Chemical storage fluids, such as hydrogen or methanol, enable energy storage in chemical bonds, which can be converted back into energy when required. The selection of a fluid typically depends on factors such as efficiency, scalability, cost, and the specific energy requirements of the system.
For a storage fluid which is thermally stratified with a linear temperature profile in the vertical direction, the energy content can be shown with Eqs.

PTES with liquid storage transfers large quantities of energy through heat exchangers. Costs and efficiencies are improved by using a working fluid with a high heat transfer coefficient, and previous work has suggested the use of nitrogen, helium, and hydrogen ( Farrés-Antúnez, 2018 ).
Hence, at storage temperature 408.15 K, the recommended pure working fluid pairs listed in order of balanced thermo-economic performance are [Pentane-R123], [Pentane-R1336mzz (Z)], [R1336mzz (Z)-R123], and [R1336mzz (Z)-R1336mzz (Z)] respectively.
Working fluid pair recommendations including pure and zeotropic fluids are offered. Global issues such as the energy crisis and carbon emissions impulse the development of waste heat recovery and energy storage technologies.
