The review shows that pumped hydro energy storage (PHES) has reached a high maturity level as a technical system and is well covered by economic evaluation methods, whereas solid gravity energy storage (SGES) is still in an initial stage for system design and assessment.
The efficiency of the system is approximately 80% as claimed by developers (Aneke and Wang, 2016). A sketch of this technology is presented in Fig. 1. Gravity energy storage consists of a container filled with a fluid (water) and a heavy piston. The container is linked to a return pipe which allows the flow of water.
Economic analysis is performed. Gravity energy storage delivers a low LCOE. High share of intermittent renewable energy sources disrupts the reliability and the proper operation of the electric grid. Power systems are now on the starting point of a new transformation where high cost requirements have been imposed to secure the supply of energy.

Micro-sized energy storage devices (MESDs) are power sources with small sizes, which generally have two different device architectures: (1) stacked architecture based on thin-film electrodes; (2) in-plane architecture based on micro-scale interdigitated electrodes .
Only three options are available for storing the energy generated: batteries, fuel cells, and supercapacitors (SCs). SCs are now widely regarded as the most effective energy storage device. SCs outperform regular capacitors and secondary lithium-ion batteries [ 21 ].
Summary and prospective Energy stroage microdevices (ESMDs) hold great promise as micro-sized power supplier for miniaturized portable/wearable electronics and IoT related smart devices. To fulfill the ever-increasing energy demands, ESMDs need to store as much energy as possible at fast rates in a given footprint area or volume.
To this end, ingesting sufficient active materials to participate in charge storage without inducing any obvious side effect on electron/ion transport in the device system is yearning and essential, which requires ingenious designs in electrode materials, device configurations and advanced fabrication techniques for the energy storage microdevices.
Fast popularity of smart electronics stimulates the ever-growing demand for micron/nanometer scaled power supplies with simultaneously high energy density and fast power delivery.
