What is Hydrogen Refuelling Station
A hydrogen station is a storage or filling station for hydrogen fuel. 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. As of 2021, around 550 filling stations were available worldwide.

What are Advantages of Hydrogen Refuelling Station
Environmental Friendliness
Hydrogen, as a clean energy source, produces only water vapor upon combustion, eliminating the generation of pollutants. The construction of hydrogenation stations contributes to a reduction in air pollution and greenhouse gas emissions, promoting environmental protection.
High Energy Efficiency
Hydrogen fuel cell vehicles exhibit superior energy efficiency compared to traditional fuel vehicles. This results in reduced energy consumption and lower greenhouse gas emissions, contributing to sustainable and efficient transportation.
Convenience
Hydrogen refueling stations offer a convenient energy supply method for hydrogen fuel cell vehicles, akin to traditional gas stations. This allows for quick hydrogen injection, enhancing vehicle battery life and promoting the widespread adoption of hydrogen-powered vehicles.
Types of Hydrogen Refuelling Station
Gaseous Hydrogen Stations
Gaseous hydrogen stations store hydrogen gas under high pressure, typically at 350 to 700 bar (5,000 to 10,000 psi). These stations compress the hydrogen, which is then stored in high-pressure tanks before being dispensed to vehicles. Gaseous hydrogen stations are the most common type of hydrogen refueling station.
Liquid Hydrogen Stations
Liquid hydrogen stations store hydrogen in its liquid state at extremely low temperatures (-253°C or -423°F). These stations require more complex equipment and insulation to maintain the hydrogen at such low temperatures, but they offer advantages in terms of storage capacity and refueling speed.
The way a hydrogen station works is very similar to that of a conventional gasoline or diesel service station.
It has a storage place, a compressor, and a pump from which the hydrogen is supplied to vehicles. The renewable hydrogen is generated by using an electrolyzer or through the reforming of natural gas. The production can be carried out at the facility itself where the refueling station is located, which is known as a hydrogen station, or in a different location, which is known as hydroline station. In the case of hydroline stations, the hydrogen can be transported, either through a gas pipeline (called hydrogen pipeline) or by hydrogen bottles by road .
The hydrogen is pumped into the vehicle using a dispenser very similar to the one that is usually found in gas stations, but with some differences adapted to the physical characteristics of hydrogen, which is an extremely volatile gas that's supplied at high pressure. This way, you only have to bring the car close to the pump and hook up the dispenser to refill hydrogen quickly, cleanly, and safely since it's a process that usually takes less than five minutes.
The Key Components of a Hydrogen Refuelling Station
Hydrogen Inlet
Refuelling stations are configured for optimum performance based on the hydrogen inlet pressure. The hydrogen can be produced on site most commonly via electrolysis, delivered to site and fuelled directly from a tube trailer or via on-site storage.
Compression
The hydrogen is then compressed to increase the pressure, and reduce the volume, to enable a greater amount of hydrogen to be stored in the system and an efficient flow of gas for dispensing.
Heat Exchanger (Process Gas Chilling)
The compressed hydrogen is then passed through a heat exchanger to remove the excess heat from the gas that was generated during the compression process. Specially designed hydrogen-resistant valves and fittings are used to control the highly pressurised hydrogen. These components utilise specific materials that are resistant to hydrogen embrittlement to prevent any cracking.
Hydraulic Power Unit and Controls
The process is powered, monitored and controlled via the electronic control panel in the non-hazardous zone.
Dispensing Chiller System
The hydrogen is then cooled to subzero temperatures for fast and efficient filling to ensure the hydrogen can be dispensed safely and to comply with filling protocols i.e. J2601.
TVent Stacks
A safety feature to vent any escaped hydrogen safely. Hydrogen is lighter than air so dissipates quickly and safely, should an incident occur.
Storage
The high-pressure gas is then stored in the system until required for dispensing at the point of use. The storage is controlled by specially designed valves, fittings and electrical controls designed to regulate pressure and interact with the dispenser and vehicle as needed.
Dispenser
Designed to emulate traditional fuelling methods, the hydrogen is dispensed via a nozzle controlled by a smart valve which regulates the flow rate of the gas to fill the vehicle to the required pressure in accordance with the fuelling protocol.
