Designing and Demonstrating a System for Efficient and Sustainable Road Freight Based on Dynamic Power Supply

Addressing the constraints faced by road freight of significantly reducing CO₂ emissions, lowering fuel costs and improving air quality, an Electric Road System (ERS) was developed and tested as part of the ENUBA Research Project. The system centers around Catenary-Hybrid heavy-duty vehicles (HDV) and was demonstrated on a dedicated track. The ERS enables the use of renewable electricity and exhibits twice the energy efficiency of conventional diesel HDVs. The technological development was made possible by combining expertise from rail electrification and electric drives systems with a newly developed active pantograph, which dynamically connects to the catenary. Thus it provides continuous supply of electricity to the vehicle’s engine and additionally enables recharging on-board energy storages. The research project demonstrated that a hybrid truck can run in pure electric mode without any changes in driver operation and without any concessions in truck performance. The ERS infrastructure was successfully designed for integration into a highway environment, e.g. adjusting for low clearances and road sign bridges. The result, in operation since 2011, was the first fully operable prototype on a dedicated test track with overhead contact line (OCL) infrastructure. In addition to providing highly promising results in terms of technology, the tests also demonstrate benefits to the environment and economy
