LCOH Hybrid Model: Capacity-Weighted Blended Levelized Cost of Hydrogen — Derivation, Sensitivity Analysis, and Cost Tier Reference (PEM + Al–Water, 70:30 Split)

Transparent computation of the capacity-weighted blended LCOH for a hypothetical hybrid PEM electrolysis + Al–water thermochemical hydrogen production system (70:30 baseload:peak-shaving split). Contains: base case inputs and sources, step-by-step equations, full sensitivity analysis (±30% Al scrap price, ±25% solar LCOE, 60:40 and 80:20 capacity splits), robustness summary, and five-pathway cost tier reference. IMPORTANT: All values are model-based projections derived from separately published cost ranges; they have NOT been validated against integrated pilot-scale systems.本数据集针对一套假设的质子交换膜（Proton Exchange Membrane, PEM）电解制氢与铝水热化学制氢混合系统（基荷与调峰容量分配比为70:30），实现了容量加权混合平准化氢能成本（Levelized Cost of Hydrogen, LCOH）的透明化计算。数据集包含以下内容：基准情景输入参数及来源、分步推导公式、完整敏感性分析（涵盖±30%铝废料价格波动、±25%太阳能平准化度电成本（Levelized Cost of Electricity, LCOE）波动，以及60:40、80:20两种容量分配比）、稳健性总结，以及五类路径成本层级参考。重要提示：所有数值均为基于已公开独立发布的成本范围生成的模型预测值，尚未通过集成式中试规模系统完成验证。
