Japan has embarked on an innovative experiment that could revolutionize the maritime industry. A consortium of Japanese companies is testing the use of biomethane—derived from cow dung—as a clean and sustainable fuel source for ships. If successful, this project could set a new standard for clean energy and significantly reduce carbon emissions.
The feasibility study is being led by Mitsui OSK Lines (MOL), one of Japan’s largest shipping companies, in collaboration with Takanashi Milk Products, a leading dairy firm. The initiative also includes contributions from Hamanaka Town, JA Hamanaka, Hokkaido Gas Co., and MOL’s subsidiary, MOL Sunflower.
These six organizations are pooling their expertise to explore the viability of using biomethane produced in Hamanaka Town as a fuel for both factories and vessels. The project’s potential impact extends far beyond Japan, offering a scalable model for other countries aiming to reduce their carbon footprints.
Biomethane is a refined form of biogas produced from organic waste, including manure from dairy farms. Unlike traditional fossil fuels, biomethane is renewable and can be integrated into existing infrastructure, making it an attractive option for industries seeking to transition to cleaner energy sources. In recent years, liquefied natural gas (LNG) has gained popularity as a cleaner alternative to coal and oil, reducing CO2 emissions by 25-40%. However, biomethane offers an even more sustainable solution.

MOL’s press release highlights the importance of this study, stating, “Biomethane is an effective energy source for the ultimate goal of decarbonization because it can be used in current infrastructure for transport and consumption. The six organizations participating in the collaboration will bring their respective knowledge and experience to this study.”
The potential benefits of biomethane are manifold. First, its use could significantly reduce greenhouse gas emissions from the shipping industry, one of the world’s largest contributors to global warming. By adopting biomethane, MOL could achieve substantial reductions in both emissions and fuel costs. Moreover, the production of biomethane could aid in the better management of organic waste in Japan, reducing landfill waste and mitigating potential environmental hazards.
The timing of this study is particularly opportune as MOL Sunflower, MOL’s subsidiary, is expanding its ferry services. The company currently operates an 18-hour ferry route between Hokkaido and Tokyo, and two new LNG-fueled vessels are expected to join its fleet by 2025. Incorporating biomethane into this expansion could further enhance the environmental sustainability of these operations.

Japan is not alone in recognizing the potential of biomethane as a clean fuel. Countries worldwide are increasingly exploring its use in the fight against global warming. France’s CMA CGM, a global shipping giant, has already taken significant steps in this direction, introducing its first biomethane-powered shipping service in 2021.
In a recent milestone, Titan Clean Fuels and STX Group completed a record-breaking ship-to-ship delivery of 2,200 metric tons of liquefied biomethane to a Hapag-Lloyd vessel at the Port of Rotterdam. This event underscores the growing global interest in biomethane as a viable alternative to fossil fuels.
The carbon footprint of biomethane depends largely on its source. Biomethane derived from organic waste, such as cow dung, can be a powerful tool in mitigating climate change. In contrast, biomethane from fossil sources offers limited environmental benefits.
Japan continues its experiment with cow-dung-powered ships, the world will be watching closely. If successful, this initiative could pave the way for broader adoption of biomethane in the maritime industry and beyond. The study’s findings could serve as a blueprint for other nations striving to meet their own climate goals.
