Is it feasible to have biogas as a viable source of energy in a big city like Delhi? Explain why, if yes/ no.
Answers
No, it is not feasible to have biogas as a viable source of energy in a city like Delhi
Explanation:
Biogas is a ‘green’ sustainable energy vector and has a significant role in shifting to a sustainable decarbonised society. But it is not suitable for every location. As larger production relies on an abundant supply of waste manure or crop materials, it is impractical in urban areas. Though biogas seems an obvious choice for a world that needs to cut down both waste and carbon emissions, it is not a perfect method. In addition, biogas still contains impurities even after refinement and compression. This means it can damage vehicles if used as a biofuel, as it can corrode the metal parts of the engine and increase the need for and cost of maintenance. Currently, there are no new technologies to simplify and improve the process of biogas generation, meaning that it is not a completely efficient system. Large-scale production for a wider population is not yet possible, and investment into the sector is not particularly popular with governments, which are instead putting money into the more developed alternatives of wind and solar.
