Thermodynamic and exergoeconomic analyses of a novel biomass-fired combined cycle with solar energy and hydrogen and freshwater production in sports arenas

Abstract

In this article to tackle the main concerns of today's world as fossil fuel shortage, environmental impacts of fossil fuels like global warming and atmosphere pollution as well as water scarcity, a novel power plant is designed. In this regard, the proposed plant comprises of biomass gasification unit, photovoltaic thermal collectors, a proton exchange membrane hydrogen production unit, as well as a reverse osmosis water purification plant. The plant is named as (biomass-fired combined cycle with photovoltaic, thermal collectors, hydrogen production, and reverse osmosis) BCPVHR and to assess its performance, energy, exergy, exergoeconomic, and environmental analyses are performed. The varying parameters are compressor pressure ratio and gas turbine inlet temperature. These two parameters' impact on energy efficiency, exergy efficiency, net generated power, fresh water production, total unit product cost as well and environmental index are assessed. The results are useful for adjusting the compressor pressure ratio and gas turbine inlet temperature. Please note that this plant is designed to be used completely or partially in sports facilities and can be a valuable endeavor for managing sports facilities to use renewable energy in their construction. Meanwhile, based on the priories of products different values of parameters can be used. Increasing the compressor pressure ratio raises the total unit product cost and the environmental index until 11.5 decreases and later increases. Increasing the gas turbine inlet temperature decreases the both total unit product cost and environmental index which reach 65 $/GJ and 65 kg/kWh, respectively. © 2024 Hydrogen Energy Publications LLC
