Biogas is a kind of clean energy. Reasonable development and utilization can protect the environment. Every country in the world is working hard. Next, we will follow the manufacturer of biogas purification equipment to learn about the development status of biogas purification technology abroad!
瑞典在沼气提纯领域处于地位，是沼气净化提纯用于车用燃气先进的国家。早在1996年，瑞典就已将沼气净化提纯至甲烷含量在95%以上，并作为汽车燃料使用。2010年，瑞典沼气年总产量折合1.3亿m3天然气当量，占燃气消费总量的13%。2010年瑞典全国使用压缩生物天然气的车辆有7万辆，加气站500个。瑞典计划到2020年，50%天然气将由生物燃气替代，2060 年天然气将完全被生物燃气替代。此外，瑞典政府对沼气用作车用生物燃气有一系列的优惠政策，包括免征能源税、H2S 排放税和CO2排放税，减收气体燃料的车辆使用税等；购买生物燃气汽车可享受政府购车补贴，以及一些区域性的优惠政策，如免交拥堵费和停车费。
Sweden is in the leading position in the field of biogas purification, and is an advanced country in biogas purification and purification for automotive gas. As early as 1996, Sweden purified biogas to more than 95% methane and used it as automobile fuel. In 2010, Sweden's total annual methane production was equivalent to 130 million m3 natural gas equivalent, accounting for 13% of the total gas consumption. In 2010, there were 70,000 vehicles using compressed biogas and 500 gas stations in Sweden. Sweden plans to replace 50% of natural gas by biogas by 2020 and completely by biogas by 2060. In addition, the Swedish government has a series of preferential policies for biogas used as vehicle biogas, including exemption of energy tax, H2S emission tax and CO2 emission tax, reduction of vehicle use tax for gas fuel, government subsidies for buying biogas vehicles, and some regional preferential policies, such as congestion free and parking. The fare.
German biogas engineering technology is in the leading position in the world. The biogas industry has developed rapidly in the past 15 years. By 2011, there are about 7000 biogas projects in Germany. Biogas produced by German biogas factories is mainly used for generating electricity and networking. By 2010, the total installed capacity of biogas power generation reached 2300 MW, with an annual power generation capacity of 20 billion kW. h, accounting for 1.5% of Germany. At present, the utilization of biogas in Germany has changed from cogeneration of heat and power directly driven by generators to production of pipeline biogas and vehicle gas. Since 2006, the first two biomethane plants in Germany have been integrated into the national natural gas pipeline. By 2011, about 83 biogas projects have purified biomethane into biomethane. The total amount of biomethane purification is about 460 million m3. It is expected that more biogas purification and purification projects will be implemented in the next few years. In addition, Germany has set a target of 6 billion m3 and 10 billion m3 for biomethane production in 2020 and 2030, respectively. By 2020, biomethane will replace 6% of the total national natural gas consumption.
In addition, Switzerland, Denmark, Canada and other countries are also countries with fast development of biogas purification technology in the world, with advanced purification technology and equipment.
