A comprehensive exergoenvironment-emergoeconomic-emergoenvironment based analysis of hybrid steam biomass gasification and solid oxide fuel cell system for a multigeneration system

Abstract

The present study focused on the exergoenvironmental analysis via Life Cycle Assessment and emergy based evaluation of a multigeneration system of hydrogen, carbon dioxide, and power through biomass gasification (Sawdust). In this regards, energy, exergy, exergoeconomic, exergoenvironmental, emergoeconomic, and emergoenvironmental modeled in MATLAB software for a considered multigeneration system, is to employ hydrogen in a solid oxide fuel cell to increase power yield and to generate hydrogen and CO2 as output products. The Life Cycle Assessment for exergoenvironmental analysis has been performed in SIMA Pro based on Ecoindicator 99. Sensitivity analysis has been performed for the main decision variables of the considered multigeneration system based on energy, exergy, exergoeconomic, exergoenvironmental, emergoeconomic, and emergoenvironmental assessment.
