Ahydrogen station is a storage or filling station for hydrogen fuel.[1] The hydrogen is dispensed by weight.[2][3] There are two filling pressures in common use: H70 or 700 bar, and the older standard H35 or 350 bar.[4] As of 2021[update], around 550 filling stations were available worldwide.[4]
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.[5][6]
As of 2019,[update] 98% of hydrogen is produced by steam methane reforming, which emits carbon dioxide.[13] The bulk of hydrogen is also transported to fueling stations in trucks, so pollution is also emitted in its transportation.[5]
Volatility
Hydrogen fuel is hazardous because of its low ignition energy, high combustion energy, and because it easily leaks from tanks.[14] Explosions at hydrogen filling stations have been reported.[15]
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.[16]
There are far fewer Hydrogen filling stations than gasoline fuel stations, which in the US alone numbered 168,000 in 2004.[17] Replacing the US gasoline infrastructure with hydrogen fuel infrastructure is estimated to cost a half trillion U.S. dollars.[18] A hydrogen fueling station costs between $1 million and $4 million to build.[19] In comparison, battery electric vehicles can charge at home or at public chargers. As of 2023, there are more than 50,000 public charging stations in the United States, with more than 130,000 outlets.[20] 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 30,000 in the U.S.,[20] generally cost between $100,000 and $250,000,[21] although Tesla superchargers are estimated to cost approximately $43,000.[22]
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.[23]
Locations
Consulting firm Ludwig-Bölkow-Systemtechnik tracks global hydrogen filling stations and publishes a map.[24]
