Wien Spittelau High Temperature Heat Pump
THERMAFLEX DEMO PROJECT: Use of the heat from the flue gas by means of a high-temperature heat pump
This demo is part of the lead-project ThermaFLEX that has been completed successfully. Download the final report.
Objective of the project ThermaFLEX Wien Spittelau High Temperature Heat Pump
In this project, the approach of so-called sector coupling is pursued, i.e. the merging of different, previously separate systems. At the waste incineration plant in Vienna-Spittelau, it is planned to use the waste heat from the flue gas condensation (latent energy) of the incineration plant as an energy source for a high-temperature heat pump. Taking into account the results of the evaluation of different operating strategies, a direct feed into the primary district heating network of the city of Vienna will be possible.
Approach and methodology of the project ThermaFLEX Vienna Spittelau high-temperature heat pump
The thermal capacity of the planned heat pump concept is approx. 16 MW, which will increase the thermal capacity of the waste incineration plant from 60 MW to approx. 76 MW. The multi-stage construction process is scheduled to start in 2022 and be completed by the end of 2024.
The main advantages of the proposed system are the increase in the overall efficiency of the incineration plant, the use of waste heat for the district heating network, the reduction of primary energy for the district heating supply, the reduction of CO2 in the heat generation, the reduction of the waste water input to the waste water treatment plant and the internal use of the condensate produced.
The following model solutions are being developed in the Wien Spittelau High Temperature Heat Pump project:

Burn in the best possible way
In the Spittelau waste incineration plant, a modern heat pump based on the Scandinavian model is to use the heat from the flue gas. This saves water, C02 and supplies thousands of additional households with heat.

A new large-scale heat pump at the Vienna Spittelau waste incineration plant will heat 16,000 Viennese residents in future. An additional 16 megawatts of power will increase the efficiency of waste incineration by 13 percent. The plant is a ThermaFLEX demonstration project in the Green Energy Lab portfolio.
