Hydrogen internal combustion engine (H2-ICE) has the potenzial to be an enabler for fast decarbonization in several sectors. In this context, Liebherr is developing a hydrogen combustion engine based on spark ignition. This new powertrain is a part of a strategic approach toward zero emission technologies for off-highway sectors.

    This technology has gained an important interest from the off-highway sector due to several reasons such as:

    Robustness of the technology regarding the duty conditions in the Off-highway sector

    Cost of the power train system

    Quick time to market solution

    Similar installation condition compared to the current powertrain

    Currently, the diesel engine finds its way in a wide range of vehicles in the Off-highway sector and transformation of the current power train to the new zero emission technologies (Hydrogen Engine) will require considering several aspects:

    Investigation and analysis of the current vehicle architecture capabilities

    Development and adaptation of several subcomponents of the powertrain (such as cooling system)

    Modification of the storage system and the fuel path from the tank to the engine fuel interface

    Analysis and installation of the required additional elements regarding the safety precaution

    The development of the technology started with several investigation in the combustion engine test bench; this new power train has been then introduced in vehicle integration and used to build-up a zero emission excavator.

    This paper reviews the current investigations regarding the transformation/adaptation of an excavator powertrain (Diesel-hydraulic excavators) to a hydrogen combustion engine powered machine: Description of the excavator characteristics and analysis of the different characteristics of this new powertrain. Thenceforth, the fuel and storage system is explained and illustrated, followed by a review of several safety precaution aspect. The paper concludes with an evaluation of the new proposed powertrain in terms of dynamic, efficiency and emission. At the end an outlook regarding the further application of the hydrogen combustion engine in different other type of machines in construction and off-highway sector has been given.
