To better illustrate the influence of permeability on energy storage performance, the integrated efficiency and gas recovery ratio averaged over 100 days for the different permeability cases, are calculated and shown in Fig. 4 (c).. With the global energy storage market hitting $33 billion annually and producing nearly 100 gigawatt-hours of electricity [1], understanding permeability (the rate of technology adoption across industries) has become as crucial as the technologies themselves. Imagine trying to charge your EV during. . Relative permeabilities of water and steam were calculated, by applying the Shinohara method, using data from geothermal wells in Iceland. This method does not require that the local water saturation of the two phase mixture is known, but requires production history of mass flow and enthalpy from. [pdf]
When permeability exceeds the critical value, energy storage performance worsens as permeability increases in the flat aquifer. However, when permeability is below the critical value, the energy storage performance remains almost unchanged. Fig. 4. Variation of energy efficiency and gas recovery ratio across different permeability values in CAESA.
An optimal permeability of 100md is identified for achieving the best energy storage performance. With a cyclic rate increase, the performance shows the opposite trends in different permeability regions and the optimum permeability becomes larger.
The optimal permeability varies from 100 md to 300 md with the increasing cyclic rate due to the increasing competitive advantage of the deliverability. A large initial air bubble mass with sufficient air pressure support can improve the energy storage performance across all permeability cases.
The relative permeabilities can be determined in various ways. If the local water saturation in Eq. (5) is known, the relative per-meabilities can be determined using one of the available relative permeability functions, f and g, of the water saturation as shown in Eqs. (8) and (9).
The reason for this difference can be that the relative permeabilities from the experimental data represent two phase flow in porous matrix rather than in fractured material as the relative permeabilities from the field data do.
Relative permeabilities of water and steam were calculated, by applying the Shinohara method, using data from geothermal wells in Iceland. This method does not require that the local water saturation of the two phase mixture is known, but requires production history of mass flow and enthalpy from each well.

Energy storage technologies have the potential to reduce energy waste, ensure reliable energy access, and build a more balanced energy system. Over the last few decades, advancements in efficiency, cost, and capacity have made electrical and mechanical energy storage devices more affordable and accessible.
To meet these gaps and maintain a balance between electricity production and demand, energy storage systems (ESSs) are considered to be the most practical and efficient solutions. ESSs are designed to convert and store electrical energy from various sales and recovery needs [, , ].
