NYK Begins Continuous Use of Bio-LNG Fuel on Car Carriers

Significantly reducing GHG emissions through clean fuel, accelerating the decarbonization of shipping

23 July 2025

As part of its commitment to realizing a decarbonized society, NYK has commenced the continuous use of bio-LNG fuel on its LNG-powered car carriers. The bio-LNG is supplied by Titan Supply B.V. (Titan)* at the port of Zeebrugge in Belgium. The first vessel to receive the fuel was Daisy Leader on June 15, and the second was Sumire Leader on July 18.

What is bio-LNG fuel ?
Bio-LNG, also known as liquefied biomethane, is purified liquefied methane gas (biogas) produced from biomass feedstock, such as animal manure and food wastes. By capturing methane that would otherwise be released into the atmosphere, greenhouse gas (GHG) emissions over the entire life cycle can be significantly reduced. The bio-LNG fuel supplied by Titan under the mass balance method* is recognized as carbon neutral in the whole process from production to consumption (well-to-wake) and is ISCC EU certified, an international standard for sustainability, ensuring compliance with EU regulations and traceability throughout the supply chain.

Future Prospects
NYK has long been at the forefront of efforts to decarbonize the shipping industry through the operation of LNG-fueled vessels and usage of biofuel. In November 2023, the NYK Group Decarbonization Story was released, outlining the goal of achieving net-zero GHG emissions by 2050. The expanded use of bio-LNG fuel is one of the key initiatives to achieve this goal. NYK remains dedicated to proactively utilizing bio-LNG and other environmentally friendly fuels to pave the way toward a sustainable future for marine transportation.

Comments from Titan CEO Niels den Nijs
I would like to express my sincere respect for NYK's decision to start using bio-LNG fuel. Titan's mission is to provide solutions to help the shipping industry transition to cleaner fuels. We are very pleased to be able to accelerate our decarbonization efforts together with NYK through this replenishment.

Comments from NYK Fuel Group General Manager Kaori Takahashi
We are very pleased to begin the continued use of bio-LNG fuel. Bio-LNG fuel is a highly effective option for decarbonizing the shipping industry, and we will continue actively promoting its use. This initiative will be an important step toward reducing our environmental impact further and achieving a sustainable future.

* Titan Supply B.V. is a Dutch company specializing in the supply of LNG fuel for ships. Operating primarily in Europe, Titan also supplies bio-LNG to promote the adoption of low-environmental-impact fuels.

** Mass balancing is an administrative system that tracks the environmental attributes of bio-methane fuel throughout the supply chain, allowing it to be blended with conventional LNG fuels while still crediting its emissions reductions.
