ONTRAS is leading a consortium (DBI, ONTRAS, Mitnetz Gas, GRTGaz, DVGW) aimed at developing a gas filter separating methane and hydrogen com-pounds from a mixed gas stream. The objective is to build a pilot set of membranes for the separation
of hydrogen in hydrogen-natural gas mixtures with high purity. The tests will start in 2020.
Research are ongoing to economically evaluate such a membrane and to test it with different materials.
