6 FAQs about [Artificial hole compressed air energy storage]
Which energy storage technologies are most efficient?
Currently, the existing large-scale energy storage technologies include pumped hydro energy storage (PHES), geothermal, hydrogen, and compressed air energy storage (CAES) [, , , , ]. However, only PHES and CAES demonstrate economic efficiency in large-scale, high-power operation conditions.
Does a larger cavern radius reduce air leakage?
However, a larger cavern radius requires higher stability and increases the difficulty of construction. This indicates that a proper selection of cavern radius can reduce the air leakage rate from concrete lining caverns.
How can a cavern reduce air leakage?
The daily air leakage rate can be reduced by modestly increasing the cavern radius, lowering the temperature of the injected air, and decreasing the maximum operating pressure. These results can provide a reference for the study and construction of CAES caverns in similar projects. 1. Introduction
Does concrete lining permeability affect airtightness of CAES caverns?
Hence, the concrete lining permeability is a major factor affecting the airtightness of CAES caverns. To satisfy the sealing requirement, the corresponding concrete permeability should not exceed 1 × 10 −19 m 2 at an operating pressure of 4.5–10 MPa. Fig. 16. Influence of concrete lining permeability on air leakage. 5.3.2.
How long does air seepage last in a concrete lining?
In the first day, the air seepage distance is short that it does not exceed the thickness of the concrete lining. Before the seepage distance reaches 0.5 m, the pore pressure gradient already equals 0 and the air stops seeping. After 20 days of operation, the air seepage distance increases to 5 m.
What happens if air seepage distance exceeds a concrete lining?
When the distance exceeds the thickness of the lining, the variation of pore pressure slows down apparently and finally stabilizes. In the first day, the air seepage distance is short that it does not exceed the thickness of the concrete lining.
