Abstract: Disclosed are a hydrogen tank and a method of operating the same. The hydrogen tank includes a tank vessel configured with an enclosed interior space for storing an admixture of carbon dioxide and gaseous hydrogen; and a tank port configured to fluidly contact the interior space of the tank vessel and including a semipermeable membrane, which is configured substantially permeable for the gaseous hydrogen and substantially impermeable for the carbon dioxide and is arranged to seal the tank vessel against the outside. The gaseous hydrogen can enter and leave the tank vessel through the tank port via the semipermeable membrane but carbon dioxide is kept in the tank vessel.

Abstract: A method for energy management of a motor vehicle carrying a container powered by an auxiliary power unit is provided. The method comprises determining total energy resources available on the motor vehicle for propulsion of the motor vehicle and for powering the container; determining a first energy fraction of the total energy resources required to power the container with the auxiliary power unit along a route of the motor vehicle; determining a second energy fraction of the total energy resources required to power at least one main motor of the motor vehicle to reach a target destination with the motor vehicle along the route of the motor vehicle; and reallocating at least a fraction of the total energy resources from the auxiliary power unit to the at least one main motor of the motor vehicle or vice versa depending on the first energy fraction and the second energy fraction.
