Abstract: The invention relates to a fluid energy machine and a method for generating a fluid-volume flow and for compressing a fluid by means of the fluid energy machine according to the invention. The invention also relates to a method for refuelling a vehicle with a fluid using the method according to the invention for generating a fluid-volume flow and for compressing a fluid, and to the use of a fluid energy machine according to the invention for refuelling a motor vehicle. The fluid energy machine comprises a crank drive (20) and a drive device (10) that is mechanically connected to the crank drive (20), by means of which drive device a torque can be introduced into the crank drive (20), as well as a piston-cylinder unit (30), the piston (32) of which is mechanically connected to the crank drive (20). The drive device (10) comprises two electric motors (50, 60), the respective output members (51, 61) of which are mechanically connected to the crank drive (20).

Abstract: A method for operating a hydrogen fueling station is described, wherein the latter exhibits at least at least one storage tank, which is used to store liquefied hydrogen, and in which boil-off gas at least occasionally accumulates, at least one cryogenic pump, which is used to compress the hydrogen to the desired dispensing pressure, at least one dispenser, through which the compressed hydrogen is dispensed, and lines that connect the aforementioned components. According to the invention, the boil-off gas that accumulates is at least partially used for cooling at least one component and/or line of the hydrogen fueling station and/or is at least partially catalytically combusted.

Abstract: A method for determining a tank pressure in a tank before the tank is filled with pressurised, gaseous hydrogen, according to which method an accumulator, in which the hydrogen to be used to fill the tank is stored as liquid hydrogen, is connected to the tank by means of a filling line and a subsequent check valve of the tank wherein hydrogen is pumped from the accumulator into the filling line by means of a pump and the filling-line pressure arising in the filling line during the pumping is measured, wherein the check valve is opened if the filling-line pressure exceeds the tank pressure, and wherein the tank pressure is determined as the filling-line pressure that exists when the check valve is opened.
