28 cubic metres of biogas is equivalent to one domestic LPG cylinder. Organic waste of 200 kgs can contribute one LPG cylinder daily. 1 cubic metre of gas can generate 1.5 units of electricity.Biogas is a product of decomposing organic matter, such as sewage, animal byproducts, and agricultural, industrial, and municipal solid waste. To fuel vehicles, biogas must be upgraded to a purity standard and either compressed for onsite dispensing or injected into the gas grid for distribution to dispersed fuelling locations.Biogas in India has been traditionally based on dairy manure as feedstock and these gobar gas plants have been in operation for a long period of time, especially in rural India. In the last 2-3 decades, research organisations with a focus on rural energy security have enhanced the design of the systems resulting in newer efficient low cost designs such as the Deenabandhu model.LPG (Liquefied Petroleum Gas) is a key source of cooking fuel in urban India and its prices have been increasing along with the global fuel prices. Also the heavy subsidies provided by the successive governments in promoting LPG as a domestic cooking fuel has become a financial burden renewing the focus on biogas as a cooking fuel alternative in urban establishments. This has led to the development of prefabricated digesters for modular deployments as compared to RCC and cement structures which take a longer duration to construct. Renewed focus on process technology like the Biourja process model has enhanced the stature of biogas in India as a potential alternative to LPG as primary cooking fuel. Increased Energy SecurityBiogas offsets non-renewable resources, such as coal, oil, and fossil fuel-derived natural gas. Other renewable projects like solar, wind and water depend a lot on the geography of the project location. Biogas production is location independent and the feasibility is dependent only on the feedstock, which is organic waste. Hence biogas projects are feasible irrespective of the terrain and geography.
