Summary

Solar photovoltaic (PV) and wind power, the two most popular renewable energy sources, cause temporal imbalances between energy demand and supply, requiring fossil fuel reserve power or costly electric energy storage to prevent grid blackouts. Alternatively, using heating, ventilating, and airconditioning systems (HVAC) for converting electric energy and storing it in thermal form when the electricity supply is high while the demand is low can change the enduser demand profile, reducing the required reserve power and/or storage. This paper reviews technology for water-based thermal energy storage (TES) for vapor compression systems for heating and air conditioning (AC) applications at the residential scale. Also, we screen the potential of water-based TES in shifting HVAC loads for residential buildings. The presented work informs future research needs by providing an overview of available thermal energy storage options and their applications in residential buildings. In addition, the findings of the preliminary study show the potential of waterbased TES in shifting loads with a reasonable size compared to the building footprint.
