Oregon State Researchers Develop BVR-X Carbon Capture Material That Works in Humid Flue Gas

Researchers at Oregon State University have developed BVR-X, a metal-organic framework carbon capture material designed to keep working in humid industrial flue gas. Humidity normally blocks CO2 adsorption in MOFs, forcing facilities to dry flue gas first at extra cost. BVR-X separates water and CO2 into different pore regions, so the material keeps capturing CO2 without that drying step. In tests with a highly humid gas stream containing 4% CO2, a level relevant to natural gas combustion, BVR-X continued to capture CO2 and stayed effective through dozens of capture and regeneration cycles. The university has filed a patent application. The research was published in Angewandte Chemie and supported by Saudi Aramco and other funders.
