Exergoeconomic evaluation of a new carbon-free hydrogen and freshwater production system based on biomass gasification process

Abstract This article is based on the conceptual-thermodynamic design and exergoeconomic investigation of a new poly-generation system driven by biomass fuel (i.e. wood). In proposed energy system, Rankine power process, gasification desalination process multi-effect desalination, MED) water electrolyzer solid oxide cell, SOEC) are installed in hybrid form. Electric energy, fresh hydrogen gas useful output products system. The indicates an innovative framework for carbon-free production these products, which introduces environmentally friendly efficient schematic. findings research indicated that capable producing more than 1.8 MW electric power. Other include water, were calculated as 0.0036 kg/s 9.92 m3/h, respectively. It was also can achieve energetic exergetic efficiencies equal to 37.1% 17.8%, total unit exergy cost destruction rate 15.9$/GJ 8640 kW, Parametric analysis presented order identify input variables affecting performance Further, behavior under four different types evaluated compared.
