CHARACTERISTICS OF HEAT-HYDROGEN GAS ENERGY-CONVERSION AND HYDROGEN GAS TRANSPORTATION USING HYDROGEN ABSORBING ALLOY

Heat-hydrogen pressure conversion techniques and techniques for hydrog en gas transport over a long distance have been investigated to develo p elemental technologies required for constructing a high-efficiency s ystem to convert waste heat generated in industrial areas into hydroge n gas energy using hydrogen absorbing alloys. To efficiently convert h eat into hydrogen gas energy using hydrogen absorbing alloys, we studi ed the effect of the use of a plate fin type alloy fill vessel and hea t accelerators (copper, aluminium, and magnesium particles) mixed in t he alloy layer. We also studied the characteristics of the hydrogen ga s being transported through a 1-km piping unit.
