues that considering heavy-duty vehicles, such as construction vehicles, forklifts, and aerodrome tugs crave a higher payload, the loftier energy density of hydrogen can make fuel cells a more advantageous solution than battery applications.[146]

Notwithstanding, this 25% reduction is attributable to comparisons with the boilerplate American vehicle fleet of that time at only 23 miles per gallon and did not take into consideration like for similar emissions reduction alternatives that would be presented to vehicle consumers alongside a new FCV. For example mod gasoline hybrids of directly equivalent size and functioning. At 16.58Kg CO2e per Kilo of H2, the use of natural gas produced hydrogen is extremely carbon intensive, whereas the hybrid car uses less CO2 intensive gasoline at 11.3Kg CO2e per Kg (Argonne National Labs). DOE figures for gasoline well to wheel are lower at xi.13 Kg CO2e per Kg. As a result when comparing similar for like modern alternatives, a typical gasoline hybrid such as the Toyota Prius that achieves between 50 and 56 mpg depending on model variant produces between 24.7% and 32.2% less greenhouse gas emissions than a Toyota Mirai FCV and the Prius, its fuel and the feeling infrastructure to support information technology are considerably more than appealing to consumers and taxpayers primarily on account of price. A natural gas battery hybrid combustion engine motorcar emits about the same amount of CO2 (uses just as much natural gas) as a battery hybrid hydrogen fuel jail cell machine powered past natural gas derived hydrogen.
