Osmoses, a Massachusetts Institute of Technology spinoff, has created a membrane material thinner than human hair to reduce carbon emissions from industrial processes such as natural gas production.

Today, businesses use an energy-intensive technique called separation to filter out the valuable methane from other gases. That often requires using fossil fuels to boil off the unwanted chemicals — a process that can account for as much as 15% of world energy demand, according to a 2016 study.
