Topic description

Expected Outcome: Project results are expected to contribute to all of the following expected outcomes: Integration of the results of the demonstrations in regular operation of passenger transport operators, in long distance operations. Accelerated replication of this integration, beyond original demo partners, using specific recommendations and sharing of best practices Reliable operation of long distance zero emission buses and coaches in the EU. Improved comfort and inter-modality for long distance people mobility services. Demonstrated innovative zero emission solutions for long distance people mobility in a holistic approach taking net congestions challenges and charging solutions into account. Scope: Zero emission buses for urban and sub-urban use are successfully implemented in Europe. This has addressed the need to improve air quality, reduce noise and innovate people mobility. Yet there are limitations due to range, vehicle weight and available charging infrastructure to further extend zero emission vehicles in more energy demanding long-distance (ranging from regional, national to transnational) people mobility that needs to be addressed. There is a need to further develop zero-emission solutions where vehicle weight and energy demand are challenges. Proposed actions are expected to address all of the following aspects: Develop sustainable and affordable, long-distance zero emission people mobility solutions for different areas and regions with new and viable business cases based on new operation models and smart management of fleets and of coaches and buses. Test and apply concepts, tools and models with direct involvement of European bus/coach providers and operators to speed up deployment. Include the transition from long-distance to urban, in intermodal hubs and with park-and ride. Demonstrate using at least 5 coaches and buses in several operational routes in the EU and/or in corridors segments in different Member States and/or Associated Countries, focussing on long-distance operation patterns (average ≥500 km in extra-urban scenarios, in one or more routing). Demonstrations must cover aspects such as planning, optimised charging/refuelling schedules, passenger experience, driving time regulations, cross-border trips, charging solutions and impacts on the grid. Replication, recommendations and sharing of best practices shall be part of the demonstrations, as well as the development of new business models and the analysis of remaining legal barriers. Develop shared charging solutions that can be used for multiple operators and other vehicle types. Both technical and operational issues must be addressed, as well as “rush hour” at charging stations, balancing demand and supply of energy. The use of charging solutions and shared charging hubs by a variety of mobility and transport operators must be explored, also incorporating seasonal effects and operational demands. Based on user needs, develop flexibility in interior design to enhance travel comfort, safety and user experience, thus aiming at making it more appealing and inclusive to use this mode of transport. Leverage on other 2Zero projects related to Buses and HDV should be considered. [1] This topic implements the co-programmed European Partnership on ‘Towards zero emission road transport’ (2ZERO). As such, projects resulting from this topic will be expected to report on the results to the European Partnership ‘Towards zero emission road transport’ (2ZERO) in support of the monitoring of its KPIs. null Activities are expected to achieve TRL 7-8 by the end of the project – see General Annex B. Activities may start at any TRL. [1] Ref Examples are projects funded under CL5-2022-D5-01-10 and CL5-2022-D5-01-08

Destination

This Destination addresses activities that improve the climate and environmental footprint, as well as competitiveness, of different transport modes. The areas of rail and air traffic management will be addressed through dedicated Institutional European Partnerships and are therefore not included in this document. This Destination contributes directly to the Strategic Plan’s Key Strategic Orientations ‘ Green transition ’, ‘ Digital transition ’ and ‘ A more resilient, competitive, inclusive and democratic Europe ’. In line with the Strategic Plan, the overall expected impact of this Destination is to contribute to the ‘Achieving sustainable and competitive transport modes’ . The main impacts to be generated by topics under this Destination are: Zero-emission road transport Accelerated uptake of a zero-tailpipe emission ecosystem, with interoperable technological solutions developed at system level (vehicles, infrastructure, user and energy grid) that support the global competitiveness of the EU transport and mobility system. Zero-tailpipe emission mobility solutions developed that are affordable, efficient, user-friendly, inclusive, safe and circular with concepts and technologies that are easy to deploy, considering needs, behaviours and socio-economic conditions of all end-users. Clean mobility solutions for a climate neutral and environmentally friendly and zero pollution mobility with a higher level of circularity; Increased responsiveness of zero tailpipe emission vehicles and systems to diverse societal interests and concerns. Aviation Enable breakthrough technologies and innovations that will contribute to the design (addressing also eco-design and circularity principles), manufacturing, maintenance and operations of new generation aircrafts, also powered by renewable energy and sustainable aviation fuels, for a competitive and clean EU aviation ecosystem (including airports). Derisk and accelerate the introduction of new digital technologies (with emphasis on AI) at all levels in the industrial aviation ecosystem, while addressing all safety-related issues in collaboration with the European Union Aviation Safety Agency (EASA). Waterborne transport Higher autonomy range in electric and hybrid vessels. Uptake of renewable and low carbon fuels and improved knowledge on the suitability of innovative renewable and low carbon fuels and other energy carriers for waterborne transport.
