| Abstract Scope |
In thermal energy storage technology, carbon has many uses and potential. To improve thermal conductivity and keep important features like high latent heat, low supercooling value, and high thermal stability and conductivity, various forms of carbon have been used as support materials for thermal energy storage systems in this study. The research explored both commercial and natural sources of carbon for solar thermal energy storage. Carbon compounds from biomass, such as natural bituminous carbon (NBC), jute stick-derived activated carbon (JSAC), and standard commercially available CNT, graphite and graphene, have been examined as carriers. NBC, with its rigid pore structure and large surface area, is particularly effective for storing energy with polyethylene glycol-6000 (PEG) compared to other tested carbon materials. In real conditions, NBC's porous structure can help address leakage issues. The NBC/PEG combination stays stable during thermal cycling, increases latent heat, reduces supercooling value, and improves solar energy conversion efficiencies. |
