New international hubs, routes and trade of renewable and decarbonised gas are arising. In the future European Energy hubs, established in regions with exceptional conditions for renewable energy production, will interconnect offshore production facilities with the use of existing gas infrastructure. An international trading platform for renewable gases will exist and new molecule renewable/decarbonized energy carriers, provided from new world wide energy hubs, are going to supply the european market establishing new routes of trade. We are looking for contributions that best describe this transition and individual aspects thereof.
