Solid-phase cold energy storage represents a scalable approach to thermal energy management, characterized by its suitability for deep low temperature applications, along with advantages related to safety, environmental sustainability, and cost-effectiveness. This technology finds extensive application in large-scale cryogenic systems, such as liquid air energy storage. The thermodynamic...
Space cryocoolers are required to cool sensitive instruments such as infrared detectors and superconducting devices to cryogenic temperatures. Recent advancements have focused on optimizing the performance and reliability of Stirling pulse tube cryocoolers (SPTCs), a hybrid design combining high efficiency and low vibration. This study explores the integration of machine learning (ML)...
This study aimed to evaluate and compare the performance of lithium-ion cells under normal and cryogenic conditions by testing battery cells in accordance with IEC standard 62660-1:2018. The experiments were conducted using SAMSUNG (CR18650Z/M lithium-ion cells) under two test conditions: normal conditions and cryogenic soaking (30 and 60 minutes). Data were collected before and after soaking...
With the growing demand for green energy, hydrogen (H2) and liquid hydrogen (LH2) are gaining attention from the industry and research. A critical challenge arises in the supply of LH2, as industrial gas suppliers typically do not deliver small quantities. Consequently, several cubic metres of LH2 must be bought and stored even for small-scale tests. A need for small scale liquefiers with...
