Data underlying the research on: forecast CAPEX and deployment of electrolysers (AEC & PEM)

This dataset contains historical CAPEX data and deployment data for AEC and PEM electrolysers, which support research on probabilistic forecasting of future electrolyser costs and global capacity expansion. The CAPEX data are sourced from Glenk & Reichelstein (2019), while the deployment data are obtained from the IEA Hydrogen Production and Infrastructure Projects Database (2024). The data were collected from peer-reviewed publications and authoritative international databases, harmonised, and adjusted for inflation where needed. Together, they form the empirical basis for modeling deployment trajectories using logistic S-curves and estimating cost trends with Wright’s Law, providing essential inputs for robust, uncertainty-aware techno-economic analysis.

本数据集收录碱性电解槽（Alkaline Electrolyser, AEC）与质子交换膜电解槽（Proton Exchange Membrane Electrolyser, PEM）的历史资本支出（Capital Expenditure, CAPEX）数据及部署数据，可为电解槽未来成本概率预测与全球产能扩张相关研究提供支撑。其中资本支出数据源自Glenk与Reichelstein（2019）的研究成果，部署数据则来自国际能源署（International Energy Agency, IEA）《氢能生产与基础设施项目数据库》（2024）。所有数据均来源于同行评议出版物及权威国际数据库，经过统一标准化处理，并根据实际需要进行了通胀调整。上述数据共同构成了两大研究方向的实证基础：一是采用逻辑斯蒂S曲线对电解槽部署轨迹进行建模，二是借助莱特定律（Wright's Law）估算成本变化趋势，可为开展稳健且兼顾不确定性的技术经济分析提供核心输入参数。
