Successfully creating a circular hydrogen supply chain
The Advanced Hydrogen Energy Chain Association for Technology Development (AHEAD),* in which NYK participates, has started the world’s first international demonstration operation to transport hydrogen. This project is subsidized by the New Energy and Industrial Technology Development Organization (NEDO) and will conduct a demonstration operation for the construction of an international hydrogen supply chain. Methylcyclohexane (MCH) produced in Brunei Darussalam has already been transported to Japan by ship, separated into hydrogen and toluene at a dehydrogenation plant located on the Kawasaki city waterfront, and the hydrogen has been supplied to a gas turbine at the Mizue power station owned by Toa Oil Co. Ltd.
At this time, the process of transporting back the toluene separated by dehydrogenation from Japan to Brunei Darussalam and binding the toluene again with hydrogen has started.** This would complete the hydrogen supply chain and would be the beginning of circular stable operation.
Outline of Demonstration Operation
Capacity of hydrogen transportation: 210 tons/year at full operation (equivalent to fully filling a 40,000 fuel cell vehicle)
Role of NYK in this project:
- Provide sea transportation and nautical data
- Cooperate with Yusen Logistics (subsidiary of NYK), which is in charge of forwarding business
- Collaborate with Ocean Network Express Pte. Ltd. (ONE), an affiliated company that is in charge of sea transportation using an ISO tank container
Milestones of Demonstration Project for a Hydrogen Energy Supply Chain
In the future, NYK will not only transport hydrogen but will also work to realize a hydrogen society, including the development of technology for utilizing hydrogen as a marine fuel. The company will also seek to accurately grasp business opportunities related to hydrogen, which is said to be the ultimate clean energy, and be involved in the entire supply chain.
** Chiyoda’s SPERA Hydrogen® Technology
Chiyoda’s SPERA Hydrogen® Technology utilizes the organic chemical hydride method. In the supply country, hydrogen chemically fixed to toluene is converted into Methylcyclohexane (MCH), a liquid at ambient temperature and pressure, through a hydrogenation reaction for storage and transport. In the‘demand country, hydrogen is extracted from the MCH through a dehydrogenation reaction and supplied as hydrogen gas.
“NYK is dedicated to achieving the SDGs (Sustainable Development Goals) through its business activities, and this demonstration operation to transport hydrogen will contribute to the below goals,” the company stated.
