Seven Japanese Firms Plan Integrated Ammonia Fuel Supply Chain for Car Carriers by 2030

Summary

Seven Japanese companies are planning an integrated marine ammonia fuel supply chain centred on Japan’s Chubu region, combining green ammonia production, fuel sales, bunkering infrastructure and ammonia-fuelled car carriers. NYK and Kawasaki Kisen Kaisha (K Line) will each introduce two dual-fuel ammonia-powered car carriers by 2030, while a dedicated bunkering vessel and new terminal facilities will support fuel distribution. The companies describe the initiative as the first commercial supply chain of its kind, although project costs, vessel specifications and planned ammonia volumes have not been disclosed.

Seven Companies Coordinate Ammonia Fuel Infrastructure and Vessel Operations

Seven Japanese companies are developing an integrated system to support the commercial use of ammonia as a marine fuel, connecting fuel production and supply with bunkering operations and vessel deployment. The project will be centred on Japan’s Chubu region and is intended to establish a coordinated supply chain for ammonia-fuelled shipping.

The participating companies are NYK, Kawasaki Kisen Kaisha (K Line), JERA, Imabari Shipbuilding, Shin Kurushima Dockyard, Nihon Shipyard and Kyokuyo Shipyard. Their respective roles cover vessel ownership and operation, fuel production, shipbuilding, bunkering infrastructure and fuel sales.

The companies describe the initiative as the first commercial supply chain integrating these elements around ammonia as a marine fuel. However, the project’s total investment, expected fuel volumes and detailed vessel specifications have not been announced.

Four Ammonia-Fuelled Car Carriers Planned for 2030

NYK and K Line will each introduce two car carriers equipped with dual-fuel ammonia engines, bringing the planned fleet to four vessels. The ships are scheduled for completion in 2030, with Imabari Shipbuilding, Shin Kurushima Dockyard and Nihon Shipyard responsible for their design and construction.

The vessels are intended to undertake trans-Pacific voyages using ammonia as their sole fuel. They are also expected to transport finished vehicles for customers including Toyota Motor Corporation.

The deployment of the four ships is a central component of the initiative, linking demand for ammonia fuel to the development of production, distribution and bunkering infrastructure.

JERA to Develop Green Ammonia Supply and Terminal Facilities

JERA will lead the green ammonia production and supply component of the project. Renewable energy from regions including India is expected to contribute to green ammonia production, although the companies have not disclosed specific sourcing arrangements, suppliers or planned volumes.

JERA already operates a low-carbon ammonia value chain that includes activities at the Hekinan Thermal Power Station. Its existing infrastructure also includes a system for loading and unloading ammonia tank trucks.

As part of the new initiative, JERA will construct additional ship-loading facilities at the ammonia receiving terminal adjacent to the Hekinan station. The facilities are intended to support a stable ammonia supply for the dedicated bunkering vessel.

The development will connect ammonia handling infrastructure at the terminal with the fuel requirements of the planned car carriers.

Dedicated Ammonia Bunkering Vessel to Support Ship-to-Ship Transfers

Kyokuyo Shipyard will design and build a dedicated ammonia bunkering vessel, which is also scheduled for completion in 2030. NYK will own and operate the vessel.

The bunkering ship will be designed to transfer ammonia directly between vessels, providing a dedicated means of supplying fuel to ammonia-powered ships.

Given ammonia’s toxicity and corrosiveness, the vessel will incorporate leak-prevention systems and equipment intended to address the hazards associated with handling the fuel. The project’s operational arrangements will therefore need to account for the specific safety requirements of ammonia bunkering.

NYK and K Line to Establish Fuel Sales Joint Venture

NYK and K Line will establish a joint venture to sell ammonia fuel, completing the planned integration of production, distribution, bunkering and vessel operations.

The fuel sales venture is intended to connect the supply side of the project with shipping customers. NYK, which has experience with LNG-fuelled carriers, will also operate the dedicated ammonia bunkering vessel.

The companies have not yet disclosed the joint venture’s ownership structure, commercial terms or planned fuel sales volumes.

Implications for the Maritime Fuel Transition

The initiative brings together several elements required for the wider adoption of ammonia as a marine fuel: suitable vessels, a dependable fuel supply, dedicated bunkering capacity and a commercial sales structure.

Coordinating these elements within a single project could help address the challenge of developing fuel infrastructure alongside demand from ship operators. However, commercial deployment will depend on the availability and cost of ammonia, infrastructure readiness, vessel performance and the implementation of appropriate safety and regulatory arrangements.

The planned use of renewable energy from regions including India also identifies a potential connection with future green ammonia exports. No Indian production partners, supply agreements or export volumes have been announced, so the extent of India’s participation remains unclear.

What Happens Next?

Key details to watch include the specifications and capacities of the four car carriers, the bunkering vessel’s design, green ammonia production volumes and sourcing arrangements, and the investment required for terminal and bunkering infrastructure.

Further information on the fuel sales joint venture, commercial supply agreements and applicable regulatory approvals will also be important in assessing the project’s readiness for operation by 2030.
