Research data and code for demand-led mine-water heat-pump hub screening in England

This record contains the article-aligned research data, Python code, model outputs, validation reports and publication figures supporting the study entitled “Demand-led screening of mine-water heat-pump hubs for district heating: A multi-city techno-economic and multi-objective assessment in England”. The archive implements a demand-led screening framework for ten English city groups. The July 2024 mine-water opportunity baseline and mine-water temperature data were linked to residential heat demand through candidate hubs and 1, 2, 3 and 5 km service radii. The workflow includes half-hourly thermohydraulic calculations, comparative levelised-cost-of-heat and operational-carbon assessments for mine-water heat networks, individual air-source heat pumps and gas boilers, exhaustive Pareto analysis and cross-scenario robust selection. The released dataset contains 3,062 candidate hubs, 11,427 eligible hub-radius designs and 34,281 design-scenario records. It reproduces all seven publication figures in vector PDF and 600-dpi PNG and TIFF formats. The accompanying scripts, configuration files, machine-readable tables, validation reports and SHA-256 manifest support transparent reproduction of the retained analyses. The outputs represent planning-screening and investigation priorities. They do not verify sustainable mine-water yield, hydraulic connectivity, water chemistry, thermal breakthrough or an engineered district-heating network.
