Sustainability Decision Support Framework for the Prioritization of Hydrogen Energy Systems

This chapter proposed a multicriteria decision-making methodology for the sustainability prioritization of industrial systems. The methodology incorporates a fuzzy analytic hierarchy process method that allows the users to assess the soft criteria by using linguistic terms. A fuzzy analytic network process method is used to calculate the weights of each criterion, which can tackle the interdependencies and interactions among the criteria. The preference ranking organization method for enrichment evaluation approach is used to prioritize the sustainability sequence of the alternative systems. Moreover, a sensitivity analysis method was developed to investigate the most critical and sensitive criteria. The developed methodology was illustrated by a case study to rank the sustainability of five alternative hydrogen production technologies. The advantages of the developed methodology over the previous approaches were demonstrated by comparing the results determined by the proposed framework with those determined by using the pervious approaches.
