Enhancing Biogas Upgrading Systems: CO₂ Recovery for High-Purity Food-Grade CO₂
Anaerobic digesters generate biogas, a mixture primarily composed of methane (CH₄) and carbon dioxide (CO2), along with trace amounts of other gases. While raw biogas has great potential, it needs to be purified to increase its methane content. This process of biogas CO2 removal is critical for transforming raw biogas into valuable products like grid-ready biomethane and food-grade CO₂.
Why is Biogas CO2 removal Essential?
Upgrading biogas is crucial for turning waste into renewable energy. Here’s why:
Reducing Greenhouse Gas Emissions: By capturing and utilizing both methane and carbon dioxide, we prevent their release into the atmosphere. This is particularly important for helping your company meet its zero-emission targets and contribute to global climate action.
Maximizing Profitability: Biogas upgrading systems can generate multiple revenue streams by selling both biomethane and CO2. This dual-output approach reduces operational costs and increases profitability, making biogas CO2 removal a smart investment for local businesses.
Renewable Energy Source: Upgraded biogas replaces fossil fuels, providing a clean, renewable energy source that can be used for heating, electricity, and even vehicle fuel. This makes biogas a versatile option for the growing renewable energy sector.
With mature technologies available, biogas CO2 removal can be done efficiently, with no harmful emissions, making it a key component in the shift to a sustainable energy future.

How Biogas is Upgraded
Raw biogas, produced through anaerobic digestion, is a valuable energy source, but it requires purification before it can be used efficiently. The process of biogas upgrading removes impurities and increases the methane (CH₄) concentration, turning it into biomethane or renewable natural gas (RNG). This upgraded gas can be injected into the natural gas grid or used as a clean fuel for vehicles.
In its raw form, biogas consists of methane (CH₄), carbon dioxide (CO₂), and smaller amounts of hydrogen sulfide (H₂S), water vapor, and trace gases. While methane is the key energy component, the presence of CO₂ and impurities lowers its calorific value and limits its usability. Biogas upgrading eliminates these unwanted components, making the gas more efficient and compliant with grid standards.
The Biogas Upgrading Process:
- Biogas Collection: Raw biogas is captured from anaerobic digesters processing organic waste such as agricultural residues, food waste, and manure.
- Pre-Treatment: Impurities like hydrogen sulfide and moisture are removed to prevent equipment corrosion and optimize the upgrading process.
- CO₂ Separation: Using advanced separation techniques such as membrane filtration, water scrubbing, pressure swing adsorption (PSA), or amine scrubbing, CO₂ is extracted, increasing the methane content.
- Gas Drying & Final Purification: Remaining contaminants, including volatile organic compounds (VOCs), are removed to meet gas grid specifications or vehicle fuel standards.
- Grid Injection or Storage: The purified biomethane is either injected into the natural gas grid or compressed for storage and transport as a renewable fuel.
Integrating Carbon Capture into Biogas Upgrading
In traditional biogas upgrading, step 3 involves separating carbon dioxide (CO₂) from methane (CH₄) to increase the methane concentration. Our carbon capture technology enhances this process by introducing an additional flow that efficiently captures and repurposes the CO₂ instead of releasing it into the atmosphere, eliminating emissions and making the process carbon negative.
Patented Carbon Capture for CO2 Liquefaction
Our patented carbon capture technology is key to our CO2 removal and liquefaction process. After the biogas is upgraded, the captured CO2 is condensed into liquid form, ready for reuse in various industries throughout Cologne and beyond. This process is energy-efficient and highly customizable, tailored to different inlet compositions and project scales in the region.
Key Advantages of Our Technology:
Zero Methane Slip: Our patented CO₂ liquefaction technology ensures zero methane slip, a requirement for biogas upgrading installations aiming to meet strict environmental standards and maximize sustainability.
Food-Grade CO₂: Our process produces high-purity liquid CO₂ suitable for food processing, greenhouses, and other industries. With the addition of an analysis unit, high-quality standards are guaranteed.
Energy Efficiency: By optimizing the liquefaction process, we ensure minimal energy consumption, which reduces operational costs for our customers.
Biogas Membrane Separation Technology
The biogas membrane separation system is designed to efficiently separate CH₄ from CO₂, maximizing methane yield and minimizing methane slip. This technology is known for its simplicity, reliability, and operational efficiency, making it ideal for use in biogas upgrading projects.
Key Benefits of Membrane Technology:
High Efficiency Methane Separation: A membrane system ensures the production of high-purity biomethane with minimal methane losses, perfect for biogas plants.
Flexible Design: The membrane configuration can be customized to match the biogas composition and required output, ensuring optimal performance for each application.
