A hydrogen station is a storage or filling station for hydrogen. The hydrogen is dispensed by weight. There are two filling pressures in common use. H70 or 700 bar, and the older standard H35 or 350 bar.
Hydrogen filling stations by region and countryEdit
A global map of hydrogen filling stations is available.
In 2019, there were 178 publicly available hydrogen fuel stations in operation.
In 2019, there were 114 publicly available hydrogen fuel stations in operation.
Japan built hydrogen filling stations under the JHFC project from 2002 to 2010 to test various technologies of hydrogen generation. By the end of 2012 there were 17 hydrogen stations. A task force led by Yuriko Koike, Japan's former environment minister, and supported by the country's Liberal Democratic Party, was set up in 2016 to oversee the process of building new hydrogen stations.
By the end of 2020, China had built 118 hydrogen refueling stations.
In 2019, there were 33 publicly available hydrogen fuel stations in operation. https://cnevpost.com/2021/07/01/china-has-built-118-hydrogen-refueling-stations/
As of June 2021,[update] there are 2 publicly available hydrogen fuel stations in operation, both in the Oslo area. Since the explosion at the hydrogen filling station in Sandvika in June 2019, the sale of hydrogen cars in Norway has halted.
In 2011 the first public hydrogen station opened in Swindon. In 2014 the London Hatton Cross station opened. In 2015, the London Hydrogen Network Expansion project opened the first supermarket-located hydrogen refuelling station at Sainsbury's in Hendon.
In 2018, Shell Canada launched an initiative to build hydrogen fueling stations starting with the first in Vancouver.
- Arizona: A prototype hydrogen fuelling station was built in compliance with all of the prevailing safety, environmental and building codes in Phoenix to demonstrate that such fuelling stations could be built in urban areas. As of January 2021,[update] no publicly accessible stations were in operation in Arizona.
- California: As of January 2021,[update] there were 43 stations. Hydrogen station development was encouraged and subsidized by the California Fuel Cell Partnership, and under Governor Arnold Schwarzenegger's California Hydrogen Highway program. In 2013, Governor Brown signed AB 8, a bill to fund up to 100 hydrogen stations.
- Massachusetts: The French company Air Liquide completed construction of a new hydrogen fuelling station in Mansfield, Massachusetts in October 2018, one of four stations they built as part of an expansion of the hydrogen fuelling infrastructure in the Northeastern U.S. The only other hydrogen fuelling station in Massachusetts is located at the Billerica, Massachusetts headquarters of fuel cell manufacturer Nuvera. As of January 2021,[update] no publicly accessible stations were in operation in Massachusetts.
Hydrogen recharging stations can be divided into off-site stations and on-site stations depending on how they supply hydrogen to vehicles (whether they produce their own hydrogen or not). Hydrogen recharging stations that have been built across Korea at the moment are mostly off-site (tube trailer-type) stations.
|Off-site hydrogen recharging station
(Hydrogen supplied from an external source)
|Hydrogen supplied from an external source
Hydrogen produced from a plant is supplied via pipelines, tube trailers, etc.
|On-site hydrogen recharging station
(Hydrogen produced directly at the station)
|Hydrogen produced by extracting (reforming) natural gas, electrolysis, etc. at the recharging station|
Types of recharging stationsEdit
A hydrogen highway is a chain of hydrogen-equipped filling stations and other infrastructure along a road or highway. Italy and Germany are collaborating to build a hydrogen highway between Mantua in northern Italy and Munich in southern Germany.
Home hydrogen fueling stationEdit
Solar powered water electrolysing hydrogen home stations are composed of solar cells, power converter, water purifier, electrolyzer, piping, hydrogen purifier, oxygen purifier, compressor, pressure vessels and a hydrogen outlet.
Daily recharging capacityEdit
Currently, the hydrogen recharging stations built by Hyundai Motor Group can recharge up to 70 Hyundai Nexo vehicles per day, assuming that the station is open for 14 hours daily. However, hydrogen recharging stations without high-pressure (900bar) storage tanks may require some additional downtime to repressurize the hydrogen in its recharging system if they refuel too many vehicles in a day.
As of 2019,[update] 98% of hydrogen is produced by steam methane reforming, which emits carbon dioxide. The bulk of hydrogen is also transported to fueling stations in trucks, so pollution is also emitted in its transportation.
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.
There are far fewer Hydrogen filling stations than gasoline fuel stations, which in the US alone numbered 168,000 in 2004 and generated revenues of US$536 billion in 2014. According to Joe Romm's book The Hype About Hydrogen (2004), replacing the gasoline infrastructure with hydrogen fuel infrastructure would cost a half trillion U.S. dollars. According to NREL, a hydrogen fueling station costs between $1 million and $4 million to build.
