MHI successfully produces hydrogen at ammonia cracking pilot plant
Mitsubishi Heavy Industries says that it has succeeded in producing 99% pure hydrogen by cracking ammonia using steam as the heating source. The production of hydrogen at pilot scale using the steam heating was conducted at the company’s pilot plant in the Nagasaki District Research & Innovation Centre, marking a world first. By contrast to technologies that use heat from burner combustion, MHI’s steam heating system operates at lower reaction temperatures, reducing operating costs. In addition, because a combustion furnace is not required, the system offers excellent features such as the potential for miniaturisation.
MHI aims to build on this achievement to promote the development of medium-scale, decentralised ammonia cracking systems near hydrogen demand sites. Based on the results of this pilot test, MHI, in collaboration with project partners Nippon Shokubai Co., Ltd. and Hokkaido Electric Power Co., Inc., will accelerate the development of this technology, which was selected by Japan’s New Energy and Industrial Technology Development Organization (NEDO) for its “Development of Technologies for Building a Competitive Hydrogen Supply Chain” project.
