More flexibility for more renewables in district heating systems - the flagship project "Thermaflex"
In 2016, Austria's space heating requirement amounted to approx. 87 TWh/a (total energy requirement: 311 TWh/a)1. A quarter of this demand is provided by district-heating based heat supply through more than 2000 district heating systems1. Thus, the district heating sector already plays a central role in Austria's energy supply. Due to the already installed infrastructure (approx. 5,400 km pipe length2), the existing expansion potential, especially in dense urban areas, the application of new concepts, technologies and renewable energy sources, the growing possibilities for sector coupling and the resulting contributions to the decarbonisation of our energy system, the district heating sector will become increasingly important in the future.
