The promise and challenges of utility-scale compressed air energy storage in aquifers

چکیده
Abstract Widely distributed aquifers have been proposed as effective storage reservoirs for compressed air energy (CAES). This aims to overcome the limitations of geological conditions conventional utility-scale CAES, which has date used caverns reservoirs. As a promising technology, in (CAESA) received increasing attention potential method deal with intermittent nature solar or wind sources. article presents selective review theoretical and numerical modeling studies well field tests, along efficiency economic analyses, assess feasibility emerging technology. Although some tests suggest that large bubble could be created sustain working cycles at target rates, challenges remain before technology can recommended wide deployment. The critical safety factors affecting gas development sustainability operation include structure, aquifer depth, hydrodynamic mechanical properties, such porosity, permeability, compressibility, mineral composition. Moreover, injection/withdrawal configurations oxidation reactions caused by oxygen should also considered. failed attempt renewable combined CAESA Iowa is described lessons learned are summarized. Combining thermal storage, using CO2 cushion gas, horizontal wells hydraulic fracturing, man-made boundaries improve but need further study future applications.

Controllable and affordable utility-scale electricity from intermittent wind resources and compressed air energy storage (CAES)
World wind energy resources are substantial, and in many areas, such as the US and northern Europe, could in theory supply all of the electricity demand. However, the remote or challenging location (i.e. offshore) and especially the intermittent character of the wind resources present formidable barriers to utilization on the scale required by a modern industrial economy. All of these technical...

The use of photovoltaic (PV) cells in domestic and industrial applications has grown rapidly through the recent years. Constructing PV plants is a very smart measure to produce free electricity in large scales, especially in the countries with higher solar irradiation potential. On the other hand, compressed air energy storage (CAES) has already been proposed to be employed for energy storage a...
