Are polyols a phase change material for thermal energy storage?

Also, the overall thermal energy storage capacity of the PCM (polyols in this case) over the temperature range T1–T2can be determined employing Eq. (13). 3. Polyols as phase change materials for thermal energy storage

What are polyols & how are they made?

Polyols are basically compounds containing multiple reactive hydroxyl groups and one of the major constituting elements in making polyurethane and polyurethane foam. Traditionally, the polyols are obtained from fossil fuels.

Are polyols a PCM for thermal energy storage?

Polyols; of some also known as sugar alcohols, are an emerging PCM category for thermal energy storage (TES). A review on polyols as PCM for TES shows that polyols have phase change temperatures in the range of −15 to 245 °C, and considerable phase change enthalpies of 100–413 kJ/kg.

What is a renewable polyol?

Renewable polyols can be produced from vegetable oil, either edible or nonedible. These mainly consist of triglycerides, with or without an inbuilt hydroxyl group. The hydroxyl group can be induced via different chemical transformations and successfully converted into renewable polyols.

What are some renewable sources for polyols?

This article summarizes the synthesis of renewable polyols and polyurethanes thereof through utilization of various renewable sources such as vegetable oils, lingo-cellulosic biomass and other feedstock.

Are polyols a good material?

In overall polyols are generally an interesting material category even compared to other less expensive organics like paraffins and fatty acids. This is with the advantages of polyols over e.g. paraffins which are of non-renewable origin, and fatty acids which have more metal corrosion attributes.
