Trolley 2.0 - Trolley Systems for Smart Cities is an Electric Mobility Europe project aiming to prove that battery-supported trolleybuses are a way forward towards electric public transport systems in European cities
Trolley bus systems provide modern zero-emission public transport for urban areas, however, lack the flexibility that battery-equipped electric buses provide. Trolley 2.0 will bring the advantages of both systems together developing trolleybuses further into hybrid-trolleybuses that allow for the partial off-wire operation while making more efficient use of the trolleybus catenaries to charge the batteries in-motion. The 9 Trolley 2.0 partners from public transport, industry and research will aim to prove that battery-supported trolleybuses are a way forward towards electric public transport systems in European cities by demonstrating the new charging concept in-motion charging (IMC), that allows for the partial off-wire operation of hybrid-trolleybuses in remote sections of the networks. The Trolley 2.0 use cases will be located in four cities with existing trolleybus systems from different EU-countries, Szeged (HU), Arnhem (NL), Gdynia (PL) and Eberswalde (DE). These demonstrations will be evaluated and new innovations for smart trolley grids will be demonstrated, e.g. automated wiring technology, smart trolley grid management, the usage of renewable energy sources, energy storage concepts and multi-purpose charging stations based on existing DC infrastructure from trolley networks.
Trolley 2.0 will develop tools, guidelines and recommendations for the design and operation of battery-supported trolleybus services under different context conditions as well as for the development of smart trolley grids becoming a charging backbone for other electric vehicles. Trolley 2.0 solutions will extremely simplify the operation of trolleybuses with in-motion charging and may help to give this well-established technology a new push for both, cities with trolley buses (ca. 350 all over the world) and those without them, as potential recipients for Trolley 2.0 solutions.
Rupprecht Consult will support the global trolleybus association trolley:motion in the management of the project and in the development of business cases and policy recommendations for the further advancement of trolley-hybrid systems.
