Obayashi Corporation, in partnership with Halcyon Power and Fiji Gas, achieved success in a demonstration project to transport green hydrogen from New Zealand to Fiji. The project aimed to contribute to Japan's greenhouse gas emissions reduction target by utilizing geothermal-derived green hydrogen in Fiji through a hydrogen/diesel dual-fuel generator. Obayashi managed the project, facilitated safe marine transportation, and confirmed the feasibility of utilizing green hydrogen for electricity generation. Green hydrogen was shipped from Auckland to Lautoka Port in Fiji and used to power buildings through a dual-fuel generator. This successful initiative showcased the potential of international collaboration and marine transportation in promoting sustainable energy practices. The project not only demonstrated the technical feasibility of transporting green hydrogen but also emphasized the importance of utilizing renewable energy sources for a carbon-neutral society. By promoting the use of green hydrogen derived from renewable sources, the project aligns with the goal of reducing greenhouse gas emissions. Overall, the demonstration project exemplifies a step towards a more sustainable and environmentally friendly energy future.
