Data and Scripts for: Techno-Economic Analysis of Hydrocarbon-CO2 Binary Mixtures in Heat Pump-Based Thermal Energy Storages

The data and python scripts used in the Paper Techno-Economic Analysis of Hydrocarbon-CO2 Binary Mixtures in Heat Pump-Based Thermal Energy Storages published in Energy Technology, Volume 14, Issue 4, Apr 2026, https://doi.org/10.1002/ente.202502620 is provided here. These are data for heat pump simulations with zeotropic mixtures, which are coupled to thermal energy storages, as used in Carnot batteries. Butane, isobutane, pentane, and isopentane mixtures with CO2 are investigated as working fluids. In addition investment costs and levelized costs of heat are analyzed and their global sensitivity and uncertainty is estimated.
