This Zenodo record provides the visualization notebook and the result dataset for the year 2050, corresponding to the paper "Exploring Internal and External Drivers of Hydrogen Deployment in the Energy Transition." To ensure manageable file sizes, only key part of the 2050 results are included in this repository. The full dataset (2025–2050, ~350 GB) is available and will be shared upon request. The notebook was used to generate key figures in the main text as well as selected figures in the appendix. The materials are shared to support transparency and partial reproducibility of the published results. We additionally provide supplementary tables reporting the exact annual hydrogen production values for all scenarios and modeled years (one sheet per pathway). These tables support precise inspection of the values underlying Figure 2.
