Mitsubishi Kakoki Participates in Trial on Long-Term Use of High-Purity Biodiesel Fuel

Mitsubishi Kakoki Kaisha, Ltd. (President: Toshikazu Tanaka; Head Office: Kawasaki, Japan; hereinafter "MKK") will cooperate in technical verification using its marine oil purifier as part of a long-term trial of biofuel (B100*) to be conducted on a pure car and truck carrier (PCTC) operated by Nippon Yusen Kabushiki Kaisha (President: Takaya Soga; Head Office: Chiyoda-Ku, Tokyo; hereinafter "NYK Line").

In the maritime sector, biofuel blends such as B24 and B30**, made from FAME derived from feedstocks like used cooking oil and blended with very low sulfur fuel oil (VLSFO), are being introduced as drop-in fuels. This initiative aims to assess the long-term impact of continuous use of high-purity biodiesel fuel (B100), considered a promising means of reducing greenhouse gas emissions, on the performance and operation of a vessel's fuel supply system, using an NYK Line-operated pure car and truck carrier (PCTC) over a one-year period.

MKK participated in "Project LOTUS," led by NYK Line and the Global Centre for Maritime Decarbonisation (GCMD), which examined the long-term use and storage of B24 biofuel, with results announced in September 2025. Through this project, MKK helped confirm technical safety and contributed to the disclosure of technical findings on biofuel use and storage. In this initiative, as in Project LOTUS, MKK will provide technical verification and support using the Mitsubishi Selfjector (marine oil purifier) installed on the vessel. Through a one-year trial of high-purity biodiesel fuel, MKK aims to gain further insights to improve the reliability and maintainability of oil purifiers.

Biofuels are widely recognized as one of the leading methods for reducing greenhouse gas emissions. MKK has supported various onshore and onboard biofuel tests and contributed to establishing effective methods for operating oil purifiers. Going forward, MKK will continue to leverage its long-standing expertise in marine oil purifiers to support safe vessel operations and contribute to a sustainable, decarbonized society.

* B100: A fuel consisting of 100% biofuel. In this trial, B100 primarily refers to FAME (Fatty Acid Methyl Ester) derived from feedstocks such as used cooking oil.
** B24 and B30: Fuels consisting of conventional heavy fuel oil blended with approximately 24% and 30% biofuel, respectively.

Through the initiative covered in this press release, Mitsubishi Kakoki will contribute to achieving the following Sustainable Development Goals (SDGs):

Goal 7 Affordable and clean energy
Goal 12 Responsible consumption and production
Goal 13 Climate action
