“…An excellent comprehensive summary and review of CAES with emphasis on its importance for wind energy was written by Succar and Williams (2008). Many of the recent publications on CAES focus on its contributions to the grid from an energy analysis perspective that assumes CAES is a developed and available storage technology (e.g., Denholm and Sioshansi 2009), while other research is taking a much more detailed look at the physics of CAES (e.g., Raju and Khaitan 2012;Kushnir et al 2012). Other recent work on detailed process modeling is being carried out for lined rock caverns Kim et al 2012).…”

TitlePorous media compressed air energy storage (PM-CAES): Theory and simulation of the coupled wellbore-reservoir system AbstractExpansion in the supply of intermittent renewable energy sources on the electricity grid can potentially benefit from implementation of large-scale compressed air energy storage in porous media systems (PM-CAES) such as aquifers and depleted hydrocarbon reservoirs. Despite a large government research program 30 years ago that included a test of air injection and production in an aquifer, and an abundance of literature on CAES mostly relevant to caverns, there remain fundamental questions about the hydrologic and energetic performance of PM-CAES. We have developed rigorous simulation capabilities for PM-CAES that include modeling the coupled wellbore-reservoir system. Through consideration of a prototypical PM-CAES wellbore-reservoir system representing a depleted hydrocarbon reservoir, we have simulated 100 daily cycles of PM-CAES. We find that (1) PM-CAES can store energy but that pervasive pressure gradients in PM-CAES result in spatially variable energy storage density in the reservoir, (2) the wellbore-reservoir storage component of PM-CAES is very efficient, (3) cap-rock and hydrologic seals along with proper sizing of the PM-CAES reservoir prevent excess pressure diffusion from being a problem, and (4) injection and production of air does not significantly mobilize residual liquid water in the reservoir.2

“…However, the simulation assumed that the rock temperature was constant and did not consider gas seepage into rock mass so as to restrict the application of the result. Kushnir et al [32] studied parameters that affected the temperature and pressure fluctuations and the volume of gas storage. The heat transfer between the rock and air reduced the pressure and temperature fluctuations during the process of air compressing and releasing and increased effective energy storage capacity.…”

A coupled nonisothermal gas flow and geomechanical numerical modeling is conducted to study the influence of fractures (joints) on the complex thermohydromechanical (THM) performance of underground compressed air energy storage (CAES) in hard rock caverns. The air-filled chamber is modeled as porous media with high porosity, high permeability, and high thermal conductivity. The present analysis focuses on the CAES in hard rock caverns at relatively shallow depth, that is, ≤100 m, and the pressure in carven is significantly higher than ambient pore pressure. The influence of one discrete crack and multiple crackson energy loss analysis of cavern in hard rock media are carried out. Two conditions are considered during each storage and release cycle, namely, gas injection and production mass being equal and additional gas injection supplemented after each cycle. The influence of the crack location, the crack length, and the crack open width on the energy loss is studied.

With the blossoming of intermittent energy, compressed air energy storage (CAES) has attracted much attention as a potential largescale energy storage technology. Compared with caverns as storage vessels, compressed air energy storage in aquifers (CAESA) has the advantages of wide availability and lower costs. The wellbore can play an important role as the energy transfer mechanism between the surroundings and the air in CAESA system. In this paper, we investigated the influences of the well screen length on CAESA system performance using an integrated wellbore-reservoir simulator (T2WELL/EOS3). The results showed that the well screen length can affect the distribution of the initial gas bubble and that a system with a fully penetrating wellbore can obtain acceptably stable pressurized air and better energy efficiencies. Subsequently, we investigated the impact of the energy storage scale and the target aquifer depth on the performance of a CAESA system using a fully penetrating wellbore. The simulation results demonstrated that larger energy storage scales exhibit better performances of CAESA systems. In addition, deeper target aquifer systems, which could decrease the energy loss by larger storage density and higher temperature in surrounding formation, can obtain better energy efficiencies.
