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: <strong>01_LCI</strong>: 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. <strong>02_GWI</strong>: 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. <strong>03_PB-LCIA</strong>: 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. <strong>04_LCOH</strong>: 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. <strong>05_TEA</strong>: 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. <strong>06_endpoints</strong>: 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. <strong>07_TCH</strong>: 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. <strong>08_LP</strong>: 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.本数据集关联论文《废弃聚合物制氢的环境可持续性评估》（Environmental Sustainability Assessment of Hydrogen from Waste Polymers），作者为Cecilia Salah、Selene Cobo、Javier Pérez-Ramírez与Gonzalo Guillén-Gosálbez，可通过链接https://doi.org/10.1021/acssuschemeng.2c05729获取。数据集包含正文与辅助信息中所有图表、表格所使用的可机器读取格式数值数据。 本数据集的结构按工作表逐一说明如下： **01_LCI**：对应本研究中两种气化工艺（wPG与wPG+CCS）的生命周期清单（life cycle inventories, LCI）数值，与辅助信息中表S1、S2的呈现形式一致。 **02_GWI**：对应本研究评估的13种技术的全球变暖影响（global warming impact, GWI）数值，用于生成正文中的图3。 **03_PB-LCIA**：对应本研究中13种技术的行星边界生命周期影响评估（Planetary Boundaries-Life Cycle Impact Assessment, PB-LCIA）结果。本工作表包含本研究开展的三类PB-LCIA评估数据：基于功利性缩减法的技术相对于SOS_H2,wP,b的越界水平（Transgression Level, TL）、相对于SOS_GLO的越界水平，以及基于祖父式缩减法的技术相对于SOS_H2,wP,b的越界水平。这些数据分别用于生成正文中的图4，以及辅助信息中的图S1与图S2。 **04_LCOH**：对应本研究中13种技术的平准化制氢成本（Levelized Cost of Hydrogen, LCOH）数值。本工作表包含用于生成正文中图5的数值，以及辅助信息中表S3、S4、S5所呈现的数值，这些数值用于计算PEM-BECCS、PEM-hydro与PEM-2018电网混合供电模式的平准化制氢成本。 **05_TEA**：对应wPG与wPG+CCS技术的技术经济评估（Techno-Economic Assessment, TEA）成本分项数值，用于生成辅助信息中的图S3，与辅助信息中表S6、S7、S8的呈现形式一致。 **06_endpoints**：对应不同技术按影响类别划分的总端点环境影响数值，且按工艺组分拆分。这些数值用于生成图S4，与辅助信息中表S9的呈现形式一致。 **07_TCH**：对应本研究中13种技术的总制氢成本（Total Cost of Hydrogen, TCH）数值。本工作表包含用于计算各类技术总制氢成本的数值，以及用于生成辅助信息中图S5的数据。 **08_LP**：对应在行星边界约束下优化以最小化满足全球氢能需求的成本所得的线性规划（Linear Programming, LP）结果数值。这些数值用于生成正文中的图6与辅助信息中的图S6。
