Hitachi Zosen Corporation. (Osaka
City, Osaka, Sadao Mino, President & CEO, hereinafter “Hitachi Zosen”) and
Nippon Yusen Kabushiki Kaisha (Chiyoda-ku, Tokyo, Representative: Takaya Soga,
President, hereinafter “NYK”) are pleased to announce that the jointly proposed "Development of N2O Reactors for
Ammonia-Fueled Carrier" has been selected by the New Energy and Industrial
Technology Development Organization (NEDO) as a "Next Generation Ship
Development" which was additionally invited in November 2023 as a part
of Green Innovation Fund Project (hereinafter “GI Fund Project”).
In July 2023, the International Maritime Organization (IMO) set a target of
achieving virtually no greenhouse gases (GHG) emitted from international marine
transportation by around 2050. In order to achieve this target, R&D of
next-generation ships that do not emit GHG is an urgent task, and in
particular, the development of technology to convert ship fuel from
conventional fossil fuels to alternative fuels such as ammonia, which emits no
carbon dioxide (hereinafter referred to as CO2) when burned, is being promoted
as a GI Fund project.
The project aims to develop a catalytic
removal system for nitrous oxide ('N2O') emitted when ammonia is used as fuel
('N2O Reactor'). N2O's global warming potential?? is about 300 times that
of CO2, and it is essential to reduce N2O emissions in order to realize
ammonia-fueled vessel carriers that are highly effective in reducing GHG
emissions. By developing and disseminating
N2O reactors, we are aiming for the
early realization of Carbon Neutral in maritime transport.
Hitachi Zosen has a strong track record and know-how in catalytic technology,
including the development of marine vessel SCR (Selective Catalytic Reduction)
system for removing nitrogen oxides (NOx) in marine engines. In this business,
we will develop catalysts and equipment to reduce N2O for marine 2-stroke
engines?? and optimize equipment layout.
NYK will install N2O reactor developed by Hitachi Zosen on the ammonia-fueled
carrier scheduled to be completed in November 2026, and will be in charge of
safety and performance verification by demonstration navigation.
ClassNK, as a partner organization, will conduct safety verification of N2O
reactors and basic research on the development of international guidelines.
Three parties will lead the world in environmental
technology by actively challenging the research and development of next-generation
ships that do not emit GHGs and
contribute to the reduction of GHGs emitted by international marine
transportation.
