Biogas-CCS Carbon Removal

Date: January 20, 2026

Biogas with carbon capture and storage (Biogas-CCS)

As companies accelerate their climate strategies, there is growing demand for carbon removal solutions that can be deployed using existing infrastructure and deliver durable results.

One such solution is Biogas with Carbon Capture and Storage, often referred to as Biogas-CCS.

Biogas-CCS captures and permanently stores biogenic CO₂ released during biogas production. By combining anaerobic digestion with carbon capture and geological storage, it delivers durable carbon removal using assets that already operate today.

What is Biogas-CCS

Biogas-CCS is a carbon dioxide removal method applied to biogas production facilities.

Biogas is produced when organic materials such as agricultural residues, manure, and organic waste are broken down through anaerobic digestion. During this process, a biogenic CO₂ stream is generated alongside methane.

When the biogenic CO₂ is captured and permanently stored underground, the overall effect is negative emissions. For this reason, Biogas-CCS is classified as carbon dioxide removal (CDR).

How Biogas-CCS works

The result is durable carbon removal: CO₂ that was originally absorbed from the atmosphere is permanently stored underground.

Why invest in Biogas-CCS

• Immediate deployment: Builds on existing biogas facilities and mature processes.
• Durable removal: CO₂ is permanently stored in geological formations.
• High-purity CO₂ streams: Biogas upgrading produces concentrated CO₂, simplifying capture.
• Infrastructure leverage: Uses assets that already produce energy and manage waste.

Climate impact

The climate impact of Biogas-CCS comes from the permanent storage of biogenic CO₂ that would otherwise be released to the atmosphere.

Net carbon removal depends on the volume of CO₂ captured and stored, minus emissions associated with feedstock handling, plant operations, transport, and storage.

Because the CO₂ is stored underground, Biogas-CCS is considered a highly durable carbon removal pathway.

Co-benefits

• Renewable gas production alongside carbon removal
• Improved waste management and nutrient recycling
• Potential revenue diversification for biogas operators

Why Biogas-CCS matters for decarbonisation

Achieving net zero requires solutions that address emissions from sectors that cannot be fully decarbonised.

Biogas-CCS delivers negative emissions by capturing and storing CO₂ from renewable gas production, while continuing to supply energy and waste treatment services.

This makes Biogas-CCS a highly practical component of near- and medium-term decarbonisation strategies.

Benefits and challenges

Benefits

• Permanent geological storage of CO₂
• High readiness due to existing biogas infrastructure
• Clear measurement and verification
• Strong alignment with circular economy models

Challenges

• Requires access to CO₂ transport and storage infrastructure
• Project economics depend on capture integration and scale
• Permitting and coordination across value chains

How Pure Carbon Partners helps

Successful Biogas-CCS projects depend on coordination between biogas operators, capture technology providers, transport and storage partners, and buyers of carbon removal.

Pure Carbon Partners helps companies engage with Biogas-CCS in a structured and credible way.

• Identification of high-quality Biogas-CCS projects
• Assessment of capture integration and storage readiness
• Structuring of long-term offtake and removal agreements
• Support around delivery, verification, and documentation

Our role is to make Biogas-CCS procurement simple, bankable, and scalable.

Conclusion

Biogas-CCS is one of the most practical ways to deliver durable carbon removal using infrastructure that already exists.

By capturing and permanently storing biogenic CO₂ from renewable gas production, Biogas-CCS turns everyday energy and waste systems into powerful climate solutions.
