In purely mathematical terms, this means that as things stand, we would need three planet earths to cover humanity’s resource consumption between now and 2050. Since we only have one earth, though, there is no escaping the fact that we will need to utilize renewable resources if we are to stay mobile in the future. Hydrogen will be a fundamental element in tomorrow’s mobility, provided energy from renewable sources is used to produce it. In the vehicle itself, an electrochemical process in the fuel cell will directly convert hydrogen and oxygen from the air into electricity and water. With its low temperature fuel cell stack, characterized by its high power density and dynamism of power delivery, ElringKlinger already possesses the drive technology to facilitate low-emission mobility.
