Hydrogen Safety

Abstract

This paper presents basic understanding needed for safely utilizing hydrogen as energy resources. There have occurred a number of disasters caused by accidents in systems using hydrogen. Each of those disasters has contributed to the progress of science and/or technology. The hazards of hydrogen are attributable to its characteristics, and reliable methods for protection against such hazards are indispensable for appropriately making use of hydrogen. The importance for establishing reliable technology on hydrogen utilization is not to neglect but to understand the hazards of hydrogen.
