Project main objectives are:

  • Energy consumption reduction of the selected metro stations, since part of their base load consumption will be covered by the energy previously stored in the Hybrid Energy Storage System(HESS).
  • Resistors are placed on the wheels transforming the energy from regenerative braking into heat causing local temperature outbursts. Through MetroHESS project, the need for energy conversion will not be necessary.
  • Electricity cost reduction for the Metro Operator.

Project main research objectives are:

  • Technical efficiency and economic feasibility of the HESS to be applied in Athens metro and similar infrastructures.
  • Improvement of the methodology for the conceptual design of the HESS.
  • Development of different energy management strategies for HESS.

Project main expected results are:

  • If the outcomes of the project show that the investigated application of the HESS is energy efficient and economically feasible, the results can be used in a follow-up project, e.g. the implementation of such a system in larger scale. The proposed methodology can be easily adapted for other metro or urban railway systems. Therefore, the project forms the basis of numerous possible applications of HESSs and can contribute to a significant impact towards the energy efficiency of the Transport sector.
  • The HESS energy management strategies can be used for further commercial exploitation.
  • The scientific results regarding the conceptual design methodology and the energy management strategies will be shared with the scientific community and will find entry into teaching.

The project will be an excellent opportunity to discuss and improve the resulting methods and concepts directly with companies active in the Transport sector and results being transferred afterwards to industry.

The enhancement of the cooperation between the research institutions themselves, the industrial part­ners and commercial companies (especially small and SMEs) will be strengthened.
