Preliminary prospects of a Carnot-battery based on a supercritical CO2 Brayton cycle
Acta Polytechnica, 2021 As a part of the change towards a higher usage of renewable energy sources, which naturally deliver the energy intermittently, the need for energy storage systems is increasing. For the compensation of the disturbance in power production due to inter-day

How the Brain Becomes the Mind: Can Thermodynamics Explain the Emergence and Nature of Emotions?
Entropy, 2022 The neural systems’ electric activities are fundamental for the phenomenology of consciousness. Sensory perception triggers an information/energy exchange with the environment, but the brain’s recurrent activations maintain a resting state with constant ...

What Is Psychological Spin? A Thermodynamic Framework for Emotions and Social Behavior
Psych, 2023 One of the most puzzling questions in neuroscience is the nature of emotions and their role in consciousness. The brain’s significant energy investment in maintaining the resting state indicates its essential role as the ground state of consciousness ...

Achieving Carnot efficiency in a finite-power Brownian Carnot cycle with arbitrary temperature difference [PDF]
Phys. Rev. E 105, 034102 (2022), 2021 Achieving the Carnot efficiency at finite power is a challenging problem in heat engines due to the trade-off relation between efficiency and power that holds for general heat engines. It is pointed out that the Carnot efficiency at finite power may be achievable in the vanishing limit of the relaxation times of a system without breaking the trade-off ...

Thermally driven hydrogen compression using metal hydrides
International Journal of Energy Research, Volume 46, Issue 15, Page 22049-22069, December 2022., 2022 This article overviews R&D activities related to the thermally‐driven hydrogen compression utilising metal hydrides. The focus is put on the interrelation between properties of metal hydride materials and their hydrogen compression performances, first, operating pressure – temperature range, process productivity and efficiency.
