Hydrogen

Hydrogen is most abundant molecules in the universe and already used in our society as variety of industrial feedstocks for ammonia productions, refinery, metal productions and so on. As more hydrogen is being produced in net-carbon-emission-free methods, its field of use is being expanded to fuels: mobility, power or heat generation. One of the problems with the use as fuel is hydrogen’s low energy density in ambient temperature and pressure. One way to increase the low energy density is by using LH2 (liquid hydrogen) as energy carrier. The use of LH2 as an energy carrier had been very limited for rockets engine fuel. LH2 market is now growing with fueling stations for fuel cell vehicles; forklifts, passenger vehicles, buses, trucks, material handling vehicles, mining vehicles, or other commercial vehicles. For dispensing these vehicles, LH2 is stored in the ground storage and converted to gaseous hydrogen by pumping and vaporizing before dispensing into the vehicles. Because the utilization of the fuel stations is becoming higher, it gives rise to LH2 liquefaction from produced gaseous hydrogen, trailers loading and transportation and offloading at fueling stations. Further expansion of field of use of LH2 is being made for transportation of LH2 carrier, fuel for marine vessels, trains, airplanes.
