Bioenergy generation involves converting biomass into usable energy through different conversion processes. The major conversion processes used are thermochemical, biochemical, and physicochemical methods. These methods help in transforming organic materials such as agricultural waste, wood residues, and organic municipal waste into electricity, heat, or fuel suitable for power generation, transmission, and distribution systems. Each method has distinct operational principles and advantages depending on feedstock type and energy requirements. Thermochemical conversion processes involve the use of high temperature and chemical reactions in the absence or limited supply of oxygen to convert biomass into useful energy products. The main thermochemical methods include combustion, gasification, and pyrolysis. Combustion is the simplest process where biomass is directly burned to produce heat energy, which can be used to generate steam for electricity production in thermal power plants. Gasification converts biomass into syngas, a mixture of carbon monoxide and hydrogen, by heating biomass at high temperatures with controlled oxygen supply. Pyrolysis occurs in the absence of oxygen and produces bio-oil, biochar, and gases that can be further
