Isothermal compressed wind energy storage using abandoned oil/gas wells or coal mines

Wind energy has rapidly increased and is expected to continue to do so over the next few decades. This will exacerbate the issue whereby its intermittent energy production does not generally coincide with energy demand. This can be addressed by integrating cost-effective energy storage with wind farms. The present study develops a concept that leverages the capacity of underground reservoirs of abandoned oil or gas wells to avoid the costs of...
