Project: Stability4TES in BEHeaT program
Dasol Choi is working on the collaboration project of dr.ir. Henk Huinink from TPM group (APSE) and dr. Heiner Friedrich from SPC group (CE&C). The project focuses on investigating salt hydrate-based heat batteries for residential heat supply. The hydration, deliquescence, and dehydration reactions of salt hydrates can store solar-collected heat energy and discharge for space heating/hot water supply. However, the stability of heat batteries is limited for various reasons. In this project, salt-silica composites are investigated to prohibit the salt leakage and achieve longer stability. 

Dasol Choi has a background in Chemical/Environmental Engineering. During his MSc and PhD, he investigated the Calcium Looping process for high-temperature thermochemical energy storage and CO2 capture. Dasol received his PhD in Environmental Engineering from GIST, for his work on proposing the mechanism of the molten salt-promoted carbonation reaction and modified materials to improve the reactivity and stability of the Calcium Looping process.
