Title: Energy analysis and CO[sub 2] emission evaluation of a hydrogen energy system for the transportation system in Japan

Abstract

A concept of hydrogen energy system for the transportation system in Japan is proposed to replace all the fuel oil used by the transportation means with liquefied hydrogen (LH[sub 2]) in order to conserve petroleum and to reduce CO[sub 2] emission into the atmosphere. The hydrogen is produced by way of electrolysis with solar photovoltaic cells on a large number of ocean rafts in the South Pacific Ocean. All the elements of the hydrogen energy system for production, storage, and transportation are assumed to be built or fabricated with such conventional energies as coal, oil and electricity. The hydrogen energy system, at the present state of technologies, consumes the conventional energies more than the present petroleum energy system does. At the future developed state of technologies the hydrogen energy system can replace all the fuel oil consumed by the transportation means, 69 Mm[sup 3] a year, with LH[sub 2] of 24.9 Tg a year. The LH[sub 2] is produced on the rafts of which total area is about 6,000 km[sup 2] and is transported to Japan by 270 LH[sub 2] tankers of which capacity is 125,000 m[sup 3]. The hydrogen energy system can save 785 of the petroleum energy whichmore » the current transportation system would consume and can suppress 80[percent] of the CO[sub 2] emission which the petroleum consumption by the transportation means would release. If concrete is applied to the structure of the rafts, even the present technologies make the hydrogen energy system reduce 14[percent] of the CO[sub 2] emission.« less
