If liquid hydrogen usage is sufficiently high at the fueling station, there may be no need to vent any boiloff generated from the LH2 storage tank. Boil-off gas should be minimized through system design, but where needed, the boil-off hydrogen along with any other hydrogen released must be vented through a local vent stack which is constructed to safely vent the hydrogen in accordance with CGA G5.5 and NFPA 2. These standards anticipate the possible ignition of hydrogen in a vent stack and have provisions for that to happen safely. If economical, the boil-off gas can also be captured by using a gas compressor to store the gas for dispensing into vehicles.
