The energy storage medium for aquifer heat energy is natural water found in an underground layer known as an aquifer [9]. This layer is both saturated and permeable. The two steps required to transfer thermal energy are the extraction of groundwater from the aquifer and its subsequent reinjection at a different well nearby, where its temperature has been altered.

Powering Grid Transformation with Storage. Energy storage is changing the way electricity grids operate. Under traditional electricity systems, energy must be used as it is made, requiring generators to manage their output in real-time to match demand. Energy storage is changing that dynamic, allowing electricity to be saved until it is needed

The paper discusses the concept of energy storage, the different technologies for the storage of energy with more emphasis on the storage of secondary forms of energy (electricity and heat) as well as a detailed analysis of various energy storage projects all over the world.
As indicated in the figure, the range of storage can be from capacitors which stores as little of 1 W h of energy for few seconds to chemical compounds which can be used for grid scale storage of several TW h of energy for years. Fig. 2.
As the penetration of renewable resources (e.g. wind and solar) into the grid energy mix continues increase, energy storage is needed to change and optimise the output from renewable sources so as to mitigate rapid and seasonal output changes which occurs as a result of the intermittency in energy supply from aforementioned renewable resources.
TES is one of the most practiced form of energy storage , . TES systems consist of devices which are used to store electricity or other waste heat resources in the form of thermal energy pending the time when they are used to meet energy need.
In a world in full development of technologies related to renewable energies, progress in electrical energy storage systems plays a fundamental role. This development accompanies the promotion of sustainable energy sources and makes it possible to optimize the use of each megawatt generated, contributing to the balance of grid systems.
Another challenge is that of the system economics. The economics of energy storage are difficult to evaluate since they are influenced by a wide range of factors: the type of storage technology, the requirement of each application, size and the system in which the storage facility is located .
