Hydrogen Refueling Station
Overview
Hydrogen refueling stations gather the infrastructures needed to refill fuel-cell vehicles with hydrogen.
- They include hydrogen supply (e.g. onsite production), compression, storage, cooling and dispensing.
DESIGN OPTIONS
- Type of vehicles to refill: bikes, drones, forklifts, cars, buses, trucks, aircrafts etc.
- Refilling pressure: 350 and/or 700 bar
- Refilling speed: fast (a few minutes) or slow (up to hours)
- Hydrogen output capacity: max. # of fillings per day
- Dispensing capacities: simultaneous fillings, back-toback capacity

Multi-talents Enapter devices
How it works?
Enapter’s patented anion exchange membrane (AEM) electrolyser is a standardised, stackable and flexible system to produce on-site hydrogen. The modular design – paired with advanced software integration – allows set up in minutes and remote control and management. Stack this electrolyser to achieve the required hydrogen flowrate.

H2 Mobility Solutions
In 2021, Fuel Cell Systems developed a combined hydrogen refueling and heating system in Wales, as part of the MHEK project.
- The “Milford Haven: Energy Kingdom” project wants to demonstrate the practical application of hydrogen technology
- It features a refueling station integrating 2 Enapter electrolysers, for hydrogen-powered cars from the company Riversimple.
- A hydrogen-ready smart hybrid heating system has also been installed and is being tested in an operational Port building.

Hydrogen vehicles are quickly gaining ground around the globe
- On-site refueling for fuel cell drones, cars, planes or other vehicles is another use case for decentralized hydrogen production.
- Enapter is working with Hyperion Motors to supply the Hypercar with the clean fuel it needs for power.
- The HyFlyer project aims to decarbonise medium range passenger aircrafts using hydrogen.

- Narwhal 2” is a fuel cell drone that can carry up to 1kg of equipment
- It is mainly used for surveillance and can fly for 2 hours while transmitting video up to 30 km away.
- B-Shark also designed a mobile refueling station that integrates an Enapter electrolyser. Rather than buying large amounts of hydrogen and purchasing an additional compressor, generating hydrogen with our AEM electrolyser enabled the commercialisation of the drone.
