Development of Hybrid PCM-based Thermal Energy Storage Systems

Abstract

The use of phase transition materials for thermal energy storage has been identified as an appropriate option. However, issues arise due to the PCM's low heat conductivity and form stability throughout charging and discharging cycles. We advocate for the creation of hybrid PCM-based thermal energy storage systems in this study. For the proposed study, narrative or reasonably priced biochar-PCM hybrid dormant radiant heat memory content was created and evaluated. Using a batch type pyrolyser, aquatic invasive weed plants are used to create the biochar. Several experimental and analytical techniques have been used to examine the traits and qualities of the innovative energy storage material. Brunauer, Emmett, and Teller (BET), checking electron microscopy (SEM), X-beam powder diffraction (XRD), differential filtering calorimetry (DSC), thermogravimetric investigation (TGA), Fourier-change infrared spectroscopy (FT-IR), and warm conductivity analyzer are a couple of the strategies utilized. The study also suggested the ideal combination of PCM and biofuels by employing hybrid thermal energy storage materials. An novel substance is more stable and thermally conductive than pure PCM because it has a high carbon content and is porous. For the preparation of stable composite materials with good thermal and structural stability, a straightforward impregnation method was used. The best PCM to biochar mixing ratio, with the least amount of PCM leaking out of the composite can be found. When opposed to prior advanced specimens, a sample created using this procedure can exhibit all of the required properties. Because the chemical properties of the composite will be identical to those of the pure PCM, We can prove since no chemical bonding exists in between PCM and the biochar. We are able to determine the heat of fusion using calculations. A PCM's thermal conductivity could be enhanced by employing construct theories based on water hyacinth biochar. The PCM's heat transfer is enhanced even further when flour made of aluminum alloy is added.
