20 degree organic phase change energy storage

Are phase change materials suitable for thermal energy storage?

Phase change materials (PCMs) having a large latent heat during solid-liquid phase transition are promising for thermal energy storage applications. However, the relatively low thermal conductivity of the majority of promising PCMs (<10 W/ (m ⋅ K)) limits the power density and overall storage efficiency.

Are fatty alcohols a promising organic phase change material for thermal energy storage?

Scientific Reports 10, Article number: 9168 (2020) Cite this article Fatty alcohols have been identified as promising organic phase change materials (PCMs) for thermal energy storage, because of their suitable temperature range, nontoxicity and can be obtained from both natural and synthetic sources.

What types of organic phase change materials exhibit large latent heat and solid-liquid transitions?

Organic phase-change materials, such as low-cost paraffin waxes 8, fatty acids 9, 10, polyethylene glycols 11, and sugar alcohols 12, generally exhibit large latent heat and solid–liquid phase transitions, covering a wide range of melting and crystallization points 13.

Are dicarboxylic acids a phase change material for thermal energy storage?

J. Chem. Eng. Data 2015, 60, 202–212. [ Google Scholar] [ CrossRef] Aydin, A.A. Diesters of high-chain dicarboxylic acids with 1-tetradecanol as novel organic phase change materials for thermal energy storage.

Are solid–liquid phase-change materials effective for melting latent heat?

Among the many thermal energy storage methods, solid–liquid phase-change materials (PCMs) for melting latent heat are an effective method and have received extensive attention because of their high heat storage density and temperature fluctuation, which is far less than the detectable option [ 2, 3, 4 ].

Can photo-switching dopants and organic phase-change materials create an activation energy barrier?

Herein, we report a combination of photo-switching dopants and organic phase-change materials as a way to introduce an activation energy barrier for phase-change materials solidification and to conserve thermal energy in the materials, allowing them to be triggered optically to release their stored latent heat.
