📄 Abstract（原文）
This repository contains the data and code supporting the article “The metal basis of the methanol economy” by A. Nabera, R. Istrate, A.J. Martín, J. Pérez‑Ramírez, and G. Guillén‑Gosálbez (Chem Circularity). The study uses dynamic material flow analysis to quantify the metal demand of a global methanol economy from 2025 to 2050. In this economy, methanol produced from green hydrogen and CO₂ from direct air capture (DAC) supplies chemicals, road transport, aviation, and shipping. The model covers 114 technology configurations, which combine: power supply (wind, PV, or grid), with lithium‑ion battery storage for wind and PV, water electrolysis (PEM, AE, or SOEC), DAC (HT or LT), methanol synthesis catalysts. Installed capacities follow a logistic ramp‑up. Retirements follow three‑parameter Weibull lifetime distributions, and end‑of‑life flows can be recycled. For 26 metals, cumulative demand to 2050 is compared with cumulative production and reserves. Each metal is also evaluated by the governance of its producing countries. Data technology_data_methanol_economy.xlsx : product demand in 2025 and growth rates, methanol requirements per product, and auxiliary electricity requirements. material_intensity_data.xlsx : material intensities for 2025 and 2050 (including grid milestones), technology lifetimes, metal recycling rates, and metal production and reserves. geographical_data.xlsx : mine production by country, production shares, and governance scores derived from the World Bank Worldwide Governance Indicators. Code (Jupyter notebooks, run in order) 00_resource_demand_calculations.ipynb : methanol, hydrogen, CO₂, and electricity demand, plus the installed capacities of power generation, batteries, and electrolyzers. 01_material_intensity_calculations.ipynb : annual material intensities interpolated over 2025–2100. 02_dynamic_stock_flows.ipynb : stock, inflows, and outflows for each technology, and the resulting virgin, recycled, and net metal demand. 03_plot_figures.ipynb : figures in the main text. 04_supplementary_plot_figures.ipynb : figures in the supplemental information. The notebooks read inputs from data/ and write intermediate outputs to results/ . The figures use the Fira Sans font, which the notebooks expect in other/Fira_Sans/ .
