[57] ABSTRACT
A gas storage system formed of a continuous pipe wound in plural layers, each layer having plural loops. The pipe may be distributed within a container, which may serve as a carousel for winding the pipe and as a gas containment device. When containers, each containing a continuous pipe are stacked upon each other, the weight of upper containers may be born by the walls of lower containers, thus preventing lower layers of pipe from suffering stresses due to crushing by upper layers. A method of transporting gas to a gas distribution facility including obtaining a supply of gas at a gas supply point remote from the gas distribution facility, injecting the gas into a continuous pipe bent to from plural layers, each layer including plural loops of pipe, transporting the continuous pipe along with the gas to the gas distribution facility preferably in a ship and discharging the gas at the gas distribution facility. It is preferred that cooling of the pipe during discharging of the gas be conserved so that during subsequent filling the pipe is initially cool. Also, in a further aspect of the invention, during filling, the gas pressure should be maintained as constant as possible for example by controlled release of an incompressible liquid from the pipe as the pipe is filled with gas. Energy from the incompressible liquid may then be recovered or dissipated outside of the pipes.
