It can be concluded that in the future green EPS water storage as energy storage serves the same objectives as in natural flow of water. Thus, the difference that occurs between the current and future use of water storages is only in the features of " water resources " used for hydroelectric energy production.

The sand battery works on the principle of sensible heat storage, which means that the thermal energy is stored in the form of heat in the sand particles. In a sand battery, sand is heated using renewable energy sources such as wind, solar, or geothermal energy
A storage reservoir almost always contains some water and may have an active water drive. When dry gas from the pipeline is injected into the storage reservoir, liquid water from the formation will evaporate into the injected gas. The gas will then have too much water to be pipeline quality gas. The gas must be dehydrated on the withdrawal cycle.
Therefore, inclusion of reservoir demand and storage characteristics in climate change impact analysis on a catchment may help to improve the understanding of changes in future water availability. This study addresses the climate change impact on demand supply characteristics of a reservoir in a subtropical region of India.

So in general sense, passive gain already meets the load. So the storage only needs to take care of the fluctuation. It''s all about design objective. Say we want enough storage for 10 very cold days with no solar gain, let''s assume avg 0F so deltaT 68F so 6800btu/h, or 2kwh/h, 48kwh/d, 480 kwh for these 10 days. That''s about 1.6mbtu.
