- hydrogen is provided as the gas.
- This has a particularly high energy content.
- hydrogen is a common technical gas that is used in a variety of ways on construction sites and for which there is also well-established storage and delivery logistics.
- a preferred embodiment of the invention is that the drive is designed as a gas engine or as a fuel cell.
- the drive can in particular be a gas engine, which is driven in a known manner with a gas as fuel, in particular natural gas, liquid gas or a biogas.
- the drive in the sense of the invention can also be designed as a fuel cell, through which the supplied gas, in particular hydrogen, is converted into electrical energy in an electrochemical reaction, which can be used to operate electric motors.
- the method according to the invention is characterized in that in a construction operation, at least one exchange unit is attached to the superstructure, from which gas is supplied to the at least one drive, and that in a ferry operation and / or a construction operation, the at least one exchange unit is removed from the superstructure and Gas from the stationary unit is supplied to the at least one drive.
- the method according to the invention can be carried out in particular with one of the previously described mobile construction machines according to the invention.
- the advantages described above can be achieved.
- a preferred method variant is that gas from the at least one changing unit and the stationary unit is supplied to the drive in a controlled manner via a distribution device.
- a defined gas supply to the drive can take place via a control system, in particular in accordance with a predetermined control program in a construction company. Gas can largely be provided from the connected exchange unit to supply the drive.
- the distribution device can be controlled in such a way that if the container or containers of the stationary unit are empty or partially empty, this or these are filled completely or at least to a minimum level, so that a later ferry operation or other further construction operation of the construction machine can be carried out to a desired extent is ensured even after removing the exchange unit.
