sCO2-based thermally integrated-pumped thermal energy storage (TI-PTES) integrating freely available heat sources in both charging and discharging cycles

Year: 2025

Type: article

Abstract: • Two configurations of the discharging cycles have been compared (TES on top and Waste Heat on top), with the second one being more favourable. • Both configurations have been analysed also from a CAPEX point of view with higher CAPEX foreseen for the second configuration. • CAPEX of the proposed system is lower than a traditional TI-PTES due to lower impact ofTES cost. • A sensitivity analysis and then an optimization of the operating pressures of the systems have been performed.
