Porous liquids could capture methane from biogas and release it on demand

Jessica Rimsza, a materials engineer at Sandia National Laboratories, sees untapped potential in what most people see as waste. Food scraps, manure and sewage are natural byproducts of the U.S. agricultural industry. They are also rich in biogas, a mixture that contains methane and other valuable chemicals. Rimsza and a team of researchers at Sandia are developing chemistry that could help capture methane from biogas and separate it from other gases so it can be put to good use.
