Different concepts for refuelling infrastructure exist that are suitable for different levels of hydrogen demand, from refuelling a single car to large refilling stations able to refuel multiple cars and buses on a daily basis. All hydrogen refuelling stations include the following basic components:
- Hydrogen production and supply
Hydrogen can be generated on-site
- by electrolysis of water
- by small scale reformation of natural gas
Hydrogen can be produced centrally and delivered to the site
- in liquefied form
- as gaseous hydrogen
- by tube trailer or via a pipeline
- produced via reforming of Natural Gas
- supplied as byproduct from industrial processes
- delivered as a liquid
- delivered as a compressed gas
- Cascade storage fill system
- Booster compressor fill system
