Abstract:
A method for compressing a gas by means of a multi-stage piston compressor is disclosed, wherein, if an inlet pressure of a first compression stage exceeds a threshold value, the gas is at least partially, in particular completely, branched off before the first compression stage and fed to a second compression stage, which directly follows the first compression stage. A computing unit for performing the method to such a multi-stage piston compressor are further disclosed.
Abstract:
A storage device for storing a gas, in particular for storing gaseous hydrogen, having a first chamber for receiving the gas and a locking device for closing and opening a flow path connected to the first chamber. The storage device further has an adjustment unit for volume change of the first chamber. Further there is disclosed a gas storage unit which is the storage device wherein the gas is stored in the first chamber and to a method for the at least partial filling or emptying of the gas storage unit.
