Characteristics of heat-hydrogen gas energy conversion and hydrogen gas transportation using hydrogen absorbing alloy

Heat-hydrogen pressure conversion techniques and techniques for hydrogen gas transport over a long distance have been investigated to develop elemental technologies required for constructing a high-efficiency system to convert waste heat generated in industrial areas into hydrogen gas energy using hydrogen absorbing alloys. To efficiently convert heat into hydrogen gas energy using hydrogen absorbing alloys, we studied the effect of the use of a plate fin type alloy fill vessel and heat accelerators (copper, aluminium, and magnesium particles) mixed in the alloy layer. We also studied the characteristics of the hydrogen gas being transported through a 1-km piping unit.
