Marubeni Corporation

Marubeni Corporation (hereinafter, “Marubeni”) has completed a demonstration project (hereinafter, the “Project”) in South Australia (hereinafter, “SA”), involving the production of low-cost green hydrogen, the transportation of hydrogen to Indonesia using metal hydride^*1 tanks, and the utilization of hydrogen through fuel cells.

Green hydrogen production and energy storage facility in SA

About the Project
The Project was selected for the Ministry of Environment, Japan (MOEJ)’s “Pilot Project for Comprehensive Support throughout the Whole Hydrogen Supply Chain Abroad”^*2 and commenced in January 2022.

Leveraging an energy management system (EMS)^*3 provided by its subsidiary SmartestEnergy Australia, together with storage batteries, Marubeni produced low-cost, stable green hydrogen in SA using surplus renewable power. The green hydrogen was stored in metal hydride tanks and transported to Indonesia, where it was used to deliver power supply over an extended period at an industrial park in the suburbs of Jakarta via fuel cells. Through these activities, the Project demonstrated both the effectiveness of metal hydrides as a hydrogen transportation method and the feasibility of building a supply chain from production through to end-use.

Initiatives Following Completion of the Project
Marubeni will continue its efforts to utilize the hydrogen produced, including within Australia. To date, green hydrogen has been supplied to a natural gas power plant adjacent to the production facility in SA, enabling Australia’s first hydrogen co-firing trial from September 2025. Marubeni has entered into a hydrogen sales agreement with the plant owner, Iberdrola Australia, and will continue to supply low-cost hydrogen produced from surplus renewable power as a co-firing fuel for gas turbines. In addition, through the operation of the battery system introduced for hydrogen production, Marubeni also aims to provide grid-balancing functions.
Going forward, Marubeni aims to help realize a sustainable society by building and promoting projects that contribute to decarbonization, such as the supply and utilization of clean energy.

*1 Technology used to safely store and transport hydrogen (hydrogen is absorbed through cooling and pressurizing and is discharged through heating and decompression)
*2 Financing program for pilot projects which promote the production of green hydrogen in collaboration with a country where renewable energy is abundant and then transport that hydrogen for use in island nations or other similar countries. The purpose is to achieve Japan’s GHG emissions reduction targets through the JCM (Joint Credit Mechanism) initiative by promoting the production and utilization of green hydrogen in anticipation of future ripple effects.
*3 Technology used to optimize the entire energy system based on weather, power market price, and other information.
