move2ze­ro

In the “move2zero” project, an integrated concept for the complete decarbonisation of the municipal bus transport system in Graz is being developed.

The goal is an emission-free operation, from the provision of energy and the infrastructure to the vehicles. Attention is paid to low emission factors and high re-use and recyclability of all components.

“move2zero”: Innovative funding project for the decarbonisation of the Graz buses

 

As a lead project, move2zero develops a comprehensive execution and implementation project for the full decarbonisation of a municipal bus system which in future can be transferred to many other municipal transport systems. Based on multi-disciplinary research (which also includes industrial research) and a comprehensive demonstration phase, move2zero will pave the way towards an efficient and effective changeover of municipal public transport systems in the direction of an emission-free future!

To reduce the overall environmental impact, attention is paid in move2zero to the use of components with very low environmental effects and the entire life cycle of vehicles and infrastructure is analysed. For that, as an accompaniment to all research and demonstration initiatives in the project, a comprehensive eco design and life cycle assessment will be carried out.

Demonstration operations:

In a first demonstration operation, 7 battery-driven buses on Line 40 and 7 fuel cell buses on Line 66 will be used in order to collect experiences with different technologies in real-time operation.

In the demonstration operation, the required charging infrastructure to provide energy for the battery-powered buses will be set up and operated depending on the choice of technology along the bus line and/or in the bus centre in Kärtnerstraße. The setting up of a fuelling station in the bus centre is planned for the fuelling of the fuel cell buses. In a first step, the “green” hydrogen will come from an electrolysis plant in Gabersdorf, where hydrogen is produced from renewable energies.

For the selection of an optimum technology mix for the full decarbonisation of the bus fleet, the demonstration operation will be accompanied by research papers from several scientific partners. There will be a targeted monitoring, data analysis and mathematical modelling. Depending on the technology decision for the entire fleet, recharging infrastructure suitable in the long term or a correspondingly higher H2 fuel station plus electrolysis will be constructed and operated to produce the hydrogen in Graz. In the course of the entire project and also in the future, an electricity and hydrogen supply from 100% renewable sources of energy is to be ensured.

In order to achieve a production of hydrogen that is as efficient as possible, i.e. to avoid the loss of efficiency with conventional mechanical compression, there will be research on electrochemical compression technologies in the course of the project. Electrochemical compression has substantial benefits with regard to efficiency, hydrogen quality and the cleaning of hydrogen.

Innovative on-demand services: Shuttle system at Graz airport

In addition to the conversion of drive technologies, the aim is to drive forward innovations in the area of demand orientation in the public transport system so as to make public transport systems more attractive in the future. In addition to the existing public transport system, innovative on-demand services are thus being developed and tested in move2zero with the involvement of users. The test operation of a battery-driven, demand-dependent shuttle system between Graz airport, suburban railway station and regional bus stop as an attractive and convenient link to the public transport network is being carried out. E-vehicles which are charged with an innovative, automated charging system via charging plates integrated in the roadway (matrix charging) are used. An innovative booking system has been developed and integrated into existing platforms for the booking of the shuttle.

To determine requirements and develop the optimum operator concept of the on-demand system, anonymised mobile communications data are analysed and assessed. Another research focus in the project is a concept for a possible autonomous operation of this on-demand service in the future.

The project goals:

  • Zero-emission technologies for the provision of energy
  • Zero-emission technologies for the operation of the vehicles and infrastructure
  • Use of components with low emission factors and higher quota for re-use and recycling
  • Optimum adjustment to the demand and requirements of public transport users by developing & operating on-demand services
  • Comprehensive involvement of the citizens in the development and demonstration of innovative systems
  • Integrated concept for the decarbonisation of the bus transport system and transferability to other cities

New emission-free shuttle system at Graz airport

In the public transport system, the aim is to drive forward innovations in the area of demand orientation so as to make public transport systems more attractive in the future. In addition to the existing public transport system, innovative on-demand services are thus being developed and tested in move2zero with the involvement of users.

The test operation of a battery-powered, requirements-based shuttle system between Graz airport, suburban railway and regional bus stop is being carried out as an attractive and convenient link to the public local transport system. E-vehicles (Mercedes eVito) which are charged with an innovative, automated charging system via the charging plates (matrix charging) integrated in the road are used. For the booking of the shuttle, an innovative booking platform has been developed and integrated into existing platforms. To determine requirements and develop the optimum operator concept of the on-demand system, anonymised mobile communications data will be analysed and assessed.

Another research focus in the project is a concept for possible autonomous operation of this on-demand service in the future.

Project info:

  • Test operation6 months (anticipated to be 2021)
  • Route: Graz airport – suburban railway station – Abtissendorf Flughafenstraße
  • Vehicles: 2 Mercedes e-Vito (battery-powered shuttle; 9-seaters)
  • Ticket: free-of-charge service
  • Booking: call system (on-demand service) via www.grz-shuttle.at.
  • Charging system: conductive, automated charging system via matrix charging plates installed in the floor (system from the company Easelink). First test operation of this charging system in the public sector and in public passenger transport.

 

This project is financed with funds from the climate and energy fund within the “zero emission mobility” programme. The airport shuttle is also supported in the Styrian central region with regional funds pursuant to the 2018 Styrian Provincial and Regional Development Act.
