High performance Carnot Batteries based on hybrid cycles
, 2021 Pumped thermal energy storage (PTES) has seen a rapid increase in research interest and private investment during the last few years. A range of different concepts has been proposed, based on different thermodynamic cycles, and the most promising ones are already being turned into demonstration projects or small-scale storage plants. These include PTES

Introduction of a High-Level, Application Based Sizing Methodology for Carnot Batteries
, 2021 Due to the ever increasing share of renewable energy sources (RES) in the energy mix, large-scale energy storage systems are considered essential to ensure the security of supply in energy systems. In recent years, Carnot batteries have been introduced as an alternative grid-scale electrical storage system. In this storage concept, electrical energy is

Energy Technology, Volume 14, Issue 4, April 2026.Heat‐pump charging of Carnot batteries with zeotropic large temperature glide CO2–alkane mixtures enables charging from ambient to ≈398.15 K with improved heat‐exchanger temperature matching at moderate pressure ratios. The highest COP occurs near xCO2 ≈ 0.15, whereas cost and throttling losses rise monotonically with CO2 content; butane isomers ...
