Biogas is a type of renewable energy that belongs to the category of biofuels produced naturally from the decomposition of organic waste in the absence of oxygen, called anaerobic digestion. Anaerobic digestion is a natural form of waste-to-energy that uses the fermentation process to break down organic matter. Biogas generated by anaerobic digestion processes is a clean and environmentally friendly renewable fuel. There are currently various beneficial options for using biogas thanks to technological advances. The most common uses of biogas are electricity generation and heat production. Thanks to new technologies, it can be converted into renewable natural gas and compressed renewable natural gas, as well as for use as fuel for vehicles. Say no to plagiarism.

A small biogas system can provide the thermal energy needed for simple household activities by simply adjusting the air/gas ratio in a conventional gas burner. According to the handbook "Sustainable use of heat from biogas plants" by Dominik Rutz, biogas can be used as fuel for a combined heat and power (CHP) plant, which is a simultaneous production of electricity with heat recovery and use. Basically, it is a gasoline engine with a generator connected to it. The engine drives the generator, which in turn produces electricity. Through internal combustion, the gas engine also generates heat. This heat leaves the engine through the exhaust gases and coolant. By using heat exchangers, this thermal energy can be captured and used productively. An engine-based cogeneration unit has an efficiency of up to 90% and produces approximately 35% electricity and 65% heat. Compared to natural gas, biogas is generally of lower quality. Its calorific value is lower. Additionally, biogas may also contain contaminants harmful to the engine, such as sulfur compounds, halide compounds, acids and solids, which often leads to the treatment of biogas to reduce the level of contamination and improve the performance and lifespan of the gas engine. . This renewable energy is already used for the production of heat and electricity, but the best solution for valorizing this clean energy is its use as fuel for vehicles. Gasoline vehicles can use biogas as fuel, but the biogas must be converted into natural gas for use in normal vehicles designed to use natural gas. Gas valorization is normally carried out in two stages, the main stage being the CO2 removal process. Minor contaminants are normally removed before CO2 removal and the water dew point can be adjusted before or after valorization (depending on the process). The second stage is H2S removal in which ferrous materials (material made of iron) are placed in a closed, gas-tight container to be purified. Suryavanshi ND Shaha, professor at the faculty of mechanical engineering at SVPM, said biogas has a very high octane number, around 130. In comparison, gasoline is 90 to 94 and alcohol is 105 to better. This means that a higher compression ratio can be used with biogas than with gasoline. The compression ratio of an engine.
