6 FAQs about [Compressed air energy storage rock drilling]
What is compressed air energy storage (CAES)?
Compressed air energy storage (CAES) is an effective solution for balancing this mismatch and therefore is suitable for use in future electrical systems to achieve a high penetration of renewable energy generation.
Which geological Site is suitable for compressed air energy storage?
A suitable geological site for compressed air energy storage is given by a highly permeable porous formation and a tight cap rock to prevent the buoyant rise of the air (see Fig. 1). In northern Germany, anticline structures suitable for CAES can be found in a variety of settings (Baldschuhn et al. 2001).
Should compressed air be injected into a depleted oil & gas reservoir?
However, care is required to inject compressed air into depleted oil and gas reservoirs due to the potential for a combustible environment at the surface or in the subsurface (Kim et al., 2023). CAES also offers extended energy storage durations, enabling the storage of electricity for prolonged periods.
How was compressed air extracted from a well without refilling the air?
First, without refilling the air, the compressed air was continuously extracted from the reservoir by maintaining an extraction air mass flow rate, i.e. gas production rate (GPR), of 417 kg s −1 and a well BHP of 47 bar.
How is compressed air released during discharging?
During discharging, air is released, either heated by burning fuel or stored thermal energy to generate electricity , . Compressed air is stored in underground caverns or up ground vessels , . The CAES technology has existed for more than four decades.
Are compressed air energy storage power plants an option for grid integration?
