Technology Options
Membrane Technology
Their membrane system separates carbon dioxide from methane through selective gas permeation. CO₂ passes through the membrane surface more quickly than methane, which is retained and collected as product gas.
This plug-and-play solution requires no additional operating resources such as water or heat, making it ideal for sites with limited utilities.
Amine Scrubbing
Their chemical process uses an amine solution that absorbs carbon dioxide as raw gas flows through a packed column. This technology achieves biomethane purity up to 99.9% and is particularly suitable for sites with available heat sources.
The process is highly robust when handling impurities in the biogas stream and offers exceptional plant availability.

Final Considerations When Choosing a Biomethane Upgrading Supplier
When selecting a biomethane upgrading equipment supplier, consider these key factors beyond just the initial purchase price:
- Technology match: Different upgrading technologies have varying strengths depending on your specific feedstock, flow rate, and end-use requirements.
- Energy efficiency: Operating costs over the system's lifetime often exceed the initial investment, making energy-efficient designs crucial for long-term profitability.
- Methane recovery: Even small differences in methane slip can significantly impact both revenue and environmental performance.
- Scalability: Consider future expansion possibilities and whether the system can be upgraded to handle increased capacity.
- Service and support: Local technical support, spare parts availability, and remote monitoring capabilities are essential for maintaining high uptime.
- Track record: Suppliers with proven installations similar to your planned operation reduce implementation risk.
For agricultural operators, biomethane upgrading represents a significant opportunity to diversify revenue streams beyond electricity generation. While the initial investment is higher than a CHP system, the potential returns through biomethane sales, carbon credits, and in some regions, renewable fuel incentives can provide a compelling business case.
The technology has now matured to the point where small-scale operations can benefit from the same upgrading processes previously only economical for large facilities. With solutions available starting from just 40 Nm³/h, even modest farm-based biogas plants can transform their raw biogas into valuable biomethane for grid injection or vehicle fuel.
