Environmental Sustainability Assessment of Hydrogen from Waste Polymers

Dataset associated with the publication "Environmental Sustainability Assessment of Hydrogen from Waste Polymers" by Cecilia Salah, Selene Cobo, Javier Pérez-Ramírez, and Gonzalo Guillén-Gosálbez, available at https://doi.org/10.1021/acssuschemeng.2c05729. The dataset includes the numeric data used both in figures and tables of the main text and the supporting information, in a machine-readable format.

The structure of the dataset is here elucidated sheet by sheet:

• 01_LCI: numerical values associated with the life cycle inventories of the two gasification processes presented in this work (wPG and wPG+CCS). These values are displayed as in Tables S1 and S2 in the Supporting Information.
• 02_GWI: numerical values associated with the global warming impact of the 13 technologies assessed in this study. These values are used to generate Figure 3 of the main text.
• 03_PB-LCIA: numerical values associated with the results from the planetary boundaries life cycle impact assessment of the 13 technologies assessed in this study.  This sheet contains data on all three PB-LCIA assessments carried out in this work: transgression level (TL) of the technologies relative to SOS_H2,wP,b following a utilitarian downscaling, the TL of the technologies relative to SOS_GLO, and the TL of the technologies relative to SOS_H2,wP,b downscaled following the grand-fathering downscaling. These values are used to generate respectively Figure 4 of the main text, and Figures S1 and S2 in the Supporting Information.
• 04_LCOH: numerical values associated with the levelized cost of hydrogen (LCOH) of the 13 technologies assessed in this work. The sheet contains the values used to generate Figure 5 of the main text, and the values as displayed in Tables S3, S4, and S5 in the Supporting Information, which are used to calculate the LCOH of PEM-BECCS, PEM-hydro and PEM-2018 grid mix.
• 05_TEA: numerical values associated with the cost breakdown of the wPG and wPG+CCS technologies. These values are used to generate Figure S3 in the Supporting Information, and are displayed as in Tables S6, S7 and S8 in the Supporting Information.
• 06_endpoints: numerical values associated with the total endpoint environmental impacts of the different technologies per impact category, broken down by process component. These values are used to generate Figure S4, and are displayed as in Table S9 in the Supporting Information.
• 07_TCH: numerical values associated with the total cost of hydrogen (TCH) of the 13 technologies assessed in this work. The sheet contains the values used to calculate the TCH of the different technologies, and the data used to generate Figure S5 in the Supporting Information.
• 08_LP: numerical values associated with the results of the optimization that minimizes the cost of meeting the global H₂ demand within planetary boundaries. These values are used to generate Figure 6 of the main text and Figure S6 in the Supporting Information.
