During the 1970-1990 years, about 140 biogas projects were built, mainly for energy. However, due to poor facilities, non-standard design, unreasonable installation and poor management, most of these early biogas fermentation tanks have been scrapped or discontinued. In 2007, there are about 111 biogas projects running normally. Basically, biogas power generation projects in livestock and poultry farms generate 215 million Kwh equivalent energy per year. (37 million 880 thousand, m3/a) I. the form of combined heat and power (CHP) In Germany, 98% of biogas projects are combined heat and power (CHP) Two. Vehicle fuels Sweden is the most common country for the use of biogas as the fuel for automobiles. Biogas as a fuel for automobiles began in 1996 and built a standard for motor fuel biogas. Starting in 2004, trains began to operate this way. In 2007, there were 14400 biogas fuel vehicles. In 2007, biogas for transport fuels in Sweden reached 280 million Nm3, accounting for 19% of biogas production. There were 86 common vehicles, biogas filling stations, and 27 bus gas filling stations Three. Municipal gas Germanys energy economy law clearly defined biogas as gas. In March 12, 2008, by the new law, the new biogas and gas network in 2030, 10% of the biogas as an alternative to natural gas. Most cost shall be borne by the Gas Co. In Germany in 2009 there have been 100 biogas biogas into natural gas network, Subsidies: 350Nm3/h, subsidies 2, Europe sub /kwh, to reach 700Nm3/h, subsidies 1 euro cents /kwh. Denmark subsidies 5.4 cents /kwh. There are 4 methane purification stations in Sweden, and purified biogas is fed into the gas pipeline network. The Nordic countries still have arguments over whether or not biogas should be purified for use in grid
