Ammongas 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 Kassø facility 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.
A significant portion of the captured CO₂ will be delivered to European Energy’s Kassø e-methanol facility, where it will be a crucial component in producing e-methanol — a sustainable fuel and chemical essential for decarbonising industry and transportation. 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).
“Baltic countries have enormous potential for applying such technologies, given the high level of expertise and experience in the existing biogas sector, as well as the rapidly developing biomethane industry. Around 40% of biogas consists of bio-CO₂, which can become an additional source of revenue for biomethane plant owners. The amine-based biogas upgrading technology used by Ammongas for over 20 years has already earned a strong reputation for high efficiency in Scandinavian countries, where more than 50% of all biomethane is supplied from Ammongas installations,” – Oleksandra Gumeniuk, Commercial Manager of Ammongas in Eastern Europe.
