题 目：Development of Hydrogen Supplying Chains for Future Hydrogen Society
摘 要：Hydrogen Energy has been continuously studied and developed on the level of National Projects in Japan since 1974. Private enterprises have been making every effort to make Hydrogen Energy Systems practically feasible. Two types of hydrogen supplying chains are thus under practical demonstration on large scales. Chiyoda Corporation carries methyl cyclohexane (to release hydrogen on chemical change to toluene) from Brunei, and Kawasaki Heavy Industries transports liquid hydrogen from Australia. A third hydrogen carrier, ammonia, has also been widely investigated under the auspices of the Government. Hydrogen storage alloys have also been widely studied, and practical use for stationary hydrogen storage has begun. If the cost of liquefaction goes lower and boil-off during storage is inhibited, liquid hydrogen will play important roles for hydrogen supply. Magnetic refrigeration using the magneto-caloric effect has potential to realize liquefaction efficiency higher than 50% to significantly reduce the cost. National Institute for Materials Science, NIMS, started Innovative Hydrogen Liquefaction Project in November, 2018. A proposed refrigeration cycle consisting of precooling cycle and magnetic active regenerator cycle would attain the efficiency goal, 50%, at a liquefaction velocity of 100 kg H2 / day. That efficiency is twice as high as the ordinary value by conventional gas refrigeration.
