The folder contains the output data relative to the paper: Water footprint and scarcity risks of low-carbon fuels Authors: Lorenzo Rosa, Andrea Citrini, Tom Terlouw * Corresponding Author Email address: lrosa@carnegiescience.edu CONTENTS: Figure_2: Direct and indirect water consumption of selected low-carbon hydrogen production pathways (m³/t H₂) Figure_3: Direct and indirect water consumption of selected conventional and potentially low-carbon ammonia production pathways (m³/t NH₃) Figure_4: Direct and indirect water consumption of selected conventional and potentially low-carbon methanol production pathways (m³/t MeOH) Figure_5: Database of the facilities considered in this study, including production, total hydrogen demand, water consumption (m³/yr), and number of months under water scarcity for the baseline year (2020) and for 2050 under both SSP1-2.6 and SSP5-8.5 scenarios. For future scenarios, ensemble median values as well as the 25th and 75th percentiles are provided. Figure_6a: Water-scarcity-affected production for North American ammonia facilities. For each state, the 2020 baseline and the 2050 projections under SSP1-2.6 and SSP5-8.5 are provided as ensemble median values (Mt/yr), together with the 25th and 75th percentiles for the future scenarios. Figure_6b: Water-scarcity-affected production for North American refinery facilities. For each state, the 2020 baseline and the 2050 projections under SSP1-2.6 and SSP5-8.5 are provided as ensemble median values (barrels/yr), together with the 25th and 75th percentiles for the future scenarios. Figure_6c: Water-scarcity-affected production for North American methanol facilities. For each state, the 2020 baseline and the 2050 projections under SSP1-2.6 and SSP5-8.5 are provided as ensemble median values (Mt/yr), together with the 25th and 75th percentiles for the future scenarios. Figure_7: Correspondence between the facility database and active grid cells. For each active cell, the baseline water consumption composition across North America is provided for seven sectors—irrigation, municipal, mining, manufacturing, livestock, facilities, and electric generation (m³/yr).
