A vehicle is equipped with a hydrogen tank that stores hydrogen, a fuel cell that generates electricity from the hydrogen in the hydrogen tank, a filling device 4 that fills a fuel cell vehicle with the hydrogen stored in the hydrogen tank, and a charger with which electricity generated by the fuel cell is charged to an electric vehicle. Using the vehicle, hydrogen and electricity are delivered to the home of a user.

A control unit for a pressure container system comprising at least one pressure container with a pressure container valve designed to conduct fuel from the pressure container into a removal line for supplying an energy converter. The control unit is designed to determine that a fueling procedure of the pressure container is occurring or has occurred. In response thereto, the control unit is additionally designed to cause the pressure container valve to open in a pulsed manner temporally prior to a removal request for fuel for operating the energy converter so that the pressure in the removal line approximates the pressure in the pressure container.

To provide a safety joint that can prevent an O-ring from falling off due to an ultra-high pressure hydrogen gas flowing through a flow passage in the safety joint at high speed and from being damaged by a foreign matter coming into contact with the O-ring if the foreign matter is mixed in the hydrogen gas.

Heat is transferred from a flow of liquid hydrogen to a flow of a heat transfer fluid at a first heat exchanger to produce a warmed flow of pressurized hydrogen and a cooled flow of heat transfer fluid. Heat is also transferred at a second heat exchanger, to the cooled flow of heat transfer fluid, from a flow of pressurized hydrogen that is derived from one or more buffer vessels filled by the warmed flow of pressurized hydrogen and/or the warmed flow of pressurized hydrogen from the first exchanger to produce a cooled flow of pressurized hydrogen that is used to fill tanks of fuel cell electric vehicles.

Disclosed is a machine learning energy management system that regulates incoming energy sources into compressed air storage operations and energy generation. Compressed air is directed into a thermoregulation system that cycles storage tanks according to physical qualities. A boost impulse creates energy to initiate the electrical energy generation. The compressed air operations and energy generation leverage the heating and cooling of an external HVAC system to improve performance and conservation of the heating and cooling for an external building. The system combines real-time data, historical performance data, algorithm control, variable air pressure for demand-based generation, tank-to-tank thermal cycling, building air heat exchanger, and boost pulsation to achieve optimized system efficiency and responsiveness.

A rare earth regenerator material particle and a regenerator material particle group having a high long-term reliability, and a superconducting magnet, an examination apparatus, a cryopump and the like using the same are provided. A rare earth regenerator material particle contains a rare earth element as a constituent component, and in the particle, a peak indicating a carbon component is detected in a surface region by an X-ray photoelectron spectroscopy analysis.

A motor vehicle with a pressure vessel system includes at least a first pressure vessel arranged in a first region of the motor vehicle and at least one second pressure vessel arranged in a second region of the motor vehicle having a lower intrusion probability than the first region. Fuel is preferentially removed first primarily from the at least one first pressure vessel. When the lower limit of fuel level or fuel temperature is reached in the at least one first pressure vessel, fuel is removed from the at least one second pressure vessel. If the fuel supply rate from the at least one first pressure vessel is lower than an overall fuel supply rate for an energy converter, fuel is removed from the at least one second pressure vessel to meet the overall fuel supply rate needed by the energy converter.
