Mitsui O.S.K. Lines, Ltd. has announced that green H₂ produced from offshore wind using the demonstration yacht “Winz Maru” was supplied onshore in the central breakwater area of Tokyo in the “Wind Hunter Project,” a zero-emission project utilizing wind power and H₂ promoted by MOL. This marks the first time in the world that a ship has supplied green H₂, produced on its own while underway, for use onshore.

Between FY2021 and FY2023, MOL conducted a demonstration test in Omura Bay (Sasebo City) with the Winz Maru and successfully completed all phases of H₂ production, storage and usage of stored H₂ onboard. Since FY2023, in response to the adoption of the “Prior Projects” in the Tokyo Bay eSG Project, MOL has focused on supplying domestically produced green H₂ from the Winz Maru in Tokyo Bay to onshore facilities.

The Winz Maru makes it easy to handle and transport H₂, a difficult process for H₂ gas, by converting produced green H₂ to methylcyclohexane (MCH) onboard the vessel in Tokyo Bay. To ensure sufficient supply, MOL has modified the MCH tanks and added turbine generators to the vessel. In addition, safety measures have been taken in light of rougher sea conditions in Tokyo Bay, compared to Omura Bay.

MOL plans to continue its green H₂ production activities in Tokyo Bay, producing about 100 Nm³ of H₂ (the equivalent of about 200 liters of MCH) in FY2025, while at the same time supplying electricity to a trailer home and other facilities in the central breakwater area of Tokyo.

MOL is also working on studying a demonstration vessel and H₂ supply chains for Wind Hunter. Assuming that the H₂ value chain will be established domestically in the future, we aim to construct a demonstration vessel and commercialize the vessel as early as the 2030s. Additionally, a model ship of the Wind Hunter will be exhibited in the “Transportation and Mobility" zone of the "Future Society Showcase" pavilion at the 2025 World Exposition ("Expo 2025 Osaka, Kansai, Japan"), which will be held from Sunday, April 13th this year.

MOL is committed to promoting the creation of a green H₂ supply chain and a decarbonized society through the Wind Hunter.
