Abstract:
1. A method for the production of gas and self-regulation thereof, comprising submerging a reservoir that includes a charge of solid into a liquid capable of producing gas by reaction with the charge of solid, wherein the charge of solid is in a form of at least one selected from pellets, foam, and powder, the charge of solid is horizontally arranged inside the reservoir above a buffer space free of the charge of solid, the charge of solid extends over the full cross-section of the reservoir such that it obstructs the full cross-section of the reservoir, the charge of solid is permeable to the liquid and the gas, the reservoir includes at least one opening allowing the liquid to flow into the buffer space, and the reservoir includes at least one orifice for discharging the gas; allowing the liquid to flow into the buffer space through the opening of the reservoir and rise into the reservoir while initial gas in the reservoir is discharged through the orifice; and allowing the gas to be generated as the liquid contacts the charge of solid, the generated gas rising through the charge of solid to be discharged through the orifice, wherein the level of the liquid in the reservoir is self-controlled as a function of the difference between the volume of the gas generated and the volume of the gas discharged; wherein the charge of solid includes a metal hydride, and hydrogen is generated when the charge of solid contacts with the liquid; wherein the reservoir further comprises a top chamber in an upper part of the reservoir, the top chamber including the charge of solid and the at least one orifice, and a bottom chamber in a lower part of the reservoir, the bottom chamber being defined by a movable wall, the bottom chamber including the at least one opening allowing the liquid to flow into the reservoir, the bottom chamber being retracted prior to the submerging.
