The Mercedes-Benz GLC F-CELL (combined hydrogen consumption: 0.34 kg/100 km, combined CO₂ emissions: 0 g/km, combined power consumption: 13.7 kWh/100 km)** ) meets the highest standards with regard to safety, comfort, agility, and design, and was also analysed comprehensively in terms of its environmental impact over the entire lifecycle. When it comes to the overall life cycle assessment, however, the GLC F-CELL benefits from continuous locally emission-free operation and the high efficiency of the electric powertrain.
When it comes to the overall life cycle assessment, however, the GLC F-CELL benefits from continuous locally emission-free operation and the high efficiency of the electric powertrain. For an analysis of the GLC F-CELL’s operating phase, different sources of the necessary hydrogen and the electrical power used for external battery charging were examined.
It is of decisive importance for the CO₂ balance whether the hydrogen for the fuel cell and the power for external charging of the battery are produced from renewable or fossil sources. If the EU electricity mix is used for external battery charging, and the hydrogen is produced from natural gas, the GLC F-CELL emits a total of 34 tonnes of CO₂ over the entire life cycle. If the H₂ Mobility hydrogen mix (50% renewable) is used, the CO₂ emissions can already be reduced by 3.2 tonnes to 30.8 t. The use of power and hydrogen completely generated from renewable resources even makes a reduction to 16 tonnes of CO₂ possible.
In production, the drive components specific to the GLC F-CELL require a greater use of material and energy resources. The proportion of steel and iron is reduced by the omission of a combustion engine and transmission plus their peripheral units. On the other hand, the proportion of polymers, light alloys and other metals is increased. The importance of the production process for the primary energy requirement increases accordingly.
