Biogas is a sustainable energy source that produces organic anaerobic digestion. At present, biogas can only be used where it is produced. Therefore, the transport of biogas is a big need. This can be done by compressing the gas in the cylinder. Therefore, in this study, the production of biogas from bovine and sheep wastes was examined and a system for storage and compression of biogas was presented. In order to conduct experiments, a 925-liter quench digester and a 30-day time limit were used in this study. Experiments were performed in 10 different treatments. According to the results of the study on the production of biogas from bovine and sheep wastes at a loading rate of 1.4, the highest yield of biogas as well as the energy efficiency of treatment D (feeding of bovine wastes at a temperature of 30-40 C? using a mixer) With a value of 333 L * DAY-1 and 26.89488128 L*Mj-1 and the highest ratio of energy related to treatment B (feeding of bovine wastes at a temperature of 20-30 C° with agitator) was about 1.011. The compressed and stored biogas system was introduced. The comparison between storage and compression between conventional natural gas in the market by storing and compressing biosPHere inside the capsule shows that the characteristics of the produced biogas as well as the type of compressor as well as compression pressure have a significant effect on storage of biogas. Biogas storage technology is economically feasible, and based on natural gas, this gas is produced without any costs. This is because the biogas production cost is minimal, as the actual price of biogas (273 Toman) is even lower than the domestic price of natural gas (300 Toman). Biogas storage capsules are also economically viable alternatives to natural gas capsules. Different methods of purification and enrichment have been investigated, using these methods, biogas of methane enriched and equivalent to natural gas. It can be used for all applications that are used to use natural gas. As fuel for vehicles, combined power and heat power plants, CHP, power generation, and so on. In this research, the potential of biogas production from cattle and sheep wastes, as well as energy consumption per household during the year in the city of evan garb, was investigated. Based on the findings of this research, if all the total animal waste collected per household is used during the year, the biogas volume will be equivalent to 9343.44 M3, which will have an equivalent energy of 55686.90 KWh. Also, the energy consumption of each household per year was calculated from three inputs of wood, kerosene and liquid gas equivalent to 37374.6 hours KWh. The concept of the above findings is that given this amount of potential for production and energy consumption, on average, each household per year can generate excess energy for another household.
