Sodium acetate trihydrate (SAT) has been investigated for many years as heat storage materials but the focus of the investigations were mostly on short-term applications. SAT has a high energy storage density and a large supercooling degree which make it an ideal flexible heat storage. . This paper presents numerical investigations on a heat storage utilizing sodium acetate trihydrate (SAT) as phase change material (PCM). Can. . Sodium acetate, a compound formed by the combination of sodium and acetic acid, has emerged as a promising candidate for innovative renewable energy storage solutions. In addition, in terms of. . In this paper, heterogeneous lyophobic systems (HLSs) have been created by mixing the highly porous zeolite imidazole framework (ZIF-8) with a phase change material (PCM) of sodium acetate trihydrate to enhance the energetic features of the system. This crystalline substance, commonly known as "hot ice," possesses unique thermodynamic properties that make it particularly suitable for. .
