Abstract:
The present invention relates to a tank device for storing hydrogen for an aircraft. The tank device comprises an outer tank (1) and an inner tank (7). The inner tank (7) is held in the outer tank (1). The outer tank (1) is arranged such that the hydrogen with first physical characteristics can be stored. The inner tank (7) is designed such that the hydrogen with second physical characteristics can be stored. The outer tank (1) is connected to the inner tank (7) such that the hydrogen can be fed to the inner tank (7) from the outer tank (1). The inner tank (7) is designed such that the hydrogen with the first physical characteristics can be converted to the hydrogen with second physical characteristics. The inner tank (7) is arranged such that the hydrogen comprising the second physical characteristics can be fed to a consumer.
Abstract:
Disclosed is a gas accumulator comprising an outer and an inner diaphragm (1, 2). The inner diaphragm (2) partly surrounds a variable gas accumulator chamber (20). A diaphragm opening (40) for a device for measuring the fill level (41) of the gas accumulator chamber is provided within the outer diaphragm (1). Said device encompasses a level sensor (42) that is attached to a sensor holder (59) which is connected to the edge of the diaphragm opening (40) by means of a connecting element (56'). The connecting element (56') is formed by a tube (46), an end opening of which is connected to the edge of the diaphragm opening (40). The sensor holder (59) comprising the level sensor (42) is mounted on the other end opening of the tube (46) such that the tube (46) is fastened over the diaphragm opening (40) and the level sensor (42) is thus placed at a distance from the diaphragm opening (40) by using the supporting pressure prevailing between the inner diaphragm (2) and the outer diaphragm (1).
Abstract:
A system and method utilising compressed gas according to which the gas is compressed at a location (10) above ground and transported to an underwater location(16). The gas is stored at the underwater location and later returned from the underwater location to the above-ground location for utilisation as energy.
Abstract:
Gas supply arrangement (1) of a marine vessel (6) being adapted to carry liquefied gas in its cargo tank (4) having an ullage space section (4.1) and a liquid phase section (4.2), which arrangement utilises the gas as fuel to provide power for the vessel, the arrangement comprising a first gas supply line (2) provided for processing the natural boil-off gas formed in the cargo tank, a second gas supply line (3) which connects the cargo tank (4) and the gas main supply line (7) and which is provided with at least a pump (3.1) for raising the pressure of the liquid gas and for pumping it forward. The second gas supply line (3) is provided with a gas reservoir (3.2) having an ullage space section (3.3) and liquid phase section (3.7), and that the arrangement is provided with a first duct section (3.4) of the second gas supply line (3) connecting the liquid phase section of the cargo tank (4) and the liquid phase section of the gas reservoir (3.2), and being provided with the pump (3.1), and that the arrangement is additionally provided with a return line (3.14) connecting the liquid phase section of the reservoir (3.2) and the cargo tank (4) being provided with a control valve (3.15) for controllably returning liquid gas back into the cargo tank (4).
