Storage of solar energy is crucial in heating or drying systems when efficient and cost-effective solar energy utilization can be achieved. The great amount of energy demand for drying process can be decreased by the charging of solar energy into Thermal Energy Storage (TES) tank, and the stored energy being used via heat pump
The operation of a thermocline-based storage tank is generally composed of three stages: the charging (energy storage), the stand-by and the discharging (energy release). As for the charging, the hot HTF is introduced into the top port of the storage tank, driving the cold HTF out from the bottom port.

Could a tank of ice or hot water be a battery? Yes! If a battery is a device for storing energy, then storing hot or cold water to power a building''s heating or air-conditioning system is a different type of
Alternatively, single tank configurations (Fig. 1 (b)) can be used to avoid the empty volumes of the two-tank configuration and so reduce the investment costs.This paper focuses on this second type of configurations in which a thermal gradient (thermocline) is maintained within the single tank due to buoyancy effect and thermal stratification, which
Energy storage is the capture of energy produced at one time for use at a later time [1] to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential
In conclusion, the above non-exhaustive list of extensions demonstrates that energy-aware control using energy-tanks is an active research topic.

And, like methane, LNG is odorless, colorless, noncorrosive, and nontoxic. Natural gas is condensed to a liquid by cooling it to about -260°F (-162°C). This process reduces its volume by a factor of more than 600—similar to reducing the natural gas filling a beach ball into liquid filling a ping-pong ball (Figure 3).
