Chinese researchers developed a numerical model showing that a linearly increasing air injection rate improves energy storage efficiency in compressed air energy storage (CAES) caverns from 85.5% to 87.5%, while also identifying wellbore diameter and surrounding rock thermal conductivity as key factors in heat loss.

◆ ◆ The Wire takeaway
You can improve your compressed air energy storage performance by adjusting air injection rates dynamically rather than using a constant flow. Designing your wellbores larger and choosing higher conductivity rock environments could cut heat losses and raise your energy output.
