“…Other secondary systems were excluded because of data availability. It is recognized that such stages have negligible effects if distributed over their operational lifespan [26]. Different system configurations were modeled to check the sensitivity of the results.…”

A common sustainability issue, arising in production systems, is the efficient use of resources for providing goods or services. With the increased interest in a hydrogen (H 2 ) economy, the life-cycle environmental performance of H 2 production has special significance for assisting in identifying opportunities to improve environmental performance and to guide challenging decisions and select between technology paths. Life cycle impact assessment methods are rapidly evolving to analyze multiple environmental impacts of the production of products or processes. This study marks the first step in developing process-based streamlined life cycle analysis (LCA) of several H 2 production pathways combining life cycle impacts at the midpoint (17 problem-oriented) and endpoint (3 damage-oriented) levels using the state-of-the-art impact assessment method ReCiPe 2016. Steam reforming of natural gas, coal gasification, water electrolysis via proton exchange membrane fuel cell (PEM), solid oxide electrolyzer cell (SOEC), biomass gasification and reforming, and dark fermentation of lignocellulosic biomass were analyzed. An innovative aspect is developed in this study is an analysis of water consumption associated with H 2 production pathways by life-cycle stage to provide a better understanding of the life cycle water-related impacts on human health and natural environment. For water-related scope, Water scarcity footprint (WSF) quantified using Available WAter REmaining (AWARE) method was applied as a stand-alone indicator. The paper discusses the strengths and weaknesses of each production pathway, identify the drivers of environmental impact, quantify midpoint environmental impact and its influence on the endpoint environmental performance. The findings of this study could serve as a useful theoretical reference and practical basis to decision-makers of potential environmental impacts of H 2 production systems.

“…Rosen [26] computed 78.5% efficiency of an SMR system which includes PSA, CO 2 sorption as purification unit after shift reactor and methanation. Bargigli et al [28] compared different hydrogen production pathways and reported exergy efficiency values of 43 up to 71%.…”

“…However, the traditional method for producing hydrogen or syngas from coal, i.e., using natural gas and biomass, is not energy-efficient because it requires heating the reactants to a relatively high temperature [1]. For example, in the Koppers-Totzek coal gasification process, pulverized coal is rapidly partially oxidized with oxygen and steam at essentially atmospheric pressure and at a temperature of 1750 K [2].…”
