鉄鋼業の水素を核としたクリーンエネルギー供給基地としての可能性

抄録

Japanese Steel Industry has so far been recognized as a typical complex of large-scale producer of a fundamental material(steel) and large-scale consumer of energy. Howeber, for the coming materials recycle society and hydrogen energy society, Japanese Steel Industry has been recently reevaluated to play a key role mainly due to its specific large-scale high-temperature infrastructure along with its operating technologies. Its by-products are also notable, especially, COG(Coke Oven Gas: by-product gas from Coke Oven Batteries) seems to be promising as a clean energy source for its amount and high H₂ content. Present and future status of COG as a hydrogen outsourcing source was discussed along with an ongoing H₂ amplifying technology development program. And a future perspective on Japanese Steel Industry as a comprehensive clean energy outsourcing base was proposed.
