Zero GHG Emissions

The Group, which promotes ESG management, created the Green Business Group in April 2019 to create new value for the next generation under the theme of renewable energy.
We are strengthening various initiatives, including next-generation fuels such as hydrogen and ammonia, the offshore wind power generation business, the LNG fuel supply business, CO2 transportation, and carbon credits.
In April 2022, NYK launched its new "NYK GREEN EARTH" brand to consolidate its efforts to generate new value for low-carbon and decarbonization through green business. Through activities aimed at realizing a decarbonized society, we aim to build a new energy value chain while ensuring the sustainable development and growth of the company and society.

Initiatives to develop next-generation fuels

The NYK Group is working to promote the use of next-generation fuels such as hydrogen and ammonia to achieve Japan's goal of reducing greenhouse gas emissions to virtually zero by 2050.

Demonstration project begins for commercialization of vessels equipped with domestically produced ammonia-fueled engine

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 mainly provides support 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)

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.
In 2020, AHEAD was selected by the NEDO grant program and completed the world's first demonstration of an international hydrogen supply chain using MCH (methylcyclohexane).
Since 2021, AHEAD has started to supply MCH produced in Brunei to ENEOS Corporation's demonstration project in Japan.


Challenging new fields requires a combination of "technological capabilities" and "collaborative creation," and collaborative creation is the driving force behind innovation. We are participating in the below networks to create further collaborative creation.
We will continue our efforts to decarbonize not only the shipping industry but also society as a whole through collaborative creation with world-class partners.

Examples of collaborative creation with partners

  • Clean Fuel Ammonia Association
  • Hydrogen Council
  • The Maersk Mc-Kinney Moller Center for Zero Carbon Shipping
  • Getting to Zero Coalition
  • Hydrogen Value Chain Development Council

Offshore wind market initiatives

The offshore wind market in Japan is expected to expand rapidly. In addition to the technological capabilities and knowledge of Japanese regulations and legal systems that we have cultivated over many years through our shipping business, the NYK Group is taking full advantage of the knowledge that we have gained through our offshore business and the nationwide group companies that we have established throughout Japan to become actively involved in the entire offshore wind value chain.

Jack-up vessel (Self-Elevating Platform Vessel)

Jack-up vessel

In cooperation with Van Oord Offshore Wind BV in the Netherlands, NYK is making efforts to own and operate a jack-up vessel in Japan for use in the installation of offshore wind turbines and foundations while meeting Japanese local requirements such as vessel-flag restrictions.

CTV (Crew Transfer Vessel)

In cooperation with Northern Offshore Group AB (NOG) in Sweden, NYK is making efforts to own and operate crew transfer vessels (CTVs) for the offshore wind business in Japan, with the aim of building a domestic CTV based on NOG's original vessel design. In addition, NYK will establish a nationwide CTV service network for the future development of the offshore wind business in Japan. As part of the collaboration with NOG, NYK purchased a new CTV named "Energizer" in 2022. The CTV is currently being operated in Europe by NOG subsidiary Northern Offshore Services AS (NOS), with which NYK is currently promoting personnel exchanges.

CTV "Rera As"

NYK has concluded a time charter contract with Siemens Gamesa, the world-leading provider of wind power solutions, for a CTV for an offshore wind power generation facility.
The CTV is named "Rera As" and started operation in Ishikari, Hokkaido, in June 2023.
It is the first CTV owned and managed by the NYK Group inside Japan.

Maritime consulting services

Maritime simulator

Japan Marine Science Inc. (JMS), an NYK Group company, provides comprehensive maritime consulting services. For the offshore wind business, JMS offers site environment assessments, feasibility-study support for wind-turbine scale and specifications, use of a maritime simulator to examine vessel safety during and after the installation of wind turbines, diving inspections during wind turbine operation, training via simulator for workboat crews, and marine monitoring systems.

Transportation business for offshore wind business

Deck carrier

Having a history of more than 100 years, NYK Bulk & Projects Carriers Ltd. (NBP) is Japan's leading ocean carrier of project and heavy-lift cargo.
NBP has a track record in overseas offshore wind projects for the transport of nacelles (generators) via a heavy lifter and jackets (foundations) by deck carriers.
In September 2021, heavy lifters with 800 mt lifting capacity were added to the NBP fleet, and the company is actively participating in offshore wind projects in Japan.

Other initiatives

To achieve decarbonization not only of shipping but also of society as a whole, we are actively involved in renewable energy projects across the entire energy value chain. Here we would like to introduce some of the specific projects we are involved in.

Investment in Tsubame BHB

In June 2021, NYK decided to invest in Tsubame BHB Co. Ltd., a venture company originating at the Tokyo Institute of Technology.
Tsubame BHB is working on the practical application of an on-site ammonia synthesis system invented by Professor Emeritus Hideo Hosono that uses a special catalyst technology to produce a required amount of ammonia at a required location.
With this investment, NYK will support the commercialization of Tsubame BHB's innovative technology and contribute to the reduction of environmental impact.

Joining forces with BP to help decarbonize hard-to-abate sectors

We have signed a memorandum of understanding with BP, a major global marine fuel and lubricants supplier, to collaborate on future fuels and transportation solutions to help industrial sectors, including shipping, decarbonize. The companies will collaborate and identify opportunities to help transition from current marine fuels to alternatives such as LNG, biofuels, and methanol, and to develop future fuels such as ammonia and hydrogen. We will also consider potential marine transportation and other solutions to reduce CO2, and explore participation in the supply chains for ammonia and hydrogen to be used in heavy industry and power generation to help those sectors to decarbonize.
