Is sodium acetate trihydrate a heat storage material?

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 material.

Can sodium acetate be used for thermochemical energy storage?

Summarising, this study highlights the potential use of sodium acetate for thermochemical energy storage in heating applications. The studied system presents low hydration and dehydration temperatures adequate for heating applications, and with power density values nearly two orders of magnitude higher than the previously reported for other salts.

Does sodium acetate support heating decarbonisation?

Conclusions This study experimentally analyses the promising supercooled liquid based on sodium acetate (SA) for long-term heat storage to support heating decarbonisation.

Is a thermochemical energy storage system based on sodium acetate hydrate feasible?

A thermochemical energy storage system based on sodium acetate hydrate is feasible. The system can be charged at nearly room temperature in air. The system exhibits stable multicyclic conversion. Attained power densities are one order of magnitude higher than other salt hydrates.

What is sodium acetate aqueous solution?

This research critically analyses the physic and chemistry of sodium acetate (SA, NaCH3COO) aqueous solution, a low-cost, non-toxic, and abundant compound with stable supercooling for long-term heat storage.

Is sodium acetate a sacrificial material for sodium ion batteries?

Sodium Acetate as Residual-Free Presodiation Additive for Enhancing the Energy Density of Sodium-Ion Batteries Sodium-ion batteries (SIBs) suffer from undesirable initial Coulombic efficiency caused by irreversible sodium loss at the anode. Here, we utilized sodium acetate (NaAc) as a sacrificial material to provide extra sodium.
