Project summary description:
By innovatively incorporating plasma and novel graphene solar thermal heating into a CSIRO invented low temperature CO2 methanation process, the project goal is to invent a highly cost effective and energy efficient process as a game changer to produce renewable energy carriers to promote H2 uptake by market and aid decarbonisation efforts.
