船舶的空气污染物和温室气体排放。

In the maritime sector, the International Maritime Organization adopted a GHG reduction strategy in 2018, aiming to achieve zero emissions from international marine transportation as early as possible this century, as well as to improve emissions per unit of transport by at least 40% by 2030 and reduce total GHG emissions by at least 50% by 2050, both compared to 2008 levels. Recently, there have been discussions about moving up the schedule. At the same time, there are movements towards reducing NO _X emissions in urban areas, environmentally protected areas, and large ports especially in Europe and the U.S. Unlike internal combustion engines, hydrogen fuel cells emit only water and do not emit any greenhouse gases such as carbon dioxide (CO ₂ ) or air pollutants such as nitrogen oxides (NO _X )… On the other hand, it is necessary to develop new technology to comply with the operating environment and safety regulations of ships. In addition, to commercialize the technology, it is necessary to consider hydrogen refueling methods.

​ “氢” 作为 下一代能源 的好处

从2015年开始的三年时间里，洋马受国土交通省委托，与国家海事研究所等合作，制定了《氢燃料电池船舶安全指南》大纲。之后，洋马开发了海上氢燃料电池系统，并利用丰田汽车公司的燃料电池汽车“MIRAI”的部件用试验船进行了验证测试。洋马集团各部门的船体设计、电气设计和控制设计工程师参与了这艘试验船的开发。根据安全导则的要求安装了燃料电池和高压氢气罐，安装了燃料电池和高压氢气罐。同时，还开发了协调和控制燃料电池、锂离子电池和电机运行的电源管理系统。
