Hydrogen Storage System for the Hydrogen Powered Vehicles Key Technology for the Hydrogen Society

Abstract

Transport is consuming approximately one quarter of total energy consumption. Use of hydrogen to drive vehicles is very important for the realization of hydrogen society. However hydrogen characteristics make it quite difficult to store hydrogen on board, and a limited vehicle range makes a widespread use of the fuel cell vehicles difficult. This paper describes one effort to combine the classic metal hydride and the high pressure to improve the system storage density and summarizes the current efforts and a future potential of hydrogen storage technologies.
