The Alternative Maritime Fuel Race: Why LNG, Methanol, and Ammonia Are Splitting the Shipping Industry Into Competing Camps
The shipping industry is in the middle of a trillion-dollar fuel gamble, and every shipper with ocean freight exposure has skin in the game. According to DNV's Alternative Fuels Insight platform, alternative-fueled vessels held a 38% share of total gross tonnage ordered in 2025, even as overall newbuilding activity fell sharply from 4,405 vessels to 2,403. The dual-fuel shipping fleet nearly doubled in operational capacity during 2025, according to the World Shipping Council. Yet behind these numbers lies a deepening split: LNG commands 67% of alternative fuel orders, methanol follows at 20%, and ammonia remains a distant but potentially game-changing third option. For shippers, this three-way fuel race isn't an abstract environmental debate — it's the primary driver of ocean freight surcharge structures for the next decade.
The Three-Fuel Race: Proven, Scaling, and Emerging
LNG: The incumbent transitional fuel. Liquefied natural gas currently dominates the alternative maritime fuel landscape. LNG can reduce CO₂ emissions by 20–25% compared to conventional heavy fuel oil, making it the most commercially viable near-term option. CMA CGM has built its decarbonization strategy around LNG, with a target of approximately 200 dual-fuel vessels by 2031 — though that would still cover less than a third of its 650-ship operated fleet. The infrastructure advantage is real: LNG bunkering facilities exist at major ports worldwide, and established supply chains make procurement relatively straightforward.
However, LNG faces a critical vulnerability. Because it's still a fossil fuel, its long-term viability depends entirely on how regulators treat methane slip — the unburned natural gas that escapes during combustion. If the IMO's lifecycle greenhouse gas calculation methodology penalizes methane slip heavily, billions of dollars in LNG-fueled newbuilds could become stranded assets well before they reach their 25-year design lives.
Methanol: The scaling challenger. Maersk placed the industry's defining bet on methanol, now operating 13 dual-fuel methanol-capable ships with another 20 on order from Chinese and South Korean shipyards for delivery starting in 2028. Methanol's appeal lies in its simpler handling requirements compared to LNG — it's a liquid at ambient temperature, meaning vessels don't need the complex cryogenic storage systems that LNG demands. When produced from renewable sources (green methanol), it offers a pathway to near-zero lifecycle emissions.
The bottleneck is supply. Global green methanol production remains a fraction of what the shipping industry would need at scale. Conventional (gray) methanol offers no emissions benefit, meaning the fuel's green credentials depend entirely on scaling bio-methanol and e-methanol production facilities — infrastructure that's still largely in the planning stage.
Ammonia: The long-term wildcard. Ammonia contains no carbon at all, making it theoretically the cleanest option for maritime decarbonization. In March 2025, NYK successfully converted an LNG-powered vessel to run on ammonia fuel, achieving approximately a 95% reduction in greenhouse gas emissions in trials. The Castor Initiative has also advanced plans for very large crude carriers capable of running on ammonia.
But ammonia presents serious practical challenges. It's highly toxic, requiring entirely new safety protocols for bunkering and onboard handling. Engine technology for ammonia combustion at commercial scale is still maturing, and the fuel's energy density is lower than both LNG and methanol, meaning ships need larger fuel tanks for equivalent range.
The Regulatory Pressure Cooker: IMO and FuelEU Maritime
Two overlapping regulatory frameworks are accelerating the fuel transition — and creating confusion about which bet to place.
The IMO Net-Zero Framework, approved at MEPC 83, represents the first-ever global carbon pricing mechanism for international shipping. It includes both a GHG Fuel Intensity standard and an emissions pricing mechanism designed to penalize high-carbon marine fuels. However, as Reuters reported, a key implementation milestone was postponed in late 2025, with detailed lifecycle emissions calculation methodologies and certification standards still being finalized through 2026. The delay has created regulatory uncertainty, but the direction is unmistakable: carbon-intensive marine fuels will cost more, and the price differential will widen every year.
Meanwhile, the FuelEU Maritime Regulation is already in effect for European waters, and the UK's Emissions Trading System will extend to shipping in 2026. These regional mechanisms create immediate financial incentives — or penalties — for carrier fuel choices on EU-linked trade lanes. For shippers moving goods to or through European ports, fuel-choice surcharges are no longer theoretical.
Research from Columbia University's Center on Global Energy Policy highlighted that compliance costs from these mechanisms "tend to diffuse through global supply chains, to cargo owners, port operators, freight forwarders, and ultimately consumers." For small and medium-sized exporters on long-haul, low-margin routes, even modest per-TEU cost increases could carry disproportionate competitive impacts.
Maersk's Methanol Bet vs. CMA CGM's LNG Strategy: Who Wins?
The two largest container carriers have placed fundamentally different bets, and the outcome will shape ocean freight economics for a generation.
Maersk is betting that methanol — particularly green methanol — will become the dominant zero-carbon marine fuel. With 33 methanol-capable vessels in its pipeline, Maersk is building optionality: these ships can burn conventional fuel oil as a fallback while green methanol production scales. The risk is supply: if green methanol remains scarce and expensive, Maersk's fleet premium provides no emissions advantage.
CMA CGM initially built its strategy around LNG but is hedging. The carrier recently deployed methanol dual-fuel vessels on secondary routes, and its broader 200-vessel dual-fuel target combines both LNG and methanol propulsion. CMA CGM's pragmatic approach reflects a conviction that LNG's infrastructure maturity makes it the safer medium-term choice, while keeping methanol options open for tightening regulations.
The market data tells its own story. According to DNV, new orders for alternative-fueled vessels reached 19.8 million gross tonnes in the first half of 2025 alone — exceeding the full 2024 figure by 78%. Despite the overall newbuild market slowdown, Reuters reported that global shipping companies are sticking with green fuel investments even after carbon pricing delays, with Mitsui O.S.K. Lines maintaining its focus on LNG-fueled vessels alongside early-stage ammonia and methanol adoption.
What This Means for Shippers: Surcharges, Contracts, and Carrier Selection
The maritime fuel transition is not a distant industry problem — it's a procurement reality hitting shipper budgets today. Here's what's changing:
Fuel surcharge complexity is exploding. Traditional bunker adjustment factors (BAFs) calculated against a single fuel oil benchmark are giving way to multi-tier surcharge structures that reflect each carrier's fuel mix, regulatory exposure, and green fuel premium. Shippers signing annual ocean contracts in 2026 should expect — and demand — transparency on how fuel-choice costs are allocated.
Carrier fuel strategy should influence procurement decisions. A carrier running LNG on a Europe-Asia lane faces different EU ETS exposure than one burning conventional fuel oil. Shippers can use fuel-strategy alignment as a competitive differentiator when awarding contract volumes, potentially negotiating favorable rates with carriers whose fuel investments align with the shipper's own sustainability commitments.
Green corridor premiums are emerging. As specific trade lanes develop alternative fuel bunkering infrastructure, carriers operating on those corridors can offer verified emissions reductions — at a premium. Shippers with Scope 3 reporting obligations may find these premiums worthwhile for compliance value.
