Ammongas provides industrial carbon capture and CO2 liquefaction solutions designed to support the recovery, purification, and liquefaction of carbon dioxide. Our technologies help industrial operators transform captured CO2 into liquid CO2 (LCO2), enabling efficient handling, transportation, storage, and potential utilisation across various industrial applications.
By integrating carbon capture with CO2 liquefaction technology, Ammongas supports industrial decarbonisation and the transition towards more resource-efficient energy systems.
Benefits of Industrial LCO2 Plants
Industrial CO2 liquefaction plants can offer several operational and environmental advantages:
Efficient CO2 handling: Liquid CO2 can be stored and transported in suitable pressurised or refrigerated systems.
Carbon utilisation opportunities: Recovered CO2 may be used in industrial processes where the required purity and quality standards are met.
Integration with carbon capture: CO2 liquefaction technology can complement industrial carbon capture systems.
Resource efficiency: Recovering CO2 can create opportunities to utilise a process stream that might otherwise be released into the atmosphere.
Flexible industrial applications: LCO2 can support a range of downstream applications depending on project requirements.
Supporting Industrial Decarbonisation Through Carbon Capture
Carbon capture and CO2 liquefaction technologies contribute to industrial decarbonisation by enabling the recovery and management of carbon dioxide from industrial processes. According to the International Energy Agency (IEA), carbon capture, utilisation and storage technologies can play an important role in reducing emissions from industrial activities. Ammongas develops solutions that support the integration of carbon capture and CO2 liquefaction into industrial operations, with consideration for process requirements, operational efficiency, and downstream CO2 handling.
AmgCarbonX™ Cutting CO₂ Costs
As global momentum builds around climate action, CO₂ taxation is rapidly becoming a regulatory reality. For forward-looking companies, carbon capture is not just an environmental solution – it’s a smart financial strategy to significantly reduce CO₂-related costs.
By integrating carbon capture into your operations, Ammongas enables efficient processing and purification of CO₂ from flue gas or tail gas. With carbon capture now part of our core offering, AmgCarbonX delivers a cost-effective, high-performance path toward lower emissions and a stronger position in a net-zero future. Our high-efficiency system ensures that less than 1% CO₂ remains in the treated flue gas.
With extensive experience in CO₂-separation, Ammongas has built deep expertise in carbon capture from biogas plants-expertise that has since been successfully adapted to flue gas capture. In 2021, Ammongas won the National District Heating Award in collaboration with Thisted and SEG A/S for their demonstration of carbon capture from waste-heat flue gas by using our proprietary technology.
Biogas to Value: Everything You Need, One Partner to Maximize Your Biogas Streams (CH4 & CO2)
Amine-based carbon capture systems providing CO₂ for Power-to-X (e-fuels), food applications (CCU) or sequestration (CCS).
LCO₂
CO₂ liquefaction | LCO₂
Ammongas offers a solution for CO₂ liquefaction. The inlet raw CO₂ entering the liquefaction plant is pre-conditioned and polished prior to compression, dehydration, and condensation before final storage.
Depending on the end-use, the CO₂ can through the Ammongas LCO₂-plant be delivered with a quality of +99% CO₂ for sequestration and up to food-grade or green fuel quality.
We have constructed a CO₂ liquefaction plant at Tønder Biogas, one of the largest biogas plants in Europe. The biogenic CO₂ will be supplied to the nearby Kassø e-methanol plant.
Carbon Capture (CCS & CCUS)
AmgCarbonX
As a natural extension of our expertise in amine-based upgrading for biomethane, we’ve expanded into carbon capture to help shape a low-carbon future with our proprietary technology. By intercepting CO₂ emissions at the source, carbon capture transforms waste into environmental and economic value.
As a driver of circularity, it enables carbon reuse and opens new value streams like carbon credits. It’s a vital tool in the global push for net zero, helping industries meet climate targets without sacrificing performance.
With growing demand for clean technologies, carbon capture is more than a solution – it’s a long-term investment in sustainability, resilience, and innovation.
We’re proud to lead this transition by integrating it into our trusted technology portfolio.
Understanding Carbon Capture Systems
What are Carbon Capture Systems? Carbon capture systems are technologies designed to intercept and isolate carbon dioxide (CO₂) emissions from industrial processes before they can enter the atmosphere, offering a powerful tool in the fight against climate change.
The Process in a Nutshell These systems extract CO₂ from flue gases using specialized methods such as chemical absorption then compress and prepare it for either underground storage or reuse in products like fuels, building materials, or beverages.
Why It’s a Game Changer Carbon capture offers a practical solution for hard-to-abate sectors such as cement production and waste incineration, helping reduce emissions without disrupting essential operations.
Real-World Applications Carbon capture is already being used in biogas upgrading facilities, and heavy industries to cut emissions, support compliance with environmental regulations, and unlock new value from captured CO₂.
Looking Ahead While costs and infrastructure remain challenges, advances in technology and growing global investment are rapidly turning carbon capture from a niche solution into a central pillar of climate strategy.
Cases
Documenting Efficient Carbon Capture at Ammongas
Carbon capture is an important measure in the battle against climate change. Ammongas has received key documentation confirming the quality of their carbon capture system for waste-to-energy (WtE) plants.
After collaborating with FORCE Technology, Ammongas now has documentation to show that their system not only efficiently captures CO2, but also that it does not release problematic substances like nitrosamines and nitramines at concentrations that would be cause for concern.
“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.”
