Potential Evaluation of Carnot Battery Integrating Waste Heat Recovery in Industry
36th International Conference on Efficiency, Cost, Optimization, Simulation and Environmental Impact of Energy Systems (ECOS 2023), 2023 One of the keys to the current energy and ecological transition is the development of electrical energy storage. This demand has motivated the development of alternative technologies that overcome some of the shortcomings of the storage systems used until now. Among these, Carnot battery has experienced a rapid development in the last decade.

Advanced Organic Rankine Cycles for thermally integrated Carnot batteries [PDF]
, 2020 Carnot batteries are an emerging technology for base-load capable, electrical energy storage. During charging, the concept converts surplus electrical energy into thermal energy by means of a heat pump. During the discharge phase, a power cycle transforms the stored thermal energy back to electrical energy.

Biomass–solar thermal hybridization using Carnot batteries for s-CO2 Brayton cycles
AIP Conference Proceedings, 2022 Carnot batteries represent state-of-the-art technology in the fields of thermal energy storage and dispatchable electricity generation. The thermal energy usually comes from solar thermal power plants. The present study analyzes and optimizes a hybrid biomass-solar thermal central tower power plant coupled with a carbon dioxide cycle in a supercritical

Stochastically driven single level quantum dot: a nano-scale finite-time thermodynamic machine and its various operational modes [PDF]
, 2012 We describe a single-level quantum dot in contact with two leads as a nanoscale finite-time thermodynamic machine. The dot is driven by an external stochastic force that switches its energy between two values.
