UABIO member Ammongas has delivered the first liquefied bio-CO₂ to an e-methanol plant in Denmark
On March 17, 2025, Ammongas, a member of the Bioenergy Association of Ukraine, has delivering its first truckload of biogenic CO₂ from Tønder Biogas. The CO₂ will be used for European Energy’s Power-to-X facility in Kassø, where it will play a key role in the production of e-methanol.
Ammongas, is developing carbon capture (CCU and CCS) technology in southern Denmark via a new CO₂ liquefaction facility at Tønder Biogas — one of the largest biogas plants in Europe. This facility, which is now commissioned, will capture, purify, and liquefy biogenic CO₂. The plant has the capacity to produce 48,000 tonnes of liquefied CO₂ annually for European Energy’s renewable energy projects.
The liquefaction unit has been engineered, constructed, and commissioned by Ammongas, a subsidiary of European Energy specialising in CO₂ liquefaction. Ammongas’ technology pre-conditions and polishes raw CO₂ before compression, dehydration, and condensation, ensuring a purity level exceeding 99%. This high-purity CO₂ is highly versatile and suitable for sequestration, food-grade applications, or green fuel production.
“The first delivery of biogenic CO₂ from Tønder Biogas to our Kassø facility is a major step towards scaling green fuel production in Denmark. By integrating carbon capture with Power-to-X, we are closing the carbon loop and paving the way for a more sustainable energy future”, says Jaime Casasus-Bribian, CEO of Ammongas.
By capturing and repurposing biogenic CO₂, the project supports emissions reduction and promotes circularity in renewable energy production. In addition, it serves as a prime example of Carbon Capture and Utilisation (CCU).
“Ukraine has a huge potential for the application of such technologies, given the high level of competence and experience already in the existing biogas sector. In addition, a new and rapidly developing area of biomethane has emerged. About 40% of biogas is released as bioCO2, which can be an additional source of income for biomethane plant owners. Ammonia technology for biogas upgrading, which has been used by Ammongas for 20 years, has already proven to be highly efficient in the Scandinavian countries. More than 50% of all biomethane is supplied from Ammongas installations there”, says Olexandra Gumeniuk, Commercial Manager for Ammongas Eastern Europe.
