Abstract: A gas storage tank (1) has a high pressure resistant shell (10) and a fluid control system (5). The fluid control system (5) has an inlet fluid branch (20) and an outlet fluid branch (30). The inlet fluid branch (20) comprises a check valve (21) and the outlet fluid branch (30) comprises a pressure regulator (32) and a pressure assisted check valve (31). Preferably, the fluid control system (5) also comprises an inlet filter, an outlet filter and flow restriction. The fluid control system (5) is preferably situated entirely on the inside of the high pressure resistant shell (10). The fluid control system (5) is preferably provided as a miniaturized system realized in a stack of bonded wafers, where part devices are formed by micromachined geometrical structures. A method for gas handling with the gas storage tank (1) and a manufacturing method for the gas storage tank (1) are also presented.

Abstract: A gas storage system includes a tank, having a tank gas outlet, and a multitude of gas emitting entities encapsulated by the tank. The gas emitting entities are arranged for providing a gas volume, which when released from the gas emitting entities, is considerably larger than a volume of the gas emitting entities themselves. The gas emitting entities are freely contained in the tank. There are no gas conduits or electrical connections to the tank which has a sealable opening suitable for removal or insertion of the gas emitting entities. The latter have a respective gas release device, which is operable as a response on a stimulation signal. A volume surrounding the gas emitting entities inside the tank is the sole fluid connection between an opening of the gas release device and the tank gas outlet. Methods for storing and releasing gas are also presented.

Abstract: A gas storage system (1) comprises a tank (10), having a tank gas outlet (28), and a multitude of gas emitting entities (20) encapsulated by the tank (10). The gas emitting entities (20) are arranged for providing a gas volume, which when released from said gas emitting entities, is considerably larger than a volume of the gas emitting entities (20) themselves. The gas emitting entities (20) are freely contained in the tank (10), i.e. there are no gas conduits or electrical connections to the tank (10). The tank (10) has a sealable opening (18) suitable for removal or insertion of the gas emitting entities (20) and the gas emitting entities (20) have a respective gas release device, which is operable as a response on a stimulation signal. A volume (14) surrounding the gas emitting entities (20) inside the tank (10) is the sole fluid connection between an opening of the gas release device and the tank gas outlet (28). Methods for storing and releasing gas are also presented.
