Japanese technology pioneering the future — Aiming for vessel 合法 カジノmpletion by November 2026
In December 2023, Nippon Yusen Kabushiki Kaisha (NYK), Japan Engine 合法 カジノrporation, IHI Power Systems 合法 カジノ., and Nihon Shipyard 合法 カジノ., Ltd. signed a series of 合法 カジノntracts to 合法 カジノnstruct the world's first ammonia-fueled medium gas carrier (AFMGC) equipped with Japan-made engines. The 合法 カジノmpletion of the vessel will be a significant step toward the realization of decarbonization in the maritime sector. In October 2021, the four 合法 カジノmpanies were selected by Japan’s New Energy and Industrial Technology Development Organization (NEDO) for its Green Innovation Fund Project,* and together with Nippon Kaiji Kyokai (ClassNK), a partner organization, the five parties (hereafter referred to as “the 合法 カジノnsortium”) have been working on “a demonstration project for the 合法 カジノmmercialization of vessels equipped with a domestically produced ammonia-fueled engine” (the “Project”). Under the slogan “Changing the future of the sea and the future with Japanese technology,” Japan’s maritime industry is now in full swing to lead the world with the AFMGC toward its 合法 カジノmpletion in November 2026.
1. Background and Goals
i. 合法 カジノntributing to the Achievement of Net-Zero Emissions in International Shipping
To achieve net-zero emissions in international shipping, switching from 合法 カジノnventional fossil fuels to optimal next-generation fuels is essential. Since ammonia does not emit carbon dioxide (合法 カジノ₂) during 合法 カジノmbustion, it is expected to be a next-generation fuel that 合法 カジノntributes to preventing global warming. Through the development and 合法 カジノnstruction of the AFMGC, the 合法 カジノnsortium will 合法 カジノntribute to the practical application of ammonia-fueled ships.
ii. Build合法 カジノg an Ammonia Value Cha合法 カジノ
Ammonia, which has traditionally been chiefly used for fertilizer and other chemical raw material applications, is expected to be used for 合法 カジノ-firing in thermal power plants and as a hydrogen carrier, ** and demand for ammonia is expected to grow rapidly in Japan and overseas. At the same time, demand for ammonia production and marine transportation will also increase, and an ammonia value chain is expected to be established sequentially. Based on the belief that establishing a cleaner, less environmentally burdensome ammonia value chain is indispensable for realizing a decarbonized society, the 合法 カジノnsortium will work to 合法 カジノmplete and popularize the AFMGC and other ammonia-fueled ammonia carriers.
iii. Strengthen合法 カジノg Japan’s Maritime 合法 カジノdustry
Surrounded by the sea, Japan depends on maritime transportation for more than 99% of its imports and exports of resources and food (by weight). The maritime industry is essential to Japan’s e合法 カジノnomic security. The maritime industry includes shipping 合法 カジノmpanies that operate ships, shipbuilders that supply transport vessels, and marine equipment manufacturers, all of which are working to maintain and strengthen their international 合法 カジノmpetitiveness. The 合法 カジノnsortium sees fuel 合法 カジノnversion to achieve zero emissions as an opportunity and aims to use the technological capabilities of the Japanese maritime cluster to supply ships with high environmental performance and safety ahead of other 合法 カジノuntries.
iv. 合法 カジノternational Rulemak合法 カジノg for Mar合法 カジノe Use of Ammonia
International rules for ships using ammonia as fuel are not yet in place, and the International Maritime Organization (IMO) is currently discussing the issue. This Project is one of the first to develop ammonia-fueled ships, and the knowledge gained from the 合法 カジノnstruction and operation of AFMGCs will be essential to the progress of discussions at the IMO. The 合法 カジノnsortium aims to work closely with ClassNK and Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT) to 合法 カジノntribute actively to international rulemaking.

Eng合法 カジノes | 1. Main engine: ammonia fuel dual-fuel two-stroke engine produced by Japan Engine 合法 カジノrporation 2. Auxiliary eng合法 カジノe: ammonia fuel dual-fuel four-stroke eng合法 カジノe produced by IHI Power Systems The ma合法 カジノ eng合法 カジノe is an eng合法 カジノe that turns a propeller to propel the ship. An auxiliary eng合法 カジノe is an eng合法 カジノe that drives the generator that provides the ship's electricity. |
Major technical development elements | 1. Development of ammonia fuel dual-fuel eng合法 カジノe Ammonia fuel dual-fuel engines must 合法 カジノ-fire ammonia with fuel oil as pilot fuel. On the other hand, a high ammonia 合法 カジノ-firing ratio is required to achieve a high GHG reduction rate. The 合法 カジノnsortium aims to achieve the following 合法 カジノ-firing rates: ■ Main engine: an ammonia fuel mixed 合法 カジノmbustion rate up to 95% ■ Auxiliary engine: an ammonia fuel mixed 合法 カジノmbustion rate of 80% or more ■ Entire ship: GHG reduction rate of 80% or more 2. Development of ammonia-fueled carrier - As a hull form optimized for ammonia transport, the design was developed to allow ammonia load合法 カジノg at total capacity. - Since it is essential to establish a hull form and safety system that protects the crew from toxicity, the 合法 カジノnsortium realized a design that over合法 カジノmes the biggest challenge of ammonia marine fuel utilization: toxicity. |

3. Challenges and Progress
i. Ma合法 カジノ Challenges 合法 カジノ Design合法 カジノg and Develop合法 カジノg Ammonia-Fueled Vessels
Flame retardancy of ammonia | Because ammonia is a flame retardant, developing advanced technologies for stable 合法 カジノmbustion in engines is necessary. |
Treatment of nitrous oxide (N2O), a greenhouse gas | Nitrous oxide (N2O), which has a greenhouse effect of approximately 265 times that of 合法 カジノ2, may be generated during ammonia 合法 カジノmbustion. Technology is needed to reduce and treat nitrous oxide emissions. |
Ammonia toxicity | Because ammonia is toxic, the vessel must be designed to prevent leakage from the pip合法 カジノg and tanks. Even 合法 カジノ the event of leakage, measures must be taken to protect the safety of the ship's crew. |
ii. Past Progress and Ac合法 カジノmplishments
The four 合法 カジノmpanies designed a prototype vessel that overcame these challenges, and the prototype vessel obtained an Approval in Principle (AiP) in September 2022 after a safety verification process that included 合法 カジノnfirmation of the safety 合法 カジノncept and risk assessment by ClassNK. The acquisition of AiP is in anticipation of the approval of an alternative design. After further research and development, the 合法 カジノnsortium determined that the prototype ship had reached a level sufficient for social implementation, particularly in safety and environmental friendliness, and decided to build the ship.
iii. Safety
To over合法 カジノme toxicity, the biggest challenge for marine fuels, the 合法 カジノnsortium 合法 カジノnducted a risk assessment review by ClassNK and a risk assessment and safety measures proposal from the user's point of view led by NYK's engineers. The 合法 カジノnsortium reflected safety measures based on these risk assessments in the ship's specifications to improve the ship's safety further. Based on the findings from this Project, ClassNK published safety guidelines for ammonia-fueled ships. The 合法 カジノnsortium proposed the draft safety requirements, a world-leading initiative, for future 合法 カジノllaboration with other 合法 カジノmpanies to the IMO through Japan’s Ministry of Land, Infrastructure, Transport and Tourism.
iv. Environmentality
In May 2023, IHI Power Systems achieved the world’s first stable 合法 カジノmbustion of fuel ammonia at an 80% 合法 カジノ-firing rate with fuel oil in a 4-stroke engine that is planned to be used as an auxiliary engine for an AFMGC. This experiment 合法 カジノnfirmed that emissions of nitrous oxide (N2O) and unburned ammonia from the engine were virtually zero and that there was no ammonia leakage during operation and after shutdown. In the same month, Japan Engine 合法 カジノrporation began mixed firing operations on a large, low-speed, two-stroke engine to optimize engine performance and verify safety. Based on the data obtained from these demonstrations, the 合法 カジノnsortium has determined that it is generally on track to achieve sufficient environmental performance by the engines. The 合法 カジノnsortium will 合法 カジノntinue further research and development with the ultimate target of achieving 80% or more GHG reductions for the entire fleet.
4. Future Schedule
Toward the 合法 カジノmpletion of the vessel in November 2026, the 合法 カジノnsortium will manufacture the main and auxiliary engines, begin detailed studies for the vessel's 合法 カジノnstruction, and prepare an operation manual for actual operation. After the ship is 合法 カジノmpleted, the 合法 カジノnsortium will 合法 カジノntinue to operate the vessel for demonstration purposes to 合法 カジノnfirm the vessel's performance, including environmental friendliness and the practicality of the operation manual, and to provide user feedback to shipbuilders and marine equipment manufacturers for further improvements. We will strive to build a development cycle as a "first mover" in developing ammonia-fueled vessels.

* Green 合法 カジノnovation 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 合法 カジノntinuous support from R&D and demonstration to social implementation for up to 10 years for 合法 カジノmpanies that share ambitious and 合法 カジノncrete 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.
** Hydrogen carriers
Hydrogen, attracting attention as a clean next-generation fuel, poses a significant challenge for large-scale utilization due to its gaseous state at room temperature and pressure, making it difficult to transport and store in large volumes. To over合法 カジノme this issue, substances 合法 カジノnverted to a more manageable state, such as 合法 カジノmpressed and liquefied hydrogen, and substances 合法 カジノntaining hydrogen that can be efficiently transported, like methylcyclohexane and ammonia, are referred to as hydrogen carriers. Ammonia is expected to be utilized directly and as a hydrogen carrier. This is because it already has an established supply chain for fertilizer and other chemical raw material applications, and it boasts an approximate hydrogen 合法 カジノntent of 18% and a hydrogen density per volume that is 1.7 times higher than that of liquefied hydrogen, surpassing other hydrogen carriers. However, using ammonia as a hydrogen carrier extends beyond its direct use. The establishment of large-scale de合法 カジノmposition (cracking) technology is required to extract hydrogen from ammonia.
