HYDROGEN FUELING STATION

Analogous to traditional gas fueling stations hydrogen fueling station serves as a storage/ filling station for hydrogen though they have more complex architecture. Hydrogen filling stations consist of additional devices such as a compressor unit which is used to compress the gas to a required pressure, and devices for the delivery of the gas. Some stations even contain production facilities in-case-of on-site refueling station. Furthermore, the potential risk of possible ignition of hydrogen at the station or in the vehicle during refueling increments additional rise of risk, which must be well-evaluated. According to the mode of delivery, there are two types of stations: i) off-site hydrogen recharging station, and ii) on-site recharging station. In the case of an off-site refueling station, hydrogen is supplied via pipelines, tube trailers etc. whereas in the case of on-site refueling station hydrogen is produced by extracting natural gas, electrolysis etc. at the recharging station.

As of 2020, there are 178 publicly available hydrogen stations of which 114 are situated in Japan alone. Similarly, Europe has more than 180 stations and the US has seen 44 stations as of 2020.
