Biogas production in Europe has grown significantly, driven by renewable energy policies and economic, environmental, and climate benefits. In 2015, biogas production reached 18 billion cubic meters of methane, accounting for half of global production. The EU is the world leader in biogas electricity production, with over 10 GW of installed capacity and 17,400 biogas plants. Biogas delivered 127 TJ of heat and 61 TWh of electricity in 2015, with about 50% of total biogas consumption used for heat generation. Europe is the leading producer of biomethane for transport and gas grid injection, with 459 plants producing 1.2 billion cubic meters in 2015 and 340 plants feeding into the gas grid with a capacity of 1.5 million cubic meters. About 697 biomethane filling stations ensured the use of 160 million cubic meters of biomethane as a transport fuel in 2015. Biogas is produced through anaerobic digestion of organic materials, including agricultural and industrial waste, municipal organic waste, and sewage sludge. Anaerobic digestion provides opportunities for biogas to be used for electricity, heat, and fuel, with additional economic, environmental, and climate benefits. In Europe, most modern anaerobic digesters provide electricity and heat in electricity-only, heat-only, or combined heat and power (CHP) plants. Anaerobic digesters are mostly connected to gas-fired engines for heat and power generation, with electrical capacities ranging from tens of kW to a few MW. The heat generated can be used for local heating or delivered to external users. Biogas can be upgraded to biomethane and injected into natural gas networks or used in transport vehicles, with proper purification to remove trace gases such as H2S, water, and CO2. Biogas production has increased in the EU, encouraged by renewable energy policies, and is expected to contribute significantly to renewable energy targets. The EU has set targets for 2030, including a 40% reduction in GHG emissions compared to 1990 levels and a 27% share of renewable energy consumption. The EU is also the world leader in biogas electricity production, with 10.4 GW of installed capacity in Europe alone. Biogas is used for electricity generation, heat production, and transport, with biomethane being a key component in the transport sector. The use of biomethane as a transport fuel is increasing, with 160 million cubic meters used in 2015. The European Union has a significant potential for biogas production, with estimates of up to 200–250 billion cubic meters annually.
