Setting Thresholds to Define Indifferences and Preferences in PROMETHEE for Life Cycle Sustainability Assessment of European Hydrogen Production

The Life Cycle Sustainability Assessment (LCSA) is a proven method for sustainability assessment. However, the interpretation phase of an LCSA challenging because many different single results are obtained. Additionally, performing Multi-Criteria Decision Analysis (MCDA) one way—not only LCSA—to gain clarity about how to interpret results. One common form MCDAs outranking methods. For these type methods it becomes utmost importance clarify when become preferable. Thus, thresholds commonly used prevent decisions based on that actually indifferent between analyzed options. In this paper, new approach presented identify and quantify such Preference Ranking Organization METHod Enrichment Evaluation (PROMETHEE) uncertainty Impact (LCIA) Common discussed using case study finding preferred location sustainable industrial hydrogen production, comparing three locations in European countries. indicated preferences environmental, economic social application PROMETHEE helped find clear solution. comparison newly-specified LCIA with default provided important insights regarding production.
