Hydrogen Energy is expected to be one of the keys to sustainable development. But this expectation comes from the idea focusing only on the particular phase of interest, such as production or use phase of hydrogen energy. The sustainability of the hydrogen energy will be clear by considering the Life-Cycle of the hydrogen energy system. In the present study, using the method of the Life-Cycle Assessment, the hydrogen energy system was analyzed considering the construction of infrastructures. The assessment aspects are Energy, CO_2, Cost and Land-Use. The hydrogen energy was also examined the adaptability to the vehicle fuel. The hydrogen energy which improves environmental impacts and costs in the acceptable range was selected. As a result, hydrogen energy for the vehicle fuel has to be produced by natural-gas reforming. And if the carbon tax is introduced, water electrolysis using the nuclear power is also possible.
