A hydrogen infrastructure is the infrastructure of points of hydrogen production, truck and pipeline transport, and hydrogen stations for the distribution and sale of hydrogen fuel, and thus a crucial prerequisite before a successful commercialization of fuel cell technology.
Hydrogen stations which are not situated near a hydrogen pipeline get supply via compressed hydrogen tube trailers, liquid hydrogen trailers, liquid hydrogen tank trucks or dedicated onsite production. Pipelines are the cheapest way to move hydrogen over long distances but must be designed to withstand the leakage and steel embrittlement caused by the hydrogen molecule. Hydrogen gas piping is routine in large oil-refineries, because hydrogen is used to hydrocrack fuels from crude oil. The IEA recommends existing industrial ports be used for production and natural gas pipelines for transport, international co-operation and shipping.
South Korea and Japan, which as of 2019 lacked international electrical interconnectors, were investing in the hydrogen economy. In March 2020, the Fukushima Hydrogen Energy Research Field was opened in Japan, claiming to be the world's largest hydrogen production facility. Much of the site is occupied by a solar array; power from the grid is also used for electrolysis of water to produce hydrogen fuel.

Hydrogen highways and stations A hydrogen highway is a chain of hydrogen-equipped filling stations and other infrastructure along a road or highway which allow hydrogen vehicles to travel.
Hydrogen stations that are not situated near a hydrogen pipeline get deliveries of hydrogen tanks via compressed hydrogen tube trailers, liquid hydrogen trailers, liquid hydrogen tank trucks or dedicated onsite production. Governments have supported some initiatives to expand hydrogen fuel infrastructure in the US state of California, in some member states of the European Union, Japan and elsewhere.
Hydrogen pipeline transport Hydrogen pipeline transport may be used to connect the point of hydrogen production or delivery of hydrogen with the point of demand.DOE Hydrogen Pipeline Working Group Workshop According to a 2024 research report, the United States had 1,600 miles (2,570 kilometers) of hydrogen pipelines, and the global total stood at 2,800 miles (4,500 kilometers). The World Economic Forum, in December 2023, however, estimated that Europe had approximately 1,600 kilometers of hydrogen pipelines.
Hydrogen embrittlement (a reduction in the ductility of a metal due to absorbed hydrogen) occurs primarily with 'diffusible' hydrogen, i.e. atoms or ions. Hydrogen gas, however, is molecular (H2), and there is a significant energy barrier to splitting it into atoms.
Hydrogen production plants 98% of hydrogen production uses the steam reforming method. Methods such as electrolysis of water are also used. The world's largest facility for producing electrolytic hydrogen fuel is claimed to be the Fukushima Hydrogen Energy Research Field (FH2R), a 10MW-class hydrogen production unit, inaugurated on 7 March 2020, in Namie, Fukushima Prefecture. The site occupies 180,000 square meters of land, much of which is occupied by a solar array; but power from the grid is also used to conduct electrolysis of water to produce hydrogen fuel.
Hydrogen pipeline transport Hydrogen may be transported through pipes.

Economics
Hydrogen pipeline transport is sometimes used to transport hydrogen from the point of production or delivery to the point of demand. Although hydrogen pipeline transport is technologically mature,2005 DOE Hydrogen Pipeline Working Group Workshop most hydrogen is produced in the place of demand, with an industrial production facility every Every 50 to 100 miles
Piping For process metal piping at pressures up to , high-purity stainless steel piping with a maximum hardness of 80 HRB is preferred.Idaho national Engineering Laboratory Recommendations for Piping for Gaseous Hydrogen Accessed 2010-10-13 This is because higher hardnesses are associated with lower fracture toughness so stronger, higher hardness steel is less safe.
Composite pipes are assessed like: carbon fiber structure with fiberglass overlay . perfluoroalkoxy (PFA, MFA). polytetrafluoroethylene (PTFE) fluorinated ethylene propylene (FEP) . carbon-fiber-reinforced polymers (FRP)
Fiber-Reinforced Polymer pipelines (or FRP pipeline) and reinforced thermoplastic pipes are researched.
Carrying hydrogen in steel pipelines (grades: API5L-X42 and X52; up to 1,000psi/7,000kPa, constant pressure/low pressure cycling) does not lead to hydrogen embrittlement. Hydrogen is typically stored in steel cylinders without problems.

Hydrogen highway A hydrogen highway is a chain of hydrogen-equipped public filling stations, along a road or highway, that allows hydrogen powered cars to travel.Al-Ahmed, Amir, Safdar Hossain, Bello Mukhtar et al. "Hydrogen highway: An overview", IEEE.org, December 2010 William Clay Ford Jr. has stated that infrastructure is one of three factors (also including costs and manufacturability in high volumes) that hold back the marketability of fuel cell cars.
Supply issues, cost and pollution Hydrogen fueling stations generally receive deliveries of hydrogen by tanker truck from hydrogen suppliers. An interruption at a hydrogen supply facility can shut down multiple hydrogen fueling stations.Woodrow, Melanie. "Bay Area experiences hydrogen shortage after explosion", ABC news, June 3, 2019 A hydrogen fueling station costs between $1 million and $4 million to build.
As of 2019, 98% of hydrogen is produced by steam methane reforming, which emits carbon dioxide."Realising the hydrogen economy" , Power Technology, October 11, 2019 The bulk of hydrogen is also transported in trucks, so pollution is emitted in its transportation."Transportable Hydrogen Dispensing" , Protium.aero, May 2, 2016
Hydrogen station
A hydrogen station is a storage or filling station for hydrogen fuel. The hydrogen is dispensed by weight. Two filling pressures are in common use: H70 or 700 bar, and the older standard H35 or 350 bar. , around 550 filling stations were available worldwide. According to H2stations.org by Ludwig-Bölkow-Systemtechnik (LBST), as of the end of 2023, there were 921 hydrogen refueling stations globally, although this number clearly conflicts with those published by AFDC. The distribution of these stations is highly uneven, with a concentration in East Asia, particularly in China, Japan and South Korea; Central Europe and California in the United States. Other regions have very few, if any, hydrogen refuelling stations.
Delivery methods Hydrogen fueling stations can be divided into off-site stations, where hydrogen is delivered by truck or pipeline, and on-site stations that produce and compress hydrogen for the vehicles."Transportable Hydrogen Dispensing" , Protium.aero, May 2, 2016

Disadvantages Volatility Hydrogen fuel is hazardous because of its low ignition energy, high combustion energy, and because it easily leaks from tanks. Explosions at hydrogen filling stations have been reported.
Supply Hydrogen fuelling stations generally receive deliveries by truck from hydrogen suppliers. An interruption at a hydrogen supply facility can shut down multiple hydrogen fuelling stations due to an interruption of the supply of hydrogen.Woodrow, Melanie.

Costs
There are far fewer Hydrogen filling stations than gasoline fuel stations, which in the US alone numbered 168,000 in 2004. Replacing the US gasoline infrastructure with hydrogen fuel infrastructure is estimated to cost a half trillion U.S. dollars. A hydrogen fueling station costs between $1 million and $4 million to build. In comparison, battery electric vehicles can charge at home or at public chargers. As of 2025, there are more than 70,000 public charging stations in the United States, with more than 200,000 chargers. A public Level 2 charger, which comprise the majority of public chargers in the US, costs about $2,000, and DC fast chargers, of which there are more than 55,000 in the U.S., generally cost between $30,000 and $150,000 for equipment and installation;Ruedig, Allison. "Guide to Commercial EV Charging Station Cost & Installation", Greenlancer, July 3, 2025
Freezing of the nozzle During refueling, the flow of cold hydrogen can cause frost to form on the dispenser nozzle, sometimes leading to the nozzle becoming frozen to the vehicle being refueled.
