Project to demonstrate a low-pressure hydrogen-supply chain using MH tanks. (Ministry of the Environment, Demonstrating a regional, low-carbon hydrogen supply chain, “Project to demonstrate a low-pressure hydrogen delivery system to promote hydrogen use in buildings and city infrastructure”)

Abstract

This project demonstrates a low-pressure hydrogen-supply chain consisting of hydrogen production using renewable energy generated at a wind power-plant owned by the city of Muroran, hydrogen delivery to a hydrogen utilization facility using hydrogen absorbing alloy tanks (MH tanks), where the low-pressure hydrogen is used.

The hydrogen delivery system with unused heat from a hot bath facility. In addition, a hydrogen utilization facility was also installed at a public facility without heat supply from the facility. We are conducting demonstrations with a focus on future actual operations and disaster countermeasures. Hydrogen is also expected to be used as energy during disasters.

This project demonstrates both hydrogen production using electricity generated from the wind-power plant and the hydrogen delivery system for facilities and buildings in city blocks. (1) Hydrogen is produced by water electrolysis using the power generated at the Shukuzu wind power-plant. (2) Hydrogen is delivered to the hot bath facility, “Yurara” and the public facility, “Kiran” using the on-board MH tanks on trucks, and then (3) transferred to stationary MH tanks located at the buildings. (4) Electric power and hot water generated by hydrogen from the stationary MH tanks using fuel cells at each building are supplied to “Yurara” and “Kiran” (electric power only).
