Summary

Air Liquide Japan has studied the hydrogen liquefaction process, focusing on the supply of liquid hydrogen to the stations for fuel-cell vehicles. A survey of state-of-the-art hydrogen liquefaction technology has led to determination of the best process: Proven technology reveals the feasibility of utilizing a cold source of LNG to reduce the power of hydrogen liquefaction. A feasibility study was further detailed through the cooperation of IHI, in which the cryogenic reciprocating compressor applied to HP-stages of hydrogen recycle compression at the production capacity of 3t/d was reviewed. It was found that this process gives a cost-effective solution in terms of the power of liquefaction and investment required. The cost for liquid hydrogen production was also estimated and evaluated. This is a promising process that could lead to further advantages in large capacity production.
