Digitalisation: More Renewable Energy in District Heating Systems

A recently published guide and a video show how digitalisation can optimise district heating and cooling systems. In a project organised by the International Energy Agency, researchers from eleven countries have developed corresponding solutions.

According to the University of Kassel, cooling units, such as the free cooler shown here, will probably be the most common source of waste heat for heat pumps in industry in the coming years.

Customizing Systems for Renewable Heat Supply

Researchers have analysed the heat consumption of 797 companies in Germany. The findings will make it easier for companies to plan their heat supply with fluctuating producers such as solar thermal energy and with heat pumps in the future.

96th ExCo Meeting IEA Energy Storage TCP
Economic Efficiency and Integration of Energy Storage Systems are Topics at an International Level

Powerful storage systems make it possible to use heat and electricity flexibly over time. The Energy Storage Technology Collaboration Program brings together these technology developments at an international level. Delegates from around 20 partner countries recently met in Berlin.

River Heat Pump in Mannheim Supplies Climate-Friendly Heat

A large heat pump at the Mannheim power plant (GKM) is now supplying around 3,500 households with heat, which is also obtained from the Rhine water. The 20-megawatt plant is currently the largest heat pump integrated into a district heating network in Germany.

Based, among other things, on the European Green Deal and with a view to the commitments under the Paris Climate Agreement, the EU wants to significantly reduce greenhouse gas emissions (symbol image).

Important milestones reached in the living lab for the energy transition
Save CO2 with Large-Scale Heat Pumps

In the supply of district heating, the integration of large-scale heat pumps can reduce CO2 emissions. The living lab for the energy transition “GWP” is showing how this is possible at five differently structured power plant sites. The operation of such a plant has been started in Stuttgart-Münster.

The potential of shallow geothermal energy for Germany’s heat supply is to be utilized more effectively. To achieve this, a nationwide standardized database is to be created in the WärmeGut project.

Launch of WärmeGut Project
Geological Information for Transforming the Heating Sector

Ground-source heat pumps are a promising option for achieving a net-zero heating supply. However, information on suitable locations for these geothermal heating systems has not been centrally available. In the WärmeGut project scientists are now developing a nationwide standardized database.
