According to a recent study published by the consulting firm Ecofys – and commissioned by the Gas for Climate consortium – 25% of the current natural gas consumption in Europe can be replaced by renewable gas by 2050. The research has identified the role of the latter in a completely decarbonized energy system, and it has assumed that, in within thirty years, all the European countries will have concentrated their resources on the production from renewable sources and on the adoption CCS (Carbon Capture and Storage) and CCU (Carbon Capture and Utilization) systems for traditional electrical installations. Thus, the net carbon emissions will be equal zero. Furthermore, the authors of the research have calculated that renewable gas production can be increased to 122 billion cubic meters per year by 2050. In addition, if not considering the industrial sector, it would be enough to use only 72 billion cubic meters out of 122 total in order to heat buildings and to produce electricity that can be used in times of peak energy demand, saving up to 138 billion euros. Finally, the study provides an estimate of the sustainable production potential of biomethane in the European Union: by 2050 it will be equal to 98 billion cubic meters (1072 TWh) of energy per year, while the production of renewable hydrogen, which uses wind and photovoltaic energy, will be 24 billion cubic meters.
