[en] More than 1000 biomethane facilities were operating in Europe by the end of 2021, with a total production capacity of 3.6 billion cubic meters. Of these units, 90% inject the biomethane they produce into the gas transmission network, representing 30 TWh in 2021. European biomethane producers have now reached 10% of the 2030 REPowerEU plan target of 35 bcm announced by the European Commission. There is huge scope to expand biomethane production, as only 5% of biogas plants in the EU have registered a biogas upgrading unit, which is required to produce biomethane. The majority of biomethane plants are supplied by agricultural residues including manure, crop residues and sequential crops. Biomethane production is currently fueled by 38% agricultural residues, 31% dedicated energy crops and 28% organic waste. The sector has grown steadily in recent years with total biogas upgrading capacity increasing by 21% in just two years. This mainly results from dynamic growth in major producing countries like France or the Netherlands. Smaller players like Italy are following that same dynamic trend. In France alone, 241 new biomethane units have been commissioned in the past two years. Regarding feedstocks, the proportion of energy crops has decreased substantially over the past decade while the use of agricultural residues has increased, improving the sector's sustainability. Countries with developed biomethane industries are transitioning from investment subsidies and feed-in tariffs to tendering systems that encourage the industry to reduce its costs and be less dependent on support mechanisms. Some countries are also stimulating demand for biomethane used as fuel through consumption and carbon tax exemptions, as well as increasing quotas for renewable fuels as required by the Renewable Energy Directive (RED II). Meanwhile, an increasing number of national registers tracking biomethane production are enabling the development of Guarantees of Origin (GOs) and Renewable Transport Fuel Certificates. In addition, the possibility to use GOs in the EU ETS as introduced in the Monitoring and Reporting Regulation (MRR) Directive and the potential implementation of the Union Database in 2023 as quoted in RED II, could boost respectively the development of the two types of certificates
