Experimental Investigation on Biogas Operated Electric Vehicle Charging Station

Abstract

Biogas is developing as a possible replacement for fossil fuels as the globe shifts to sustainable energy sources. Organic waste, including food waste, agricultural waste, and sewage, decomposes to produce biogas. Biogas is a fuel that can be used to create electricity, heat homes, and power vehicles. The popularity of electric cars (EVs) is rising as a result of their zero emissions. EVs and biogas can work together to create a sustainable transportation option. The viability of EV charging stations powered by biogas is the main topic of this techno-economic inquiry. The study involves the evaluation of the technical and economic elements of the proposed system. The technical aspects cover power generation, the EV charging system, the biogas storage system, the biogas production process, and the biogas purification process. The capital cost, operating cost, and revenue from the charging station are all considered economic factors. The collection and processing of organic waste is a step in the creation of biogas. Impurities from the biogas are removed during the purification process, including carbon dioxide and hydrogen sulphide. The compressed version of the purified biogas is next stored in a storage system before being used to power a biogas generator. EVs are charged using the electricity generated. The economic study of the proposed system covers the capital cost, which includes the cost of equipment, installation, and site purchase. The cost of producing biogas, producing power, and performing maintenance are all included in the operational cost. The revenue earned from the charging station comprises the income generated from charging EVs. According to the study, an EV charging station powered by biogas is a workable option for sustainable transportation. Due to the high cost of equipment and installation, the system has a high capital cost. But so far, because power and biogas production are inexpensive, the system has low operational costs. Over time, the charging station's revenue may yield a return on investment. In order to increase system efficiency and lower system costs, the study suggests additional research on the optimization of the biogas production process, the biogas purification process, and the power generation system.
