Mitsubishi Heavy Industries, Ltd. (MHI) and NGK INSULATORS, LTD. (NGK) will jointly develop a hydrogen purification system that uses membrane separation to purify from hydrogen-nitrogen mixture gas after ammonia cracking. The companies expect the technology to contribute to the establishment of a hydrogen and ammonia supply chain enabling high-volume transport.

Optimal System for Purifying Hydrogen

Mainly, this joint project aims to build an optimal system for purifying hydrogen using membrane separation from the mixed gas of hydrogen and nitrogen after ammonia cracking. Specifically, MHI will contribute its significant global expertise delivering ammonia plants and other chemical plants. Also, it will share its technologies for handling ammonia and hydrogen. Meanwhile, NGK will contribute its deep knowledge of subnano ceramic membrane technology and unique film deposition technology developed in the fields of chemical processes and water purification. Primarily, they are the largest ceramic membranes, which are known for their exceptional separation accuracy and durability. Accordingly, MHI and NGK aim to drive the development forward, aiming to achieve early commercialization.

Nowadays, ammonia is garnering attention as a hydrogen carrier that enables safe transport and storage of hydrogen. Specifically, hydrogen does not emit CO₂ during combustion in large volumes over great distances. Plans to establish supply chains are underway worldwide, notably in Europe. Meanwhile, in Japan, a “Fuel Ammonia Supply Chain Establishment” project is in progress. This market is expected to grow in the years ahead.

Strategic Path to Achieving Carbon Neutrality

For its part, MHI Group is pursuing a growth strategy in energy transition, aiming for decarbonization on the energy supply side to support the company’s goal of achieving carbon neutrality by 2040. Through the development and commercialization of a membrane separation hydrogen purification system from ammonia cracking gas will contribute to building a hydrogen and ammonia supply chain, the company will strive for early establishment and execution of decarbonization technologies. This way, it can contribute to the realization of a sustainable carbon-neutral world.

Meanwhile, NGK Group has formulated a “Carbon Neutrality Strategic Roadmap” consisting of four strategies. Specifically, they aim to contribute to the realization of a carbon-neutral society and promote the development and provision of hydrogen and Carbon dioxide Capture, Utilization and Storage (CCUS) related technologies, and products.
