NYK will deploy a binary cycle power generation system on a newly constructed Panamax* bulk carrier to be operated by the company. The system will generate electricity from the exhaust heat emitted by the marine engine's air cooler. In addition, NYK will provide the system developer with operational data from the ship to help improve the product.

A binary cycle power generation system for ships has been jointly developed by Kobe Steel, Ltd., Miura Co. Ltd., and Asahi Shipping Co. Ltd. and has received approval as “environmental equipment” from Japan’s ship classification society Nippon Kaiji Kyokai (ClassNK). The generated electric power will serve as auxiliary power and will reduce CO2 emissions by up to 2.3 percent by decreasing fuel consumption.

NYK has previously equipped Capesize** bulk carriers and pure car and truck carriers with hybrid power supply systems to utilize exhaust heat from engine exhaust gas. However, the binary cycle power generation system will give the opportunity to reuse engine exhaust heat to generate electricity on Pamamax vessels.

As an organization that conducts business activities globally, the NYK Group has positioned global environmental conservation as one of its most important issues and will continue its efforts to make use of advanced environmentally consciousness technology.

* Panamax: 60,000 – 119,999 dwt

** Capesize: Over 120,000 dwt


NYK has been selected for the Dow Jones Sustainability Indices (DJSI)* for a 15th straight year.

The DJSI, which is a major global index for companies engaging in socially responsible investment (SRI),** is composed of select sustainability-driven companies from over 3,400 world-wide companies invited to participate in a selection process consisting of an in-depth analysis of economic, environmental, and social criteria, such as corporate governance, risk management, water-related risks, and stakeholder relations.

As well as the FTSE4Good Index for which NYK was also selected for a 15th straight year in June this year, the DJSI is an important selection standard for investors who value corporate social responsibility and sustainability.

NYK, as a good corporate citizen, will continue to take an active role in social issues to contribute to the achievement of a better global society.

  * Dow Jones Sustainability Indices (DJSI): The results of the annual DJSI review are announced jointly by S&P Dow Jones Indices LLC, the world's largest global resource for index-based concepts, data, and research, and RobecoSAM, a Switzerland-based company that conducts assessments of corporate sustainability.

 ** Socially Responsible Investment (SRI): investment based on not only a company’s economic performance but also its environmental measures, compliance with laws, and other corporate social responsibility factors as evaluation criteria.
