Gas separation membrane market seen reaching $3.72 billion by 2035

The global gas separation membrane market is projected to grow from $2.19 billion in 2025 to $3.72 billion by 2035 as hydrogen, carbon capture and LNG infrastructure expand. Europe is expected to post a 5.1% CAGR, supported by EU decarbonization rules and growing demand for gas purification systems.

Why it matters: - Gas separation membranes are moving from niche industrial equipment to core infrastructure for hydrogen, carbon capture and gas processing. - The market’s growth is tied to lower-energy alternatives that can cut costs and support decarbonization goals. - Europe’s 5.1% CAGR signals that EU policy is turning membrane adoption into a compliance-driven investment category.

What happened: - The global gas separation membrane market was estimated at $2.19 billion in 2025. - The market is projected to rise to $2.31 billion in 2026 and reach about $3.72 billion by 2035. - The forecast implies a 5.42% compound annual growth rate through 2035. - Europe is forecast to grow at a 5.1% CAGR, helped by EU regulatory mandates for gas purification systems in decarbonized energy networks.

The details: - The report links demand to clean hydrogen projects, carbon capture mandates, LNG buildouts and industrial gas processing. - A major catalyst is the U.S. Department of Energy’s $1.2 billion Carbon Capture Demonstration Projects Program. - Global LNG infrastructure also continues to expand, creating steady demand for membrane-based purification. - Traditional amine scrubbing and pressure swing adsorption are giving way to polymeric membranes and mixed-matrix membranes in many applications. - Membrane systems use 40% to 60% less footprint than amine scrubbers and typically consume 20% to 30% less energy. - Commercial polymeric membranes can deliver 95% to 99% hydrogen purity in single-stage configurations, while multi-stage designs can exceed 99.9%. - Purity above 99.99% usually requires a membrane-pressure swing adsorption hybrid system. - Market Research Future says the sizing model combines manufacturer shipment data, end-user procurement data, macroeconomic validation and energy infrastructure projections. - Historical figures from 2021 through 2024 come from company filings and trade association data. - Forecast values from 2026 through 2035 are based on a calibrated 5.42% CAGR. - The market rose from $1.72 billion in 2021 and is expected to reach $2.57 billion by 2028 before climbing to $3.72 billion in 2035. - Polyimide and polyamide membranes held about 36% of the market in 2025. - Polysulfone-based polymeric membranes accounted for about $460 million in 2025. - Cellulose acetate membranes are growing at a 4.8% CAGR, supported by natural gas sweetening and carbon dioxide separation projects. - Other materials, including nanostructured and mixed-matrix membranes, held about 9% of the market and may begin generating meaningful revenue around 2029 to 2031. - Nitrogen generation and oxygen enrichment held about 32% of the market in 2025. - Hydrogen recovery is the fastest-growing application, with a projected 6.1% CAGR through 2035. - Carbon dioxide removal was valued at about $390 million in 2025. - Hydrogen sulfide removal accounted for about 12% of market share. - Asia-Pacific led the market with about 38% of revenue in 2025 and is projected to grow at 6.18% annually. - North America held about 28% of global share and generated roughly $610 million in 2025. - Europe ranked third, with Germany, the United Kingdom, France, Italy, Spain, the Nordics, Russia and the rest of Europe contributing across hydrogen, biogas and carbon capture projects. - South America was valued at about $150 million in 2025, led by Brazil. - The Middle East and Africa generated about $180 million in 2025, led by Saudi Arabia and the UAE. - The market’s top five players control an estimated 55% to 65% of global revenue. - Air Liquide leads with an estimated 12% to 16% revenue share. - Air Products holds about 10% to 14%. - Evonik Industries holds about 8% to 12%. - UBE Corporation, Honeywell UOP, Parker Hannifin, Schlumberger, Fujifilm, Membrane Technology and Research, and DIC Corporation round out the competitive field. - The report includes a sample request at Request a free sample and the full report at Read the market report.

Between the lines: - The strongest demand is coming from sectors that need lower-emission gas handling without major process redesigns. - Hydrogen and carbon capture are shifting membrane technology from an efficiency upgrade to a policy-enabled necessity. - Europe’s growth rate trails Asia-Pacific, but regulatory pressure makes the region strategically important for suppliers. - Competitive advantage is increasingly tied to membrane chemistry, turnkey system integration and long-term service contracts.

What's next: - Hydrogen recovery, electrolyzer off-gas purification and steam methane reformer tail-gas recovery are expected to be the fastest-expanding niches. - Commercial revenue from advanced mixed-matrix and nanostructured membranes may begin to materialize around 2029 to 2031. - Continued LNG expansion, refinery upgrades and carbon capture project announcements should keep membrane demand elevated through the forecast period. - Europe’s decarbonization mandates are likely to keep pushing industrial buyers toward membrane-based purification systems.

The bottom line: - Gas separation membranes are becoming a key enabling technology for cleaner hydrogen, lower-carbon industry and expanded gas processing capacity.
