Membrane Separation Leads Biogas Cleaning Technology Market with 30-35% Share

In the technology category, membrane separation technology dominates the overall biogas cleaning equipment market with a significant 30-35% market share, owing to its relatively high operating efficiency and small footprint for biogas upgrading processes. This technology achieves high methane recovery at over 99% and has low energy use compared to conventional technologies.

The membrane separation technology has broad adoption across small to medium-sized biogas plants owing to its modular design capabilities, and minimal requirements for chemicals or other solution consumptions. The process could operate independently of membranes at times, and gives a desirable operational flexibility since it performs well in reaching pipeline-quality biomethane specifications, in which it can inject into the grid.

This increasing adoption of this technology segment is also supported by greater investment in advanced membrane materials and declining technology costs. As biomethane standards become more prescriptive and demand for decentralized upgrading systems increases, membrane separation will remain the technology of choice for the next generation of biogas cleaning installations.

CO₂ Removal Dominates Biogas Cleaning/Upgrading Applications in 2025

On the basis of application, the CO2 removal segment dominates the overall biogas cleaning equipment market at 40-45% share with a significant contribution to upgrading raw biogas to biomethane to meet natural gas grid injection and vehicle fuel expectations. The CO2 removal is critical because methane concentration needs exceed 95% and the natural gas specifications are variable depending on regional standards for natural gas applications.

In addition to increasing grid injection projects and CBM development, which provides more capacity for compressed biomethane (CBM) as transportation fuel, work is continuously conducted on CO2 removal systems that optimize methane production while driving recent energetic, biomass-specific applications.

Along with the typical injection strategies, captured carbon dioxide streams are often used for industrial applications providing additional revenue streams. Forecasts for the CO2 removal segment are very much in-line with the growing biomethane market propelling carbon utilization strategies, as this will drive the demand for biomethane and high-performance CO2 separation technology needed for biogas upgrade purposes.
