Biomethane and the Race to Decarbonise Global Shipping
Biomethane is doing something most alternative fuels are still only promising: it is powering real ships on real routes right now. While the debate around hydrogen, ammonia, and e-fuels continues to evolve, liquefied biomethane has moved from pilot stage to commercial reality. The industry has settled the question of whether it works. The focus now is on how fast the sector can scale it.
What Makes Biomethane Different?
Biomethane, also known as liquefied biomethane (LBM) or bio-LNG, comes from upgrading biogas produced through the anaerobic digestion of organic materials such as agricultural waste, food waste, and manure. It sets itself apart from competing fuels on four counts:
- It is chemically identical to fossil LNG. Vessels on LNG can switch to bio-LNG without changing engines or bunkering systems.
- It is a genuine drop-in fuel. No infrastructure rebuilds. No vessel redesigns.
- It is renewable and certifiable. Under ISCC EU, producers verify sustainability credentials through a documented chain of custody.
- It is available today. Bunkering operations are active across Belgium, France, Finland, the Netherlands, Norway, Spain, Sweden, and the UK.
In an industry where retrofitting costs and downtime carry significant weight, that compatibility is not just a convenience. It is a strategic edge.
The Regulatory Clock Is Running
Three major policy frameworks are reshaping shipping economics right now:
EU Emissions Trading System (EU ETS): Full compliance takes effect in 2026. Every tonne of CO? from vessels at European ports carries a direct financial cost.
FuelEU Maritime: In force since January 2025, this regulation requires a stepwise reduction in the greenhouse gas intensity of energy on European voyages. Benchmarks tighten through 2050.
IMO Net-Zero Framework (MEPC 83, April 2025): The IMO introduced a tiered penalty system globally. Vessels exceeding emissions caps face levies of $100 to $380 per tonne of CO?. The framework targets net-zero shipping emissions around 2050, with 5 to 10% of energy from near-zero GHG fuels required by 2030.
These obligations already shape fleet investment, bunker strategies, and port planning. Among available options, sustainable marine fuels based on biomethane offer one of the fastest and most cost-competitive compliance routes today.
The Numbers Behind the Momentum
2025 was a breakout year for LBM in shipping. According to SEA-LNG's January 2026 annual report:
- LBM bunkering reached record volumes, with at least seven major bunker suppliers active across European ports.
- The LNG fleet that bio-LNG serves grew to 1,369 dual-fuel vessels in operation and on order.
- LNG bunkering is available in 222 ports globally, up from a single bunkering vessel in 2016.
- LBM now reaches cruise ships, container lines, ferries, tankers, car carriers, bulkers, and offshore supply vessels.
A key milestone came through the Rotterdam-Singapore Green Corridor pilot, where Shell supplied 100 tonnes of ISCC EU-certified LBM to a CMA CGM container vessel. Price agencies S&P Global and Argus now publish dedicated LBM bunker price assessments, a clear sign of a market reaching maturity.
Supply: The Bottleneck and the Opportunity
The core challenge is production scale. The IEA estimates organic waste streams alone could yield around 1 trillion cubic metres of biomethane annually, roughly 25% of current global natural gas demand. Yet producers tap only about 5% of that potential today, even as output grows at 20% per year.
Lloyd's Register projects bio-methane could account for 34% of the global marine fuel mix by 2050, but notes that current supply falls well short of that demand scenario. Closing the gap requires:
- Investment in biogas upgrading and liquefaction infrastructure
- Long-term supply agreements that give producers confidence to build capacity
- Policy incentives for waste-based feedstock development
Producers, off-takers, and infrastructure investors who move early will hold a clear advantage as compliance costs rise.
Where Biomethane Fits in the Bigger Picture
Biomethane is not the only fuel the industry needs. Long-term decarbonisation will draw on a portfolio of sustainable fuels: green ammonia, e-methanol, hydrogen-based e-fuels, and advanced biofuels each serve different vessel types and timelines.
What biomethane uniquely offers is the ability to act now. LNG dual-fuel vessels represent 10% of global deadweight tonnage. Operators can use the same engines, the same tanks, and the same bunkering infrastructure today while delivering lower lifecycle emissions. As e-methane scales in later years, those assets carry forward along the decarbonisation curve without becoming stranded. That is not a compromise. That is a strategy.
Be Part of the Conversation in Amsterdam
Shifting to sustainable marine fuels takes alignment across shipowners, fuel producers, port operators, financiers, and policymakers. Leadvent Group's World Sustainable Marine Fuels Forum is built to drive exactly that.
The forum takes place on 27–28 May 2026 at the Radisson Blu Hotel Amsterdam Airport, Amsterdam, Netherlands, and is available to attend both in person and virtually as a hybrid event.
The forum brings together 150+ industry professionals, 35+ expert speakers, and organisations including Wärtsilä, Lloyd's Register, Eni Trade & Biofuels, Bureau Veritas, ING Bank, Siemens Energy, Wood Mackenzie, Fortescue Energy, the European Investment Bank, and the European Biogas Association. Leadvent Group is one of Europe's leading B2B conference organisers, with a strong record of convening senior decision-makers across the energy transition. The Sustainable Marine Fuel Forum is where maritime energy's roadmap gets built.
If you work in shipping, fuel supply, ports, finance, or policy, this is the forum to be at.

Frequently Asked Questions (FAQs)
1. Is biomethane truly carbon-neutral as a marine fuel?
It depends on the feedstock. Bio-LNG from agricultural residues and manure can achieve very low, and sometimes carbon-negative, lifecycle emissions by capturing methane that would otherwise enter the atmosphere. Under ISCC EU certification, producers must verify sustainability credentials for every bunkering transaction.
2. Can existing LNG-powered vessels use biomethane without modifications?
Yes. Liquefied biomethane is chemically identical to fossil LNG. Ships with LNG dual-fuel engines can switch to LBM without engine changes or infrastructure modifications, making it the most accessible clean fuel option for the LNG fleet today.
3. How does biomethane compare in cost to other alternative marine fuels?
LBM carries a premium over fossil LNG, approximately 169% higher according to the World Shipping Council's 2025 EU Fuel Report. However, it is considerably more cost-competitive than green ammonia or e-methanol, especially when operators account for compliance savings under EU ETS and FuelEU Maritime.
4. What long-term role will biomethane play in the shift to net-zero?
Biomethane is a high-impact bridge fuel that delivers real emissions reductions using existing infrastructure. Lloyd's Register projects it could represent around a third of the global marine fuel mix by 2050. Its long-term share depends on how aggressively the industry scales production. Investment in biomethane today builds the same infrastructure that will support e-methane tomorrow.
