LNG fuel supply initiatives

The NYK Group has positioned the decarbonization of shipping as an urgent issue and has been the world's first company to put LNG-fueled ships to practical use in an effort to shift to zero-emission fuels.
Please refer to the related link for details of our LNG fuel initiatives.

More Information:

Heavy fuel oil is currently the primary marine fuel used. However, its usage results in environmental destruction, including climate change. LNG (liquefied natural gas), however, is a next-generation fuel that can significantly reduce CO2 (carbon dioxide), NOx (nitrogen oxides) and SOx (sulphur oxides) emissions. We have positioned marine LNG as a bridging solution* to the practical use of zero-emission fuels, and we are developing our LNG fuel supply business to be a front-runner in the industry.
As a shipping company, we can contribute not only on the LNG-fuel-demand side but also on the supply side. We are expanding our business globally in key locations and building an LNG-fuel value chain.

  • *NYK is positioning LNG fuel as a bridge solution until marine fuels that have a lower environmental impact, such as hydrogen and ammonia, can be utilized to realize future zero-emission vessels.

The world's first LNG bunkering vessel

Green Zeebrugge

In 2017, we took delivery of the world's first LNG bunkering vessel, Green Zeebrugge, as a preparatory step to deal with environmental issues. We have been involved in an LNG bunkering business in Northern Europe based in the port of Zeebrugge (Belgium), and we are contributing to the development of the value chain for next-generation fuel vessels by deploying them in the fleet of our subsidiary UECC. In the future, we will also supply zero-emission fuels to help achieve a decarbonized society.

Japan's New Energy and Industrial Technology Development Organization (NEDO) has approved NYK Line's participation in a demonstration project for the commercialization of vessels equipped with a domestically produced ammonia-fueled engine as part of the Green Innovation Fund project.*
The demonstration project aims to use ammonia as fuel to significantly reduce greenhouse gas (GHG) emissions during voyages and thus introduce an ammonia-fueled vessel for the good of society earlier than 2030.
NYK will eventually work toward the goal of achieving zero emissions from ships in the future.

  • *Green Innovation Fund project
    A 2 trillion yen fund created in NEDO to significantly accelerate current efforts such as structural transformation of the energy and industrial sector and innovation through bold investment toward carbon neutrality by 2050. The fund provides continuous support from R&D and demonstration to social implementation for up to 10 years for companies that share ambitious and concrete goals with the public and private sectors and tackle them as management issues. NEDO provides support mainly in 14 priority areas for which action plans are being formulated in the green growth strategy.

Advanced Hydrogen Energy Chain Association for Technology Development (AHEAD)

In order to realize a hydrogen society as early as possible, we have been participating in the Advanced Hydrogen Energy Chain Association for Technology Development (AHEAD) since 2017.
