Global bunker fuel market to hit $185b by 2035 on green fuel shift

LNG is the fastest-growing established fuel class.

The global bunker fuel market, valued at $138b in 2026, is expected to climb to $185b by 2035, representing a compound annual growth rate (CAGR) of 3.28%, according to a Market Research Future report. 

Two overlapping policy frameworks, including the International Maritime Organisation's Net-Zero Framework and the European Union's Emissions Trading System, are affecting bunker economics, it said.

Cleaner alternatives such as very-low-sulfur fuel oil, liquefied natural gas (LNG), methanol, and bio-blends are increasingly displacing the high-sulfur residual grades used for decades.

FuelEU Maritime, for instance, requires a 2% reduction in fuel greenhouse-gas intensity from 2025, tightening to 14.5% by 2035.

In 2025, very-low-sulfur fuel oil commanded the largest share of the bunker fuel market, capturing approximately 41.8% of value.

LNG is the fastest-growing established fuel class, expanding at an 11.4% CAGR through 2035. However, barge availability rather than vessel capability has been the binding constraint on LNG uptake at most ports outside Northwest Europe and Singapore.

Marine gasoil captured roughly 18.6% of the market, whilst methanol reached $1.88b.

Bio and synthetic fuels are the fastest-growing fuel category overall, advancing at a 16.8% CAGR. B24 and B30 blends are available in Singapore and Rotterdam but scarce elsewhere, creating an underserved gap for certified blending capability in secondary hubs.

Moreover, international carbon pricing is converting environmental compliance from a cost centre into a commercial product layer.

By bunkering method, ship-to-ship delivery dominates the market, accounting for approximately 52.6%, as it removes berth dependency, letting vessels bunker whilst at anchor or during cargo operations.

In line with this, port-to-ship delivery generated $51.07b, serving pipeline-connected terminal calls where vessels can lift fuel alongside cargo operations.

Further, container vessels command the largest vessel-type share, capturing 31.4% of demand, due to their high utilisation rates and long-haul service patterns.

On a regional basis, Asia Pacific has the biggest market share with 44.6% of global revenue in 2025. Singapore alone represents the largest single-port volume, with sales near 55 million tonnes in 2024.

China captures roughly 26.4% of the regional share through Zhoushan bonded bunker expansion, whilst India contributed approximately 6.1% of the regional share through coastal shipping and Visakhapatnam capacity growth.

Japan holds roughly 8.7% through ammonia and liquefied natural gas technology programmes, and South Korea captures 7.3% through newbuild yard delivery bunkering.
