Comparative Analysis on Bioelectricity Production by Using a Multi-Chambered Biomass

The study investigates the electrical performance of a biomass battery using different biomass substrates. This method of generating electricity can be employed to meet the lighting requirements of rural households using accessible biomass materials. The process involves the anaerobic breakdown of biomass, which produces ions that drive the generation of power. The production of bioelectricity was tested using Azolla with water in a 5:5 ratio, a mixture of Azolla and cow dung in a 2.5:2.5:5 ratio with water, Pistia with water in a 5:5 ratio, Pistia combined with cow dung in a 2.5:2.5:5 ratio with water, cow dung in a 5:5 ratio with water, and a blend of Azolla, Pistia, and cow dung with water in a 2:2:2:4 ratio. The biomass battery, designed with multiple chambers, utilized zinc plate and carbon rod electrodes to generate bioelectricity from the substrates. The study compared the substrates based on output voltage, current, internal resistance, power density, and the practicality of each.
