Gas generation refers to the process of producing gas, typically through the breakdown of organic materials or fossil fuels. This can occur naturally, as in the case of biogas produced from decomposing waste, or through industrial methods like natural gas extraction from underground reservoirs. In addition to natural processes, gas generation can also involve chemical reactions, such as the conversion of coal into syngas through gasification. This generated gas can be used for various applications, including electricity generation, heating, and as a fuel for vehicles, contributing to energy needs worldwide.
