Abstract
Disclosed herein is a system for storing gas at almost constant pressure, which involves the injection and withdrawal of a liquid in a process known as hydraulic compensation. This disclosure teaches a way to minimize that dissolution by ensuring that, as the gas containment is charged up, the hydraulic compensation liquid emerges from the containment at the gas storage pressure and the pressure of that liquid is caused to fall in a number of discrete steps with settling volumes present at the nodes between these steps. These settling volumes enable some gas to come out of solution at each node having lost relatively small amounts of pressure. The gas is compressed back up to storage pressure and re-injected into the main storage containment without significant use of energy.
