CCUS-Enabled Hydrogen Production Data

Description

# Analysis dataset and sensitivity-analysis outputs **Manuscript:** Project-Level Causal Inference of a Minimum Viable Scale Threshold and Adoption Band in CCUS-Enabled Hydrogen (iScience, 2026) **Authors:** Joseph Junior NKOU NKOU, Dongsheng Cai, Qi Huang, Olusola Bamisile, Chukwuebuka J. Ejiyi, Anto Jonathan Leoba **Licence:** CC BY 4.0 ## Contents - `analysis_set_v2.csv` — Harmonised project-level analysis dataset (n = 2,437). Rows are hydrogen projects; columns include treatment (T_ccus, four-detector OR rule), outcome (log10 installed MWel capacity, with k=0.18 imputation for missing values), and covariates (Technology_agg, Region_policy, Status_clean, year, project-scale category). - `changepoint_*` — Binary-segmentation changepoint analysis outputs. - `placebo_permutation.csv` — 200 random-permutation placebo ATE values. - `region_exclusion.csv` — Leave-one-region-out sensitivity. - `rosenbaum_evalues.csv` — Rosenbaum Γ_critical and E-values per stratum. - `tech_stratified_ate.csv` — Technology-stratified ATE. - `trim_band_sensitivity.csv` — ATE across four propensity-trim bands. - `exposure_detector_distribution.csv`, `exposure_validation_crosstab.csv` — CCUS exposure classification diagnostics. - `summary.json` — Headline numbers reproduced in the manuscript. - `Hydrogen_production_projects_corrected.csv` — User-corrected version of the IEA Hydrogen Production and Infrastructure Projects Database 2025. ## Raw source data (not redistributed here) - IEA Hydrogen Production and Infrastructure Projects Database 2025: https://www.iea.org/data-and-statistics/data-product/hydrogen-production-and-infrastructure-projects-database - IEA CCUS Projects Database 2025: https://www.iea.org/data-and-statistics/data-product/ccus-projects-database ## Code repository All analysis code is at https://github.com/NkJoseph/CCUS-impact-H2-Scalability
