A wave of fresh data and project moves is tightening the case for alternative fuels at sea. Singapore’s Global Centre for Maritime Decarbonisation (GCMD) released six-month findings showing continuous B24 use performed on par with VLSFO, addressing durability and engine-wear concerns that slowed broader adoption. At the same time, methanol infrastructure is stepping up, from India’s first green-methanol bunkering project to commercial e-methanol output in Denmark, while ammonia advances span “ammonia-ready” boxship orders, new safety systems, and engine performance gains. Together, these signals translate into clearer fuel options, firmer capex decisions, and a more bankable decarb runway for owners.

Bottom-Line Effect
Biofuels pass the endurance test
GCMD’s Project LOTUS shows six months of continuous B24 use matched VLSFO on performance with no adverse engine/fuel-system impact; 185 lab samples and onboard inspections back the finding. Owners and charterers get operational evidence, not just pilots. Sources: GCMD, trade press
Drop-in fuel leverages existing tanks/lines; lowers switching friction; easier to scale on current voyages.
📈 Faster uptake where supply exists; 📉 lower perceived tech risk; potential opex neutrality vs VLSFO.
India lights up methanol bunkering
Foundation laid for a 750 m³ green-methanol bunkering & refuelling facility at VOC Port (Tuticorin), India’s first of its kind. Early ecosystem: bunker barge build-out and policy support flagged in parallel reports.
Adds a new supply point on key East-West lanes; de-risks South Asia methanol routes; supports dual-fuel fleet deployment.
📈 Regional bunkering revenue; 📉 less deviation for methanol-capable ships; improved route optionality.
Commercial e-methanol goes live
Denmark’s Kassø facility (European Energy + Mitsui) begins commercial e-methanol production (~42,000 t/y), with Maersk among offtakers; excess heat feeds district heating.
Bankable offtake enables long-term fuel contracts; anchors Northern Europe green corridors for dual-fuel fleets.
📈 Supply visibility for early movers; 📉 green premium persists but hedged by LT deals.
Methanol pipeline swells
Global project pipeline for renewable/low-carbon methanol climbs to ~46.3 Mt by 2030 across e-methanol and bio-methanol projects tracked this year.
📈 Reduces fuel security risk for dual-fuel orders; 📉 narrows long-term cost gap as scale builds.
Ammonia moves from paper to steel
DNV notes rising ammonia-fuel momentum; new orders include Yang Ming’s ammonia-ready boxships (Hanwha Ocean). AEA’s latest LEAD dataset tracks hundreds of ammonia-ready or ammonia-fuelled vessels across segments.
Designs future-proofed for fuel switch; resale values aided by “ready” notation; aligns with 2030s adoption curve.
📈 Asset longevity & charter appeal improve; 📉 near-term capex uplift for readiness features.
Safety toolkits get approvals
HD Hyundai’s ammonia-fuel safety solution secures class approval (KR), pointing to maturing risk controls around toxic fuel handling.
Supports flag/port acceptance; shortens approval timelines for first ships and retrofits.
📈 Greater bankability for ammonia projects; 📉 compliance/engineering costs front-loaded.
Engines hit emissions targets
Wärtsilä reports up to ~90% GHG reduction at 95% ammonia energy share on its four-stroke platform; commercial two-stroke ammonia tech rolls out via OEM programs and pilots.
Improving tank-to-wake results help compliance math (EU ETS/FuelEU); pilots pave way for fleet specs.
📈 Compliance cost relief potential; 📉 fuel/NOx/N₂O handling still drives system capex.
Asia bunkering keeps scaling
Shanghai’s ship-to-ship methanol bunkering is operational; Singapore has executed bio-methanol bunkering for dual-fuel feeders and targets >1 Mt/y methanol supply by 2030. COSCO completed domestic green-methanol bunkering on a newbuild.
Network effects: more supply points reduce deviation and charter risk for methanol fleets.
📈 Route flexibility and uptime improve; 📉 green premium moderated as volumes rise.

📈 Winners
📉 Losers
Biofuel producers and blenders: validated B24 endurance lifts demand at hubs with supply and quality assurance.
Methanol-capable fleets: expanding bunkering points and first e-methanol volumes improve charter appeal and route flexibility.
Ports adding green bunkers: methanol and bio-methanol facilities capture marine fuel margin and incremental calls.
Engine and systems OEMs: class approvals and performance milestones convert trials into purchase orders.
Owners with “ready” notations: ammonia-ready or methanol-ready designs support residual values and eligibility in tenders.
Green corridor financiers: bankable offtake and infrastructure plans de-risk project cash flows and linked charters.
High-intensity legacy tonnage: rising ETS and FuelEU costs erode TCEs without drop-in or dual-fuel options.
Ports without alt-fuel capability: risk of call diversion as green corridors shape scheduling and contracts.
Single-fuel bunker suppliers: VLSFO-only portfolios face volume leakage to blended and methanol products.
Late movers on safety and training: ammonia and methanol handling requirements add rush costs and delays.
Cargo owners with weak emissions data: tighter reporting and well-to-wake claims narrow procurement choices.
Short-term charterers on non-compliant ships: fewer eligible vessels push hire up and limit itinerary options.
Context reflects recent GCMD findings, OEM updates, class approvals, and port bunkering announcements.
Biofuels now have credible “run-it-for-months” data behind them, making B-blends the near-term compliance and carbon-cut tool that doesn’t require a new ship. Methanol is moving from ship orders to supply reality as bunkering nodes spread and first commercial e-methanol volumes ship, while ammonia is laying the foundations, ready notations, safety kits, and engine milestones, for broader uptake later in the decade. For owners, the financial signal is clearer: biofuels ease today’s carbon and compliance burden using existing hardware; methanol-capable assets gain routing and fuel-security comfort as infrastructure scales; ammonia’s capex is earlier and heavier but increasingly de-risked by standards and technology progress. The transition won’t be price-neutral, but the pathways are converging from “pilot” to “plan.”
