This study analyses various potential heat sources for operating heat pumps. These include air, water, geothermal energy, waste heat, solar thermal energy and energy from the sewer system. Each source is evaluated in terms of its technical and economic feasibility.
Other key issues addressed by the project include grid compatibility and the existing electricity infrastructure, the seasonal efficiency of the systems, and aspects of security of supply. In addition, the current funding landscape and the economic viability of the respective solutions are examined in detail. A particular focus is placed on the use of industrial waste heat and the possibilities for sector coupling.
In addition, topics such as land availability, approval processes, social and ecological impacts, and the development of various scenarios up to the year 2045 are being examined. The aim is to develop a comprehensive picture of the potential, challenges and possible solutions for the use of heat pumps outside the district heating expansion area in Innsbruck.
