LCA Goal and Scope:In LCA goal and scope step it is important to define the objective of the analysis, functional unit (FU) and system boundary. The goal of this study is to evaluate the environmental impact of all processes involved in hydrogen production from natural gas. The functional unit (FU) provide a basis for calculating the inputs and outputs. In this work, a common FU of 1 kg of hydrogen produced was selected (Galera & Gutiérrez Ortiz, 2015; Verma & Kumar, 2015). The system boundaries on the other hand, determined the process units to be included within the evaluated system. The system boundaries for this system is shown in Figure 2. It is a cradleto-grave approach which starts from methane feedstock until hydrogen storage. In detail, the system boundaries consist of five subsystems namely methane feedstock (SB1), hydrogen production (SB2), process steam (SB3), solvent absorption (SB4) and process water plant (SB5). Note that, the construction and commissioning phases as well as energy consumptions were excluded from the analysis and will be our future work
