IMHO this text cries for rewording in English. The concept of adding energy to the gas so it will flow faster and in larger volume, along with the mechanistic cause-and-effect logic, is foreign to how the situation is normally understood in English, even if it corresponds to a certain way of viewing the process in terms of physics (compression imparts potential energy to the gas, which is transformed into kinetic energy when the gas flows).

'Antriebsenergie' is one of those abstract coinages that German excels in, but which IMO is a misnomer: in terms of garden-variety physics, propulsion arises from force, not energy, although energy is expended in the propulsion of an object.

My suggestion:
The gas is pressurised in compressor stations so it can flow through the pipeline with sufficient speed and in sufficient volume.
