HCNG dispenser
An HCNG dispenser is a type of fuel dispenser at a filling station that is used to pump hydrogen compressed natural gas (HCNG) into vehicles. == Principle == An HCNG dispenser is in general combined with a CNG dispenser for natural gas vehicles as both use the same feed stream from the compressed natural gas grid, in addition the hydrogen production method differs per station, some stations use on-site generation where other stations use on-site delivery of hydrogen to feed the HCNG dispensers.
