Development of a Novel Biomass-Wind Energy System for Clean Hydrogen Production along with Other Useful Products for a Residential Community

The study presents the development of a novel integrated wind-biomass energy system designed for sustainable urban development, leveraging municipality waste and wind power energy sources. This innovative system is capable of producing multiple forms of energy, including electricity, cooling, heat, and hydrogen, addressing the diverse energy needs of urban communities. It integrates advanced thermodynamic cycles like Kalina and water electrolysis via an alkaline electrolyzer. In addition, the system uniquely combines power and refrigeration while utilizing landfills as an energy source. The designed system is thermodynamically modeled using the Engineering Equation Solver and process wise simulated by the Aspen Plus software to ensure better performance. By integrating advanced thermodynamic cycles, such as the Kalina and combined power and refrigeration system, the overall system is designed to maximize the utilization of biomass energy content and enhances overall performance. The thermodynamic analysis results reveal that the system achieved remarkable results with an energy efficiency of 67.60% and an exergy efficiency of 59.7%, demonstrating its tangible performance compared to other standalone energy systems. The refrigeration system itself achieves an energetic COP of 5.41 and an exergetic COP of 1.7. Additionally, the system's hydrogen production, facilitated by an alkaline electrolyzer, reaches a rate of 5.38 kg/h, highlighting its potential to contribute to clean hydrogen energy solutions. Moreover, the exergo-environmental assessment shows that the system is environmentally friendly. The cost assessment shows that the system reaches profitability in 7 years and demonstrates growth, achieving a substantial NPV of 192.39 million by 30 years, highlighting its long-term financial viability.
