What AMMONGAS A/S does
Ammongas A/S is a Danish engineering, procurement, and construction (EPC) firm that designs and builds customized environmental plants for biogas upgrading, biomethane polishing for methane liquefaction, CO2 liquefaction, and carbon capture. Founded in 2002 and headquartered in Søborg, Denmark, the company operates more than 40 plants across Northern Europe and 6 plants in the United States, with its proprietary AmgCarbonX CCS and CCUS technology positioned as the differentiator in carbon capture and biogenic CO2 valorization for Power-to-X e-fuel production. The company's product portfolio comprises three interconnected core offerings — biogas upgrading and expansions, biomethane polishing for CH4 liquefaction, and carbon capture with CO2 liquefaction — each delivered as a custom-engineered, turnkey plant covering the full lifecycle from initial design through commissioning.
The firm serves three primary customer segments: agricultural operations converting organic waste into biomethane, renewable energy project developers building biogas and biomethane assets, and Power-to-X facilities requiring biogenic CO2 feedstock for e-fuel synthesis. Revenue is generated through one-time project-based EPC contracts with industrial and developer clients; pricing is not publicly disclosed and is determined by plant specifications, capacity, and site requirements. Marketing is limited to a corporate website and LinkedIn presence, with no consumer-facing campaigns, reflecting a long-cycle consultative sales motion targeting technical stakeholders. In 2022, Ammongas was acquired by European Energy A/S, a Danish global renewable energy project developer, becoming a wholly-owned subsidiary and gaining capital resources and project origination capabilities; the company continues to operate under its own brand identity within the parent's portfolio. A June 2026 agreement to supply a biomethane upgrading system in Llíria, Spain, indicates ongoing geographic expansion beyond the historical Northern European and US markets.

AMMONGAS A/S product offering
Product offeringCore offering
Ammongas A/S designs, engineers, procures, constructs, and commissions customized environmental plants for the renewable energy sector. Its portfolio includes biogas upgrading systems that convert raw biogas into pipeline-quality biomethane, biomethane polishing systems that further purify methane for liquefaction (LNG/LBG), and carbon capture (CCS/CCUS) and CO2 liquefaction systems that capture and utilize biogenic CO2 from biogas processes for industrial use and Power-to-X e-fuel feedstock.
Product overview
Ammongas offers a portfolio of three interconnected core products for biogas and carbon management: (1) Biogas Upgrading & Expansions for converting raw biogas to biomethane, (2) Biomethane Polishing for CH4 Liquefaction to enable liquid renewable fuels, and (3) Carbon Capture & CO2 Liquefaction for capturing and utilizing biogenic CO2. These systems are supported by the company's proprietary AmgCarbonX CCS and CCUS technologies. All solutions are custom-designed and built by Ammongas engineers, covering engineering, procurement, and construction from design to commissioning. The company operates over 40 plants across Northern Europe and six in the United States.

Functional benefit
Products and services
- Biogas Upgrading & Expansions Custom-engineered systems that upgrade raw biogas from agricultural waste and other organic sources to high-quality biomethane by removing CO2, hydrogen sulfide, and water, producing pipeline-quality or vehicle-grade renewable gas for industrial clients and renewable energy developers.
- Biomethane Polishing for CH4 Liquefaction Custom-engineered polishing systems that refine biomethane to ultra-pure methane suitable for liquefaction (LNG/LBG) by removing residual contaminants, enabling long-distance transport and storage of liquefied biomethane as a renewable fuel for industrial buyers.
- Carbon Capture & CO2 Liquefaction Custom-engineered systems that capture and purify biogenic CO2 from biogas upgrading processes and liquefy it for industrial use, transport, or storage, providing feedstock for Power-to-X facilities producing e-fuels.
- AmgCarbonX CCS and CCUS Technologies Proprietary advanced carbon capture, storage, and utilization (CCS/CCUS) technology that captures and purifies biogenic CO2 from biogas upgrading processes, providing critical feedstock for Power-to-X facilities to produce e-fuels and decarbonize hard-to-abate sectors.
Quantifiable outcome
- Supporting Spain's renewable energy goals and reducing emissions through biomethane production from agricultural waste
