The at least two cryocontainers are connected in hydraulic communication via a cryogenic connecting line, and include a primary storage system having a primary inner tank and a primary outer container, and at least one secondary storage system having a secondary inner tank and a secondary outer container. A heat exchanger is operable to heat the hydrogen, and at least one cryopump is arranged in the primary inner tank to supply unpressurised liquid hydrogen and/or unpressurised gaseous hydrogen in one or more stages at low temperature, to the heat exchanger for delivery to a consumer at a pressure higher than the pressure in the primary inner tank.

A cryostorage system that includes a cryocontainer operable to store liquid hydrogen and/or gaseous hydrogen, the cryocontainer having an inner tank and an outer container, and at least one cryopump, operable to operate at low temperatures, arranged in the inner tank to be fully surrounded, during normal operation, by cryogenic fluid, the cryopump delivering liquid hydrogen and/or gaseous hydrogen in one or more stages to a consumer at a pressure greater than a pressure in the inner tank.

The present application discloses a hydrogen station for supplying hydrogen to a tank of a tank-equipped device. The hydrogen station includes: an integrated controller for integrally controlling devices provided in the hydrogen station; a sensing portion for sensing leaked hydrogen which has leaked inside the integrated controller; a ventilation device performing a high ventilation measure of performing ventilation for air inside the integrated controller or an explosion prevention device performing an internal pressure-based explosion protection measure of creating a pressure-increased state inside the integrated controller; and a compressor unit including a compressor, which is used as one of the devices, and a housing, in which the compressor is stored. The integrated controller is mounted on the housing, and is electrically connected to the compressor via a through-hole formed in the housing to control the compressor.

A gas filling apparatus for filling a plurality of gas storage vessels with a gas, the apparatus comprising a plurality of gas filling ports, each port configured to introduce gas into one of the gas storage vessels, and a controller configured to supply gas to the gas filling ports for filling the vessels and to control the supply of gas to all of the gas filling ports based on a property of any one of the vessels.

Hydrogen storage system (1) comprising a casing (2), a plurality of storage-compression containers (6) forming at least one multi-container unit (4), and a metal hydride (MH) configured for hydrogen storage contained within each of the storage-compression containers, the plurality of storage-compression containers of said at least one multi-container unit being interconnected by gas flow tubes in a direct fluidic connection ensuring that the gas pressure within the containers are substantially the same. The plurality of storage-compression containers are mounted inside a chamber (16) of the casing, the casing configured to sustain a vacuum in said chamber to test leakage of said at least one multi-container unit.

A gas supply system (2) includes a compressor unit (21), an accumulator unit (23), a pre-cooling system (24) and a housing (4). In the gas supply system (2), the compressor unit (21) is vertically arranged and the pre-cooling system (24) is arranged above the accumulator unit (23) in the housing (4). The compressor unit (21) and the accumulator unit (23) are covered by one rectangular parallelepiped housing (4).

Gaseous fueling systems and methods are provided for dispensing fuel to a vehicle or container. The distribution systems speed up the filling process and may eliminate the use of expensive cooling systems required in the art. The methods utilize sequences of filling and emptying the vehicle gas storage tank to control the temperature of the gas inside the tank. The methods repeatedly dispense fuel to the vehicle fuel tank at a first flow rate and for a first period of time and remove fuel from the fuel tank at a second flow rate for a second period to maintain fuel temperature within a desired temperature range and until the vehicle fuel tank is filled to a desired level. In addition, the fill-up mass flowrate can be maximized to system capabilities so a fill-up can be can be completed in about one minute.

Disclosed techniques include energy transfer using high-pressure vessels. Liquid is pumped into a high-pressure vessel to pressurize a gas. The gas can include air. Liquid is sprayed into the high-pressure vessel to cool the gas. Heat exchange is performed to cool the liquid before spraying the liquid into the high-pressure vessel. The spraying liquid into the top and the bottom of the high-pressure vessel is accomplished using nozzles in a top portion and nozzles in a bottom portion of the high-pressure vessel. The pressurized gas is transferred into a storage reservoir. The storage reservoir can include an underground cavern or aquifer. Gas from the storage reservoir is delivered to drive a turbine to recover stored energy. The extracting gas from the storage reservoir is accomplished using an additional high-pressure vessel. Heat exchange is performed to warm the liquid before spraying the liquid into the additional high-pressure vessel.

A ship with a flue gas carbon dioxide capture and storage plant has a main engine such as a slow running diesel engine providing flue gas. The flue gas is led via a flue gas heat exchanger with a thermal fluid exit to a re-boiler and arranged for cooling said flue gas. Further cooled flue gas is led into a turbine compressor compressing it up to a compressed flue gas. A combustion chamber is provided with a fuel feed and a pre-mix gas burner for afterburning said compressed flue gas which also burns remaining methane from the diesel engine, resulting in hot afterburned compressed flue gas enriched in CO.sub.2. The CO2-absorber (20) leading said CO.sub.2-enriched absorber solution to a CO.sub.2-stripper (21), operating at e.g. 1 Bar and exporting CO2 to a CO2-compressor (26) to a CO.sub.2-export line (28) to onboard CO.sub.2 pressure tanks.

A multi-stage compression device, comprising: a first compression stage comprising: two pressure vessels, each being provided with a liquid feeding pipe, via which a working medium A can be introduced into the respective pressure vessel to compress the gaseous medium to a predetermined first pressure P2 by increasing the liquid volume of the working medium A, and the two pressure vessels being able to be supplied with the working medium A by a common liquid pump or two independent liquid pumps, and the working medium A being able to be pumped out of the at least two pressure vessels once the compression process is complete, an intermediate storage tank that is configured to temporarily store the compressed gaseous medium, and a further compression stage which is upstream of the first compression stage and is configured to precompress the supplied gaseous medium.
