A novel and improved inventive valve with a regulating function is provided that is capable of filling to higher fill pressures than previously attainable with conventional C-10 on-off valves. The valve contains a single flow passageway by which gas dispenses and enters the valve. A fill adapter is specially configured to engage the valve to allow filling at the higher pressures along the single flow passageway. The structure of the valve allows greater utilization of cylinder capacity; simplifies filling and dispensing with the single flow passageway; and allows for regulating gas pressure during delivery without increasing the overall size of the cylinder package.

A tank for pressurized flammable gas, such as hydrogen, comprising at least one primary cylinder of pressurized flammable gas and at least one secondary cylinder of pressurized extinguishing gas. The at least one primary cylinder is individually equipped with a safety device that is capable of automatically releasing the flammable gas contained in said at least one primary cylinder toward the open air in the event of detection of an overheating situation of the at least one primary cylinder. The at least one secondary cylinder of pressurized extinguishing gas is fluidically connected with each safety device, and the safety device is configured to release extinguishing gas simultaneously with a release of flammable gas.

An energy storage system has a pressure vessel that is exposed to ambient temperatures and that contains a working fluid which is condensable at ambient temperatures (CWF); a liquid reservoir in communication with one of the vessels and containing a liquid that is unvaporizable in the reservoir and in the vessel; and apparatus for delivering the liquid from the reservoir to the vessel. The CWF is compressible within the vessel upon direct contact with the liquid and is storable in a liquid state after being compressed to its saturation pressure. In a method, at least some of the liquid located in the vessel is propelled by the CWF towards a turbine to produce power. In one embodiment, a module has a first vessel having at least four ports, a second vessel at ambient temperatures, and a flow control component operatively connected to a corresponding conduit for selectively controlling fluid flow.
