Researchers at Oregon State University filed a patent for BVR-X, a metal-organic framework that captures CO2 from humid industrial flue gas. Unlike many MOFs, BVR-X directs water and carbon dioxide to different areas inside its pores, so moisture does not block the capture sites. In tests, it held up in a highly humid stream with just 4% CO2, conditions similar to natural gas combustion exhaust. Carbon capture at factories and power plants remains expensive partly because flue gas must be dried before conventional sorbents work. BVR-X could remove that step. The material also regenerated over dozens of capture and release cycles. The work appeared in Angewandte Chemie and was supported by Saudi Aramco, the Murdock Charitable Trust, and OSU donors.
