“…Even though encapsulation can help to solve this problem, it is somewhat costly. To address this problem, several studies (Ehid and Fleischer, 2012;Kaygusuz and Sari, 2007;Qu et al 2019) have examined using supporting materials with porous structures such as non-biodegradable high-density polyethylene (HDPE) used to encapsulate paraffin (Kadohiro et al 2021(Kadohiro et al , 2020.…”

Thermal energy storage systems that use composite phase change materials (CPCM), such as paraffin wax and nonbiodegradable high-density polyethylene, are gaining attention in recent years due to the effort to resolve energy issues. There is a need to undertake research and development on how to prepare durable CPCMs from thermo-chemically treated biowastes, a renewable resource. Raw spent coffee grounds (SCG) have been experimented on previously, but more research needs to be conducted on CPCMs prepared from pyrolyzed SCG-biochar (SCGB) for use in a water tank. This research investigated a biodegradable CPCM made from SCGB and carnauba wax in a lab-scale solar water heater system. The carnauba wax loading of 60% was chosen due to the minimized thermal wax leakage from the PCM. Thermal characterization results revealed that the latent heat of SCGB CPCM is 88.47 J/g which was found to be competitive compared to other biodegradable CPCMs reported earlier. The results also show further potential for using SCGB and carnauba wax as a CPCM in a thermal energy storage system.
