Ammonia-Fueled Vessels Market Growth, Fortescue’s 12-Ship Deal, COSCO’s $780 M Order, and 2 Key Partnerships (2021-2026)
Ammonia Vessel Adoption, Fortescue and COSCO Drive Commercial Scale
The maritime industry’s adoption of ammonia fuel has shifted from conceptual studies and small-scale pilots before 2025 to concrete, large-scale commercial vessel orders in 2026. This acceleration is not driven by technology-push alone but by a demand-pull strategy executed by major cargo owners like Fortescue, who are creating guaranteed offtake for the first generation of ammonia-powered ships, thereby de-risking the entire value chain for shipbuilders, engine manufacturers, and financiers.
Fortescue’s Demand Creation Strategy
The most significant signal of this shift is Fortescue’s landmark agreement in June 2026 to charter up to 12 ammonia-capable Newcastlemax bulk carriers from CMB.TECH. This move directly creates a market for these vessels. Prior to 2025, industry activity was characterized by joint development projects and memorandums of understanding. Fortescue’s action transforms theoretical interest into bankable, long-term charter contracts, providing the financial certainty needed for shipyards to proceed with construction.
COSCO and Höegh’s Fleet Renewal
In response, major shipping lines are committing billions to fleet renewal programs centered on fuel flexibility. In July 2026, COSCO SHIPPING Development approved a $780 million plan for 15 methanol- and ammonia-ready bulkers. This followed a broader October 2025 announcement of a $1.75 billion newbuild program for 29 next-generation vessels. Similarly, Höegh Autoliners placed a definitive order in August 2025 for ammonia-burning engines for its Aurora-class carriers, moving beyond the “ammonia-ready” designation to firm commitments for ammonia propulsion. This contrasts with the 2021-2024 period, which saw orders primarily for LNG dual-fuel ships with ammonia as a distant future option.
$2.5 B+ in Newbuilds, COSCO and Fortescue Lead Investment
Capital allocation in the shipping industry has decisively pivoted toward alternative fuels in 2025-2026, with over $2.5 billion in publicly announced newbuild programs featuring ammonia-capable designs. These investments are a direct reaction to escalating regulatory pressure, such as the EU ETS, and the new market certainty created by charter commitments from major cargo owners. This represents a marked change from the 2021-2024 period, where investment was more cautious and focused on LNG as the primary transitional fuel.
COSCO’s Multi-Billion Dollar Program
The largest single commitment comes from COSCO SHIPPING, which has initiated a fleet overhaul that includes a $1.75 billion investment for 29 next-generation vessels announced in October 2025 and a subsequent $780 million approval in July 2026 for 15 ammonia-ready bulkers. This diversified strategy allows COSCO to hedge against fuel availability risks while positioning its fleet for long-term compliance with decarbonization mandates. The scale of these orders provides a strong demand signal for both shipyards and engine manufacturers.
Fortescue’s Strategic Chartering
While not a direct capital investment in vessels, Fortescue’s agreement to charter up to 12 ammonia-capable bulkers from CMB.TECH is a critical financial enabler. This long-term charter effectively underwrites the newbuild order, removing the primary market risk for the vessel owner and its financiers. This model, where the cargo owner guarantees revenue, is proving essential for funding the first wave of higher-cost, alternatively-fueled vessels and stimulating the market for dual-fuel newbuilds.

Ammonia Engine Readiness, Win GD and Everllence Secure Approvals
Ammonia marine engine technology reached a critical inflection point in 2026, moving from testbed validation to commercial readiness with the successful completion of type and factory approval tests by major manufacturers. This technological de-risking was a prerequisite for the wave of ammonia-capable vessel orders. Before 2025, the viability of large-bore, two-stroke ammonia engines was a significant open question, constraining investment. The milestones achieved in 2026 provided shipowners with the confidence to commit capital to ammonia as a propulsion fuel.
Engine Manufacturer Milestones in 2026
In February 2026, Win GD announced it had completed the world’s first Type Approval Testing (TAT) and Factory Acceptance Testing (FAT) for its ammonia-fueled two-stroke engine. This was followed by the first engine approval for its X 72 DF-A model in June 2026. Concurrently, Everllence (MAN ES) passed the final milestone for its ME-LGIA dual-fuel ammonia engine, which had already secured its first commercial orders from Höegh Autoliners in August 2025. These official certifications from classification societies confirm the technology meets the required standards for safety and reliability for onboard installation.
Performance and Emissions Validation
The testing regimes of 2026 validated that ammonia engines can deliver performance comparable to conventional engines while achieving dramatic emissions reductions. Win GD reported that its engine achieves over 90% GHG reduction when operating in ammonia mode. Other technology developers like Amogy are advancing alternative ammonia-to-power systems based on cracking and fuel cells. This includes work on SOFC in maritime applications, where companies like Shell are exploring solid oxide fuel cells as another pathway for high-efficiency power generation from green fuels.

Strengths and Risks, Fortescue’s Ammonia Demand-Pull Strategy
The demand-pull model for ammonia adoption, led by charterers like Fortescue, creates significant market momentum by providing bankable offtake agreements. This approach effectively solves the “chicken-and-egg” problem between fuel-ready ships and fuel availability. However, it also concentrates risk on the timely development of bunkering infrastructure and the finalization of a supportive global regulatory framework, factors that are largely outside the control of individual companies.
Table: SWOT Analysis for Maritime Ammonia Adoption (2021-2026)
| SWOT Category | 2021 – 2024 (Pre-Commercial) | 2025 – 2026 (Commercial Orders) | What Changed / Validated |
|---|---|---|---|
| Strength | Strong backing from IMO 2050 decarbonization goals and industry consortiums. | Confirmed large-scale vessel orders and charter agreements from major players like Fortescue and COSCO. | The transition moved from theoretical support to tangible, financially committed projects, validating commercial interest. |
| Weakness | Lack of mature, commercially available large-bore ammonia engine technology. | Significant global deficit in ammonia bunkering infrastructure and established safety protocols. | The primary bottleneck shifted from engine technology readiness to shoreside logistics and fuel supply chain maturity. |
| Opportunity | Potential to create first-mover advantage in zero-carbon shipping routes. | Establishment of the first “green corridors” with dedicated ammonia-fueled fleets and bunkering. | The concept of green corridors became an actionable strategy, driven by charterer-led demand for specific trade lanes. |
| Threat | High projected cost of green ammonia compared to conventional fuels, creating economic uncertainty. | Delays and political opposition in finalizing the IMO’s Net-Zero Framework, including carbon pricing. | Regulatory uncertainty became the primary external threat, potentially delaying investment decisions and undermining the business case for early adopters. |
Fortescue’s 2027 Outlook: Green Corridor Execution
The critical variable for 2027 will be the successful establishment of the first green corridors with dedicated ammonia bunkering, which is necessary to validate the operational viability of Fortescue’s chartered fleet and the broader maritime ammonia strategy. With the first dual-fuel vessels set to enter service by the end of 2026, the industry’s focus will pivot entirely from technology demonstration to logistical execution. The performance of these initial deployments will determine the pace of wider adoption.
Bull Case: Infrastructure Keeps Pace
If the development of ammonia bunkering infrastructure and safety protocols in key hubs like Singapore, Rotterdam, and Australian ports keeps pace with vessel deliveries, the industry will see a second wave of firm orders for ammonia dual-fuel ships. Success in these first green corridors would provide a clear, replicable template for other trade routes. A key signal to watch is a definitive and robust carbon pricing mechanism from the IMO’s framework decision in late 2026, which would strengthen the economic case for ammonia over conventional fuels.
Bear Case: Bunkering Bottlenecks Emerge
If ammonia bunkering projects are delayed due to regulatory hurdles, safety concerns, or a lack of investment, the first ammonia-powered vessels could face significant operational constraints. This would damage market confidence and could cause shipowners to pivot newbuild strategies more heavily toward methanol, which currently has a more developed (though still limited) bunkering network. A weak or delayed IMO regulatory framework would exacerbate this trend, as the cost gap between green ammonia and VLSFO would remain a major barrier without a significant carbon price.
