Use of membranes in the implementation of the "Power to gas" concept

This paper presents the possibility of membrane use in the Power to Gas concept.Power to Gas is a concept of electrical energy conversion into the gaseous methane by well known Sabatier reaction. This reaction needs pure reagents such as carbon dioxide and hydrogen. The polymeric dense membranes could be used to obtain pure carbon dioxide from the stream of biogas or flue gas. The products of this reaction are methane and water. For methane dewatering one could also use polymeric membranes. The paper presents literature data as well as the Author’s own research results.
