LNG – From Waste to Wake in International Shipping News 16/02/2026 The International Maritime Organisation’s (IMO) Net Zero Framework (NZF) adjournment increases the relative importance of the European Union (EU) regulations, including FuelEU maritime and EU Emissions Trading Scheme (ETS). In addition to their own decarbonisation targets shipowners with liquefied natural gas (LNG) engines are financially encouraged to switch to Bio-LNG under EU regulations. The FuelEU Maritime strongly favours Biomethane (specifically Bio-LNG) as a compliance option because of its low to negative life cycle greenhouse gas (GHG) emissions. Biomethane is also a drop in fuel meaning it can be used on LNG fuelled ships without conversion. Ship operators can accrue FuelEU surplus which they are able to bank for future years or sell to operators using fossil fuel under a pooling arrangement. But what is Bio-LNG and Biomethane and how is it produced and delivered? Use of Biomethane Bio-LNG is compatible with existing LNG engines, transfer systems and infrastructure, once it has been upgraded to Biomethane and liquefied. Significant GHG reductions are easy to achieve with minimal retrofitting of LNG vessels. Dual fuel engines can commonly burn LNG or Bio-LNG as well as diesel or biofuels if required. This provides more options should suitable infrastructure not be available in ports. This is known as de-risking. Infrastructure, Bunkering and Storage Bio-LNG is stored in cryogenic tanks at the same temperature as fossil LNG (–162°C) and the same insulated pipes are used for both. Bio-LNG can make use of the growing LNG bunkering network already in place. This includes the following methods of delivery to the ship: • Ship-to-ship transfer • Truck-to-ship • Terminal-based refuelling Production and Liquefaction Bio-LNG can be produced in two ways: Onshore production and liquefaction • Liquefied Biomethane is purified to remove components that would freeze, corrode equipment or degrade LNG quality at cryogenic temperatures prior to liquefaction. It is also filtered after liquefaction to remove debris. • Biomethane is cooled to -162 °C at near atmospheric pressure to turn the gas into a liquid (liquefaction). Integration with existing LNG terminals Shipowners can contract on a “mass balance” basis. This provides creditability, compliance and market functionality. It means that the amount of Bio-LNG delivered to a customer over a certain period cannot exceed the Biomethane produced and liquefied over the same period. This applies when: • Bio-LNG and fossil LNG are physically mixed • Deliveries are done through shared tanks, trucks or terminals • Sustainability certificates are transferred separately The quantity sold as renewable fuel should never exceed the net Biomethane liquefied and available for delivery, after accounting for all process and logistics losses, regardless of physical mixing. Using the same tanks, trucks, terminals and engines for fossil fuels create the following advantages: • Lowers costs • Assists scalability • Makes use of existing LNG hubs Environmental Benefits Biomethane ships offer several significant environmental advantages. Feedstock variables • Waste-derived Biomethane provides the greatest benefits. • Crop-based Biomethane still provides emissions reductions, however there are sustainability restrictions because RED II addresses anything that competes with food production and land use.
