Case Study on the Hydrogen Energy System in a Japanese typical city

Abstract

I will report the case study on the hydrogen energy system in a Japanese typical city. This city has 300 thousands populations and its area is 260 km². If the energy requirement that is equivalent to 30 thousands Tera Joule including electric generation, might be converted to the hydrogen energy system, the annual hydrogen supply shall reach to 180 thousands tons and about 15% of the carbon dioxide emission shall be reduced. One of main technical issues is the design of total system constitutions in consideration of the treatment of the boil off-gas evolved in handling of Ii quid hydrogen. For the realization of the hydrogen energy system in the near future, the development of hydrogen utilization will be essential that advantages of the hydrogen will be attained.
