DUNKIRK, FRANCE – July 2025 — Dunkerque LNG has successfully carried out its first Bio-LNG loading operation, marking a significant milestone in the decarbonization of heavy transport sectors. The operation, completed in June 2025, involved the loading of Bio-LNG onto a Molgas Energy Group tanker at the Dunkirk LNG terminal.
This development reflects growing momentum in the European energy sector toward sustainable and renewable energy solutions, particularly in the areas of maritime and road transport.

Bio-LNG: A Renewable Alternative
Bio-LNG, or liquefied biomethane, is a renewable gas produced from organic waste such as agricultural by-products, industrial residues, and household waste. Once purified, biomethane is injected into the natural gas grid and can then be liquefied to form Bio-LNG, offering a cleaner alternative to conventional fossil fuels.
As of March 31, 2025, more than 750 biomethane production facilities in France were injecting renewable gas into the national grid. These facilities collectively have a capacity of 14.3 terawatt hours (TWh) per year, representing a 2 percent increase compared to the end of 2024. The expansion of this infrastructure supports France’s and the EU’s goals to reduce greenhouse gas emissions in hard-to-abate sectors.
Liquefaction by Equivalence
The recent loading operation was made possible through the application of a regulatory mechanism known as “liquefaction by equivalence.” Introduced under European Regulation 2022/996, this approach allows European LNG terminals to certify LNG as Bio-LNG, provided that an equivalent quantity of biomethane has been injected into the European gas grid.
This method enables the use of existing infrastructure without physical constraints on volume. It also simplifies the logistics of producing and distributing Bio-LNG while ensuring that the environmental benefits are preserved and verifiable.
Certified Under ISCC Standards
The liquefaction and certification process is governed by the International Sustainability and Carbon Certification (ISCC) system. This certification guarantees compliance with sustainability criteria, requiring regular audits and transparent accounting of greenhouse gas emissions.
In April 2025, Dunkerque LNG obtained ISCC certification, enabling the terminal to offer Bio-LNG services that are traceable and verifiably sustainable. A Proof of Sustainability (PoS) accompanies each Bio-LNG batch, ensuring that the biomethane’s origin, injection, and conversion are fully documented.
A Joint Step Toward Decarbonization
The successful Bio-LNG shipment was conducted in partnership with Molgas Energy Group, a leading European distributor of LNG, Bio-LNG, and renewable gases. With a presence in over 16 countries, Molgas supplies low-carbon fuels to the industrial, transport, and marine sectors. The company operates a wide network of liquefaction terminals, fuel trucks, regasification plants, bunkering vessels, and refueling stations.
“This first Bio-LNG loading at Dunkerque LNG represents a significant step forward in offering practical, scalable solutions for the decarbonization of transport across Europe,” a Molgas spokesperson said.
The operation demonstrates how existing LNG infrastructure can be adapted for renewable fuel distribution, offering both environmental and economic benefits for the energy transition.
Bio-LNG Services Available
Dunkerque LNG has now opened its Bio-LNG service to customers by reservation. The offering is part of the terminal’s broader strategy to support energy diversification and emissions reduction in line with national and EU targets.
Regulatory Compliance and Certification
Bio-LNG certificates issued through this process are compliant with several major regulatory frameworks, including:
- FuelEU Maritime
- International Maritime Organization (IMO)
- EU Emissions Trading System (ETS 1 & 2)
- IRICC (Industrial Renewable Investment Climate Certificate)
About Molgas Energy Group
Molgas Energy Group is a leading supplier and distributor of LNG, Bio-LNG, and renewable gases across Europe.

About Dunkerque LNG
The Dunkirk LNG terminal was developed to meet growing demand for imported natural gas in Europe, particularly in response to declining North Sea production and shifting geopolitical supply routes. LNG transport offers flexibility and cost-efficiency over long distances and supports secure energy delivery where pipeline access is limited.
Dunkerque LNG is owned and operated by Dunkerque LNG SAS, with shareholders including:
- A consortium comprising Fluxys, AXA Investment Managers – Real Assets (on behalf of its clients), and Crédit Agricole Assurances (61%)
- A consortium of Korean investors led by IPM Group and Samsung Asset Management (39%)
