New info portal: large heat pumps as the future of heat supply!

In the middle of changing the energy systems, which presents industry and thermal industry with challenges, large -scale heat pumps are becoming increasingly important. This key technology is now made more accessible by a new info portal, which provides comprehensive information about products, manufacturers and realized projects. The Hessian Minister of Energy Kaweh Mansori emphasizes that the portal plays an important role in the development of climate -neutral heat networks and industrial processes. The portal was developed by Fraunhofer IEG and Lea Hessen on behalf of the Hessian Ministry of Economic Affairs and is therefore the first European portal to provide comprehensive information on large -scale heat pumps.

Large heat pumps are able to produce temperatures up to 200 ° C, and even steam compressors enable temperatures up to 300 ° C. These high temperatures are particularly in demand in metal processing and chemistry, where they have so far been often provided by fossil fuels. In contrast, innovative technology uses renewable energy sources such as environmental heat and industrial waste heat. Studies show that the range of environmental and waste heat in Germany exceeds the heat requirement for buildings and industrial processes up to 200 ° C, with potential heat outputs of around 1,500 terawatt hours.

the info portal and its functions

The new info portal offers various functions that enable planners and operators of heating networks as well as energy -intensive industries to search specifically for suitable products. Users can filter the database according to the power range, temperature range and refrigerant category. In addition, information on technologies, refrigerant selection and an efficiency calculator are integrated. The goal is to further promote the applicability and spread of large -scale heat pumps.

Currently around 60 megawatts installed in Germany are available in large -scale heat pumps, but forecasts indicate that direct flash of tidal heat could provide over 70 % of district heating by 2045 and largely replace natural gas. To achieve this, it is necessary to add four gigawatts of new large heat pump output annually. Pilot projects are already in operation in Hesse, which represent examples of success for the use of large -scale heat pumps: from the TU Darmstadt, which uses a 550 kW large heat pump, to the residential area in Frankfurt Sachsenhausen, where geothermal energy has been used.

economic and environmental aspects

The need to increase the economy of large -scale heat pumps compared to fossil solutions is clear. The annual heat requirement for temperatures up to 200 ° C is over 1,000 terawatt hours, with heat generation in this area over three quarters of German natural gas consumption. This has an impact on greenhouse gas emissions, which could be significantly reduced by switching to large heat pumps.

However, the implementation is not without challenges. It takes a clear expansion path to increase the use of large -scale heat pumps and reduce price disadvantages compared to fossil fuels. Suggestions on the reform of the power-heat coupling law and the increase in funding programs are discussed in order to create incentives for green heat solutions. It is crucial to develop a clear target for the planning security of the manufacturers.

With the progressive development of large -scale heat pumps, technical applicability is becoming increasingly versatile. These can not only be used in new buildings, but also in existing buildings, and they support defossilization and the electrification of heat supply.

The large-scale heat pump info portal is now available online at www.grosswaermePumpen-info.de . For detailed studies and further information, interested parties can be found on the reports of fraunhofer isse access.
