It covers 304 capacity-and-minimum-load candidates across 42 wind–photovoltaic pairings, together with all 42 complete dispatch schedules for the retained nominal configuration of 900 kW ET-AWE and 100 kW SOWE with a 19% ET-AWE lower operating boundary. Additional materials include parameter-sensitivity results, operating-scenario comparisons, corrected reference-state exergy accounting, and a PEM electrolysis literature-curve comparison and cost benchmark.</p><p dir="ltr">Dynamic HTO is assessed at operating transitions and at 60 s intervals during active oxygen production. The results represent model-based gas-purity feasibility assessments, not experimental plant safety certification. The included MATLAB verification routine checks archived numerical results and reproduces one complete approximately two-year nominal HTO trajectory; it does not regenerate every archived scenario. Full-batch requirements and limitations are documented in the README and reproducibility guide.</p><p dir="ltr">The renewable-generation input derives from the dataset of Chen (2022), Figshare, version 4 (<a href="https://doi.org/10.6084/m9.figshare.17304221.v4" target="_blank">https://doi.org/10.6084/m9.figshare.17304221.v4</a>), released under CC0 and described by Chen and Xu (2022), Scientific Data 9, 577 (<a href="https://doi.org/10.1038/s41597-022-01696-6" target="_blank">https://doi.org/10.1038/s41597-022-01696-6</a>).
