Wherever traffic cannot be avoided or shifted to climate-friendly modes of transport in the course of the mobility transition, alternative drives and energy sources come into play ("drive transition"). Electric vehicles enable the direct use of renewable electricity in transport with high energy efficiency - in the passenger car sector they have now reached the mass market. But in road freight transport in particular, alternatives to pure battery drive are also being discussed and tested. A power supply for trucks from overhead lines can reduce the need for batteries and thus protect the climate and resources from vehicle production. And "green" hydrogen can be a sensible solution where electricity cannot be used directly, e.g. in long-distance transport and in aircraft.
Important research questions concern the suitability of the different technologies for specific areas of application from a comprehensive practical and environmental point of view.
To this end, the ifeu is investigating the technical, economic and operational challenges of the drive transition as well as the climate balance and other environmental impacts of various technologies over their entire life cycle (Life Cycle Assessment=LCA). Our approach is based on the modelling of the key interdependencies. Due to the rapid development in this field, it is particularly important for the ifeu to always use current and comprehensive data and to constantly question model assumptions. Our work is therefore characterised by close links to field trials as well as to the national and international research community.
