Obayashi Corporation, together with its group company Halcyon Power Limited and a local energy supplier Fiji Gas Pte Ltd., has realized success in a demonstration project to ship geothermal-derived green H₂ produced in New Zealand (NZ) to the Republic of Fiji and utilized it for fuel for a H₂/diesel dual-fuel generator (DF generator). The electricity generated by the generator was used to power buildings onsite.

The company conducted the Demonstration Project selected for the Ministry of the Environment Japan's "FY2022 Joint Crediting Mechanism (JCM) Financing Support Program: Pilot project for comprehensive support throughout the whole H₂ supply chain abroad", as an initiative to contribute to Japan's greenhouse gas (GHG) emissions reduction target.

As the representative participant of the demonstration project, the company managed the overall project, conducted field surveys, transported green H₂ by sea, supported the installation of the DF generator at Fiji Gas, and ultimately confirmed the feasibility of marine transportation and utilization of green H₂.

For Halcyon Power, which has been working on establishing a H₂ supply chain domestically since its opening of NZ's first MW-class H₂ production plant in December 2021, it was the first attempt to export green H₂ outside of NZ. To ensure safe marine transport, H2 gas filled in cylinders was shipped in compliance with the International Maritime Organization (IMO) regulations, including preparation of a Dangerous Goods Declaration.

Green H₂ was transported from Auckland Port in NZ to Lautoka Port in Fiji over a course of a week was utilized as fuel for a DF generator installed at Fiji Gas LPG Lautoka Terminal. The generator successfully supplied electricity by adjusting the H₂ flowrate to align with the facility's electricity demand.

The company will keep contributing to realizing a carbon-neutral society through further promoting the social implementation and deployment of green H₂ in collaboration with domestic and international stakeholders.
