In Japan, Mitsubishi Heavy Industries, Ltd. (MHI) said 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 Center, marking a world first.
In contrast to conventional technologies that utilize 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 miniaturization, the company said.
“MHI, with the aim of building a hydrogen supply chain using ammonia as a hydrogen carrier, will build on this achievement to promote the development of medium-scale, decentralized 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,” the firm said.
