Abstract:
Many countries are developing hydrogen energy systems for fuel cell vehicles to
embrace the low-carbon economy. Hydrogen refueling stations are one of the key
infrastructure components for the hydrogen-fueled economy. Skid-mounted hydrogen
refueling stations have smaller footprints and lower costs than traditional
hydrogen refueling stations, so they can be more easily commercialized. The
present work modeled hydrogen releases from a skid-mounted hydrogen refueling
station using the flame acceleration simulation (FLACS) software. The hydrogen
releases and dispersion were modeled for unintended leakages from the storage
tube bundles of a skid-mounted hydrogen refueling station for 5 mm and 10 mm
leak diameters in three different release directions. Hydrogen explosions were
modeled for flammable clouds ignited at different instants after the hydrogen
leakage. The results show that the hydrogen concentrations in the personnel
operating area are lower than in other areas, but the flammable clouds still
have an ignition risk. When the flammable cloud is ignited, both the people and
the equipment suffer serious thermal radiation damage with additional damage due
to the overpressures. When the hydrogen concentrations approach the
stoichiometric ratio, the explosion will cause serious injuries to personnel and
equipment inside the container. This work provides guidance for the structural
design of skid-mounted hydrogen refueling stations.
