48 Ports Against 800+ Vessels: The Alternative Fuel Infrastructure Gap Reshaping Maritime Procurement

"Demand for bio-LNG in maritime transport far exceeds current production, revealing a significant supply gap." This supply-demand imbalance is reshaping procurement strategies across the sector, making fuel allocation timing a strategic asset.

The Order-to-Infrastructure Chasm

The disparity between vessel orders and bunkering capacity is stark. As of early 2025, the global alternative-fuel-capable orderbook stands at 1,942 merchant vessels: 1,259 ordered for LNG, 385 for methanol, 139 for LPG, and smaller numbers for hydrogen, ammonia, and biofuels. Yet in 2024, only 191 ports worldwide had active LNG bunkering facilities—a ratio of approximately one operational port for every eight to ten ordered vessels. An additional 81 ports were under construction, yet even their completion will barely narrow the logistics bottleneck. LNG bunkering vessels themselves number just 64 in operation with only 16 additional units on order through 2028, perpetuating what DNV Maritime describes as "a significant gap between LNG bunkering supply and demand."

This infrastructure lag extends beyond pure capacity. For methanol, the situation is even more acute: fewer than 10 ports currently offer commercial-scale methanol bunkering. Singapore's move to issue methanol bunkering licences from 1 January 2026—selecting Global Energy Trading, Golden Island, and PetroChina International as licensed suppliers—marks a watershed moment in Asia-Pacific procurement. Yet even Singapore's new capability will serve as a regional hub rather than a network-wide solution. The constraint is not technological but logistical: building bunkering infrastructure requires years of permitting, capital expenditure, and regulatory coordination.

Singapore's Green Methanol Play: Early-Mover Advantage in Motion

Singapore's first commercial green methanol bunkering facility opened at Tuas Port on 20 March 2026, following six months of trials. The facility builds on May 2024 milestones when X-Press Feeders successfully completed the first simultaneous methanol bunkering and cargo operations (SIMOPS), refuelling a container vessel with 300 metric tonnes of bio-methanol from Global Energy Trading using mass flow metering technology. Singapore's Maritime and Port Authority (MPA) has subsequently mandated training under the Maritime Energy Training Facility, with crew certifications now required for methanol handling—a regulatory framework that competitors have yet to establish at comparable scale.

For procurement teams, Singapore's lead translates directly into access. Golden Island's bunker tanker, the Golden Antares, discharged 5,000 metric tonnes of ISCC EU-certified green methanol to Stolthaven Terminal Singapore in August 2025. The methanol originated from Tianjin and was sourced from Towngas (Hong Kong and China Gas Company), which holds both ISCC EU and ISCC PLUS sustainability certifications. Green methanol's carbon intensity savings of 75% versus very low sulphur fuel oil (VLSFO) are now quantifiable and auditable at point of delivery—a critical advantage for operators seeking to meet FuelEU Maritime compliance thresholds.

Rotterdam's Expansion: Scale Meets Regulatory Momentum

Rotterdam's trajectory illustrates a different infrastructure model. The Gate terminal, a joint venture between Gasunie and Vopak operational since 2011, is expanding from 12 billion cubic metres (bcm) import and re-export capacity to 16 bcm, with a fourth LNG storage tank (180,000 cubic metres) and an additional 4 bcm regasification capacity expected online in H2 2026. In March 2024, Gate achieved first bio-LNG production, with a liquefier capacity of approximately 100,000 tonnes per year. Bio-LNG volumes through Rotterdam surged sixfold in 2025 to 17,644 cubic metres, versus 2,775 cubic metres in 2024. Biomethanol bunkering also tripled, from 3,946 tonnes in 2024 to 11,819 tonnes in 2025, driven by FuelEU Maritime regulations that reward blending and penalise vessels not meeting carbon intensity benchmarks.

Gate's expansion strategy reflects long-term European demand signalling. Uniper became the first shipper at Rotterdam's hub to offer liquefied biomethane in 2024, with biomethane sourced through the Dutch natural gas grid and liquefied at Gate's existing infrastructure. Peninsula expanded its Rotterdam footprint with a new biofuel storage and blending facility (30,000 cubic metres capacity, expandable to 110,000 cubic metres by January 2026), featuring nine tanks dedicated to blending operations. This federated infrastructure model—multiple operators, shared grid access, ISCC EU certification—is locking in European supply chains and setting procurement norms.

The Supply Bottleneck: Bio-LNG Production Versus Fleet Demand

Production capacity remains the underlying constraint. SEA-LNG's 2023 market analysis reported that annual biomethane production was approximately 30 million tonnes—equivalent to only 10% of global shipping's total annual energy demand. Yet only 5% of potential biogas and biomethane production is currently being utilised. Rystad Energy's analysis confirms that unrestricted biodiesel demand would exceed total supply, and bio-LNG outlook is "equally restricted, in both allocation and production capacity." This supply gap translates into scarcity pricing: low-carbon methanol premium to conventional methanol can vary between €100 and €300 per tonne depending on certification status and geography. Early procurement locks in supply before cost escalation occurs.

Bio-LNG's supply story differs by region. Fluxys reported a 73% increase in bio-LNG demand at its Zeebrugge terminal, with maritime transport a key growth driver. Gasum extended its bio-LNG supply agreement with Nordic ferry operator Wasaline through 2027, supporting a carbon-neutral shipping corridor across the Baltic Sea. However, these regional pockets mask a global scarcity: Rystad Energy identifies the capacity to produce biofuels as "not keeping up" with demand, and bunkering operations remain concentrated in Europe (Rotterdam, Antwerp, Zeebrugge, Hamburg) and Asia (Singapore). The implication is stark for procurement teams: securing long-term supply contracts now at current price points will require negotiating with a handful of certified producers and terminals.

The Regulatory Ratchet and Cost Escalation Risk

FuelEU Maritime regulations, which expanded in January 2026 to include methane and nitrous oxide on CO₂-equivalent basis, create binding incentives for blending. Shipping companies must monitor emissions and purchase allowances, with compliance obligations rising from 40% of emissions coverage in 2025 to full coverage by 2027. EU Emissions Trading System (ETS) extension now covers 100% of intra-EU emissions and 50% for voyages to/from the EU, increasing operating expenses for shipping lines operating European routes. These regulations do not distinguish between mass-balanced and off-grid biomethane, meaning certified low-carbon alternatives command regulatory premiums.

For procurement buyers, this regulatory environment creates a cost squeeze: as compliance deadlines tighten, late-stage fuel buyers will face supply rationing and cost escalation. Early negotiators securing ISCC-certified bio-LNG or green methanol allocations avoid margin compression. Lloyd's List and Lloyd's Register found that 70% of surveyed respondents identified "uncertainty regarding future decisions on fuel, regulations, port infrastructure, and available solutions" as obstacles to decarbonisation. This uncertainty directly impacts supplier negotiations: operators with secured allocations gain leverage in pricing discussions with fuel suppliers.

What This Means for Procurement Teams

The infrastructure gap creates a window of strategic opportunity that is rapidly narrowing. Shipowners and fuel procurement teams should pursue direct supply agreements with ISCC-certified producers—Towngas in Asia, OCI Global (methanol), Proman, and European biomethane aggregators. Second, participate early in port infrastructure governance: Singapore's licensing process and Rotterdam's expansion projects are open to supplier input; early engagement shapes allocation and pricing. Third, diversify bunkering ports along your trading lanes: reliance on a single hub (Singapore for Asia-Pacific, Rotterdam for Europe) replicates the supply risk that regulations are meant to mitigate. Finally, lock in forward contracts for certified fuel allocations now, before cost escalation becomes unavoidable and availability tightens further into 2027. The vessels are on order. The ports are still under construction. The fuel supply gap is real. Those who move first secure the advantage.
