Researchers from MIT are developing graphene based membranes for gas separation. They expect those membranes to have very high permeance which would lead into high energy efficiency. The membranes will also have a high degree of selectivity through size exclusion. The research will focus on separating methane from hydrogen at first - which is useful for natural gas processing.

This research was just granted some seed money and will last for 2 years.
