Japanese shipping giant Mitsui O.S.K. Lines (MOL) has taken another significant step in its commitment to maritime sustainability by ordering two ammonia dual-fuel bulk carriers. With a deadweight tonnage (dwt) of 210,000 each, the vessels will be built by China’s Qingdao Beihai Shipbuilding and are expected to be delivered between 2027 and 2028.
This development underscores MOL’s dedication to reducing greenhouse gas (GHG) emissions, aligning with global efforts to decarbonize the maritime industry, and exploring alternative fuels such as ammonia to achieve net-zero emissions.
The Potential of Ammonia as a Green Fuel
Ammonia has emerged as a promising alternative fuel for maritime transport due to its zero-carbon properties during combustion. Unlike conventional fossil fuels, ammonia does not emit carbon dioxide (CO2) when used as fuel, making it a critical solution for reducing the carbon footprint of shipping.
MOL’s adoption of ammonia dual-fuel vessels signals a shift in the industry toward innovative solutions for decarbonization. These vessels will reduce emissions during operations and serve as a blueprint for the industry’s transition to greener shipping practices.
By incorporating dual-fuel technology, the vessels will be equipped to run on ammonia while retaining the ability to operate on conventional fuels if necessary. This flexibility ensures that the ships can adapt to varying fuel availability during the transition to a low-carbon future.
Cutting-Edge Vessel Design
Last year, MOL, in collaboration with Mitsui & Co., achieved a significant milestone by receiving Approval in Principle (AiP) from classification society ClassNK for the design of a 210,000 dwt Capesize ammonia-powered bulk carrier.
The vessel design includes advanced features such as two ammonia fuel tanks on deck, which maximize cruising range while optimizing cargo space. This innovative design reflects MOL’s proactive approach to balancing operational efficiency with sustainability goals.
Mitsubishi Shipbuilding was entrusted with the vessel’s design, further solidifying the role of Japanese engineering in driving innovation in maritime sustainability. Additionally, MOL obtained approval for the design of a floating storage and regasification unit (FSRU) for ammonia, showcasing the company’s holistic strategy for integrating ammonia into its fleet and operations.
MOL’s Decarbonization Roadmap
MOL Group’s Environmental Vision 2.1 outlines a comprehensive strategy to achieve its sustainability goals. These include reducing GHG emissions intensity in marine transport by approximately 45% by 2035 (compared to 2019 levels) and achieving net-zero emissions by 2050.
To achieve these ambitious targets, MOL is pursuing five key strategies:
- Enhancing operational efficiency across its fleet.
- Expanding its use of alternative fuels such as ammonia and hydrogen.
- Innovating with next-generation vessel designs.
- Collaborating with industry stakeholders to develop a sustainable fuel supply chain.
- Promoting the adoption of green technologies across its operations.
These strategies highlight MOL’s commitment to leading the industry in sustainable innovation, setting a benchmark for other shipping companies to follow.
Global Collaboration for a Greener Future
MOL’s investment in ammonia dual-fuel vessels is part of a broader trend within the maritime industry to embrace alternative fuels and advanced technologies. Collaboration with stakeholders such as ClassNK, Mitsui & Co., and Mitsubishi Shipbuilding underscores the importance of partnerships in accelerating the transition to sustainability.
The approval and development of ammonia-powered vessels demonstrate the industry’s readiness to explore scalable and practical solutions for decarbonization. As more companies adopt alternative fuels, the infrastructure and supply chains needed to support these technologies will continue to evolve, creating a ripple effect across the sector.
Addressing Challenges in the Adoption of Ammonia
While ammonia offers immense potential as a zero-carbon fuel, its adoption is not without challenges. Key issues include:
- Fuel Supply and Infrastructure: Establishing a reliable and scalable supply chain for ammonia is critical to ensuring widespread adoption. Investments in ammonia production facilities, storage, and bunkering infrastructure will be essential.
- Safety Considerations: Ammonia is toxic and requires specialized handling and storage protocols to ensure the safety of crew and operations. Advanced safety systems and training will play a pivotal role in its adoption.
- Economic Viability: The cost of ammonia as a fuel remains higher than conventional fuels. Scaling production and fostering market demand will be crucial to achieving cost parity.
Despite these challenges, the industry’s proactive efforts, combined with regulatory support and technological advancements, are paving the way for ammonia to become a mainstream fuel option.
