The encapsulation of phase change materials (PCMs) into additive manufactured porous supports is attracting great interest for developing thermal energy storage (TES) with improved performance. Here, highly (86 %) self-supported 3D activated carbon/alumina are fabricated by direct ink writing (DIW) and, then, infiltrated solar salt, a corrosive PCM melting temperature around 220 °C commonly employed in concentrated power plants. This novel, robust, chemically compatible, and lightweight 3DTES exhibits good efficiency (70 stability, high density (381 J g−1), avoids the liquid leakage molten salt. Besides, support promotes better ability to absorb (79 enhances conductivity salt (up 64 %). These results validate use DIW manufacturing innovative TES an enhanced behaviour.

Sisal fiber exhibits a fibrous and porous structure with significant surface roughness, making it highly suitable for storing phase change materials (PCMs). Its intricate morphology further aids in mitigating the risk of PCM leakage. This research successfully employs vacuum adsorption to encapsulate paraffin within sisal fiber, yielding potentially cost-effective, durable, environmentally friendly energy storage medium. A systematic investigation was carried out evaluate effects sisal-to-paraffin mass ratio, length, level, negative pressure duration on loading rate paraffin. The experimental results demonstrate that 8 wt% can be achieved by subjecting 3 mm 16 1 h at -0.1 MPa. Through utilization nano-CT imaging enhancement technology, along petrographic microscopy, this study elucidates mechanism underlying during adsorption. observations reveal substantial portion is primarily stored pores while smaller quantity firmly adsorbed onto its surface, thus durable findings contribute both theoretical foundations available practical guidance fabrication implementation paraffin/sisal composite mediums.
