Japanese shipping company Mitsui O.S.K. Lines (MOL) achieved a significant milestone by producing green hydrogen offshore with its demonstrator yacht, Winz Maru, and delivering it onshore to Tokyo. The vessel, equipped with an onboard plant, converted the hydrogen to the easily transportable liquid organic hydrogen carrier methylcyclohexane (MCH) for safer transportation. This operation, part of the Wind Hunter Project, is a step towards establishing a green hydrogen supply chain. Japan's focus on green hydrogen technologies underscores its commitment to transitioning away from fossil fuels. MOL's innovative approach includes utilizing wind power and underwater turbines to generate electricity and produce green hydrogen from seawater. The company aims to increase production, supply domestically produced green hydrogen, and provide electricity generated using hydrogen to facilities in Tokyo. Moreover, Japan's strategic emphasis on green hydrogen aligns with its goal of achieving carbon neutrality by 2050. The article highlights recent advancements in hydrogen production, such as the University of Adelaide's cost-effective seawater splitting method, indicating the growing potential of green hydrogen as a renewable energy source amid global efforts to reduce carbon emissions.
