Data and code for: Thermochemical and hybrid thermal energy storage at low, medium and high temperatures: a critical review from materials to systems

Scripts, derived tables and figure data behind the bibliometric and text-mining analysis of the review "Thermochemical and hybrid thermal energy storage at low, medium and high temperatures: a critical review from materials to systems" by Mirkhon Tokhirov, Quvonchbek Ulugbekov and Khushdil Ahmadov (submitted to the Journal of Energy Storage). Four Scopus queries (2013-2026, last run and exported on 31 October 2026) gave 20,141 unique documents, which were analysed with general bibliometric statistics and TF-IDF + NMF topic models (14 topics for the full corpus, 9 sub-topics for thermochemical storage). The package contains the query strings and settings (Appendix A of the article, and the broadened thermochemical query of the sensitivity analysis), ten analysis scripts (01-09: bibliometric statistics, topic models, dendrogram, the stability test of the topic number K, and three sensitivity analyses of Appendix A.6: multi-label documents and the wording of the hybrid query, presence threshold / K / bootstrap checks, and the broadened thermochemical query) plus the generator of the schematic figure drafts, all derived tables with their summaries and run logs, one script and one CSV for each article figure and for the graphical abstract, and the Scopus EID and DOI of every document. Licensed Scopus record content (titles, abstracts, keywords, author and affiliation data) is not included; README.md explains how to rebuild the corpus.
