Targeting The Utilization Of Diverse Energy Resources And Realization Of A Low-Carbon SocietyContributing To The Utilization And Development Of Hydrogen Energy In Industrial Fields Through Development And Popularization Of Hydrogen Fuel Cells

Social Challenges Relating to Yanmar Industries / Values that Yanmar Can Provide

In Japan, most of the primary energy supplied domestically is dependent on fossil fuels from the Middle East. In addition to coal and petroleum, the dependence on fossil fuels accounts for 89% of the total primary energy, as the consumption of LNG (Liquefied Natural Gas) used for thermal power plants and others has increased since the Great East Japan Earthquake. Furthermore, the energy self-sufficiency rate in Japan for primary energy is only 8.3%.

In order to fundamentally solve the worsening problem of global warming, countries around the world have set targets to reduce greenhouse gas emissions under international frameworks such as SDGs (Sustainable Development Goals), the Paris Agreement, and are accelerating efforts to realize the goals. Japan has also set a reduction target of 26% by 2030 compared to 2013.

As one of the new energy sources, hydrogen is expected to simultaneously solve the issues of assuring the energy security and reducing greenhouse gas emissions. Hydrogen can be generated from various energy sources such as renewable energy and has the environmental characteristic of not emitting CO2 when used. Also, it is able to act as an energy carrier to store, transport and use energy. Yanmar is promoting R&D towards utilization of hydrogen energy. In order to contribute to the deployment of fuel cells to small vessels, we conduct pilot programs aimed at establishing safety guidelines with countries and other enterprises.

Pilot test confirmed the safty of our 60 KW hydrogen fuel cell system installed in a small ship

Among mobility, maritime is considered to be a field where it is difficult to reduce carbon emissions, and promotion of electrification including utilization of fuel cells is considered to be effective for reducing CO2 emissions. YANMAR formed a consortium with the National Maritime Research Institute (NMRI) - National Institute of Maritime, Port and Aviation Technology, Harbor and Aeronautical - and the Japan Ship Technology Research Association, and conducted a ship test from February to March, 2018 as part of the "Research and consideration project for formulating safety guideline for hydrogen fuel cell ship" ordered by Ministry of Land, Infrastructure, Transport and Tourism.

This project has been implemented on a three-year plan beginning in 2015. In the final year, 2017, the ship test was conducted based on the results obtained from previous basic tests such as salt damage countermeasure and oscillation test of fuel cell. The ship test was carried out mainly by YANMAR and NMRI, and was carried out by installing a 60 kW maritime fuel cell system manufactured by Yanmar and a lithium-ion battery system manufactured by Uzushio Electric Co., Ltd. on the testing ship. As a result, we can confirm the validity of the safety requirement required for the fuel cell system and the storage battery system installed in the fuel cell ship. The test result was submitted to the Ministry of Land, Infrastructure, Transport and Tourism to contribute to the study of "Guidelines for safety of hydrogen fuel cell-powered boats".

We will continue to conduct research and pilot programs aimed at high power and compactness of marine fuel cell systems for the future commercialization of hydrogen fuel cell ships. As a potential market for hydrogen fuel cell ships, small coastal navigation vessels such as tourist boats and excursion boats in urban areas are assumed. After considering the possibility of introduction to the market, we will aim to implement this starting from those with high cost-effectiveness.

The environmental regulations of YANMAR business domains including maritime field will become increasingly strict in the future. Nevertheless, we view this change in the environment as a great opportunity to realize A Sustainable Future, not as a threat. Hydrogen utilization in the maritime field has technical and cost issues such as legal improvement, infrastructure improvement, durability and reliability of fuel cells, but with the new technology called fuel cell technology, all the company's members are united in the common goal of making YANMAR the industry leader. We will continue to develop and pilot test technologies for the practical application of fuel cell ships, and will contribute to efforts such as making rules, making companions and making infrastructure by utilizing frameworks of national projects.
