We delivered positive results in 2025 — new contracts, expanded service portfolio, and landmarked e-fuel grade CO₂ purification and liquefaction achievements. The next logical step is investing in knowledge transfer locally for sustainable growth in biomethane and confident operation, said Jaime Casasus-Bribian, CEO of Ammongas.
Following a year of strong operational achievements and international expansion, Ammongas, a Danish leader in biogas upgrading, carbon capture and CO₂ purification and liquefaction, announces the launch of a dedicated technical learning training. The initiative responds to a growing need for deeper technical understanding of amine-based upgrading technology in emerging biomethane markets.
2025: A Year of Milestones and Growth
In 2025, Ammongas successfully commissioned a CO₂ liquefaction plant at Tønder biogas plant with the total capacity of 48,000 tons of CO₂/year delivering best-in-class e-fuels purity CO₂ to Kassø, an e-methanol plant owned by European Energy and Mitsui. This milestone confirms Ammongas’ capability not only in biomethane upgrading but also in integrated carbon capture and carbon management solutions.
The company continued to grow its organization, increasing headcount by 12%, reflecting both market confidence and long-term strategic ambition.
Four major contracts were signed across Norway, the USA and Denmark, two major FEED studies were completed, including Italy’s first carbon capture project from flue gas, pulp and paper in Australia and the company’s first project in Canada — further expanding Ammongas’ international footprint, having more projects to come in 2026.
Ammongas’ service and maintenance portfolio now covers 35 biogas plants in Denmark, Germany, Finland, Norway, the USA and Sweden, having produced a total of 425 million Nm³ of biomethane, which since its establishment in 2002 amounts to close to 80 delivered projects globally, the majority of which were biogas upgrading plants.
Amine technology of upgrading has proven itself through decades of stable operation in Scandinavia. High methane recovery and low operational costs are outcomes of proper design and operation, said Michael Demuth Pedersen, Chief Technical Officer of Ammongas.
From Strong Results to Stronger Partnerships
Outside mature markets, developers and EPC companies often lack direct operational exposure to amine-based upgrading technology. In addition, this technology is a key contributor supporting the strong demand for bio-LNG. While it helps reduce greenhouse emissions, methane emissions related to its production value chain are a key parameter for offtakers.
To bridge this knowledge gap, Ammongas is launching a structured knowledge-sharing initiative in the form of Technical Training in Denmark with a site visit – March 17–18, 2026
(Registration open until March 13 under the link: https://events.teams.microsoft.com/event/cc879663-d0fa-4b39-97ac-1d3d0ed36361@ee6beadb-6064-40ac-a8a9-d6a66d46aef8).
Our over 20 years of experience clearly demonstrates the maturity and reliability of amine upgrading technology. However, technology alone is not enough — local competence is equally important. Through this training, we aim to strengthen long-term partnerships by building real technical understanding, said Oleksandra Gumeniuk, Commercial Manager at Ammongas.
About Ammongas
