with Special Reference to Renewable Energy Sources Compressed air energy storage (CAES) is known to have strong potential to deliver high performance energy storage at large scales for relatively low costs compared with any other solution.
By then the patent application “Means for Storing Fluids for Power Generation” was submitted by F.W. Gay to the US Patent Office . However, until the late 1960s the development of compressed air energy storage (CAES) was pursued neither in science nor in industry.
Note that this value is independent of pressure. Comparing this quantity of energy with the values in Table 6.3 shows that the energy density is quite good relative to the energy stored in the compressed air itself for all realistic storage pressures.
In comparison to electricity, gas and heat, its power density is lower and transportation losses are higher, which can be considered the main reason for this situation. Nevertheless, compressed air has been and still is applied as a storage medium for electrical energy at utility scale.
The simplest way to reuse the temperature related part of the exergy of the compressed air is to store the hot air itself inside a combined thermal energy and compressed air storage volume (Fig. 18a). Due to the high temperatures already reached at rather low pressure ratios these concepts require highly temperature resistant storage volumes.
Evidently, compressed air stored in tanks delivers an energy density that is lower than that of present-day batteries—but not an order of magnitude lower. Based on a present-day (2021) rough assessment of a typical cost of battery-based energy storage at $150/ (kW h), this energy store might justify spending ∼$3600.
