Seasonal thermal energy storage with aqueous sodium hydroxide ‒ experimental assessments of the heat and mass exchanger unit

Closed sorption heat storage based on water vapor sorption in aqueous sodium hydroxide (NaOH-H₂O) solution theoretically allows to reach a significantly higher volumetric energy density compared to sensible thermal storage systems. In the present work, the heat and mass exchangers of an absorption/desorption concept will be highlighted and investigated, focusing on the experimental assessment.
