Sustainable urban Planning with Innovative and low energy Thermal And power Generation fröm Residual And renewable Sources (PITAGORAS)
Date du début: 1 nov. 2013, Date de fin: 31 oct. 2017 PROJET  TERMINÉ 

The project is focused on efficient integration of city districts with industrial parks through smart thermal grids. The overall objective of the project is to demonstrate a highly replicable, cost-effective and high energy efficiency large scale energy generation system that will allow sustainable urban planning of very low energy city districts.The main focus of the project is medium (150-400ºC) and low (30-150ºC) temperature waste heat recovery from industry and its use for energy supply to cities.The following systems and concepts will be developed:- Waste heat recovery systems- Organic Rankine Cycle for heat and power generation- Thermal energy storage systems (short and long-term)- Optimized thermal energy distribution network (low temperature thermal grids)- Solar thermal energy- Optimized integration of new technologies and concepts developed and state-of-the-art renewable energy systems- Innovative tools for efficient energy management of the systemThe concept of the project will be demonstrated at two different European cities: Brescia (Italy) and Graz (Austria).- Demonstration plant in Brescia: medium/high temperature waste heat recovery (600ºC) from a steel foundry and ORC unit (2,1 MWe) for heat and power generation. District heating to a city district nearby.- Demonstration plant in Graz: Seasonal thermal energy storage system for the management of the surplus waste heat in the city thermal network. Solar thermal energy (10.000m2) as support energy system, increasing the RES contribution in the city of Graz from 0,5% to 0,9%. Heat supply to a residential area nearby.
