Decarbonisation of greenhouses with thermeco2 high-temperature heat pumps
As an environmentally friendly alternative to fossil burners, thermeco2 high-temperature heat pumps are driving decarbonisation and sustainable food production. In this project, five thermeco2 HHR1000s with a total heat output of 5 MW contribute to the zero-carbon strategy in the greenhouses of the Osatina Group.
"The thermeco2 high-temperature heat pumps are the perfect solution for the flow temperature required by the customer and the associated temperature spread."
Frank Glaser, Key Account Manager Industrial & Commercial Heating
- The heating system in the greenhouses requires three different temperature levels:
- Highest temperature level: 85 °C
- Medium temperature level: 60 °C
- Lower temperature level: 40 °C for vegetation heating
- Fossil burners must be replaced without modifying the installed heating system.
- Water-to-water heat pumps for indoor installation
- Heat sources
- Winter: Geothermics
- Summer: In the warm season, thermeco2 high-temperature heat pumps enable simultaneous hot and cold water production. As a result, the primary energy used is optimally utilized and thus saves the customer an additional chiller. This free cooling power is used to air-condition surrounding farms and to cool domestic water.
- Operating hours: 5,000 p.a.
- Our solution will produce hot water from environmental heat in the future, with the majority of the required electrical energy coming from a photovoltaic system. Due to the decarbonisation and sustainability aspects of the project, it is subsidised by the EU with more than 40% of the total investment.
- Energy-intensive industry
- Future-proof and long-term security of heat supply
- Independence from gas and the associated cost pressure of fossil fuels
- Use of government funding and European subsidies
- Contribution to climate protection targets
- Improving the image of regional horticultural products "CO2-free vegetables”

The ALBA Group employs around 7,500 people, and is active in Germany, Europe and Asia with its ALBA and Interseroh brands. In 2015 alone, the recycling activities of the ALBA Group saved almost 5.9 million tons of greenhouse gases when compared to primary production, and around 51.8 million tons of primary raw materials.
SWR in Baden Baden
Combined heat and cold generation in the high-temperature heat pump generates thermal heat of 40/80 °C in parallel to the new large boilers and uses the waste heat directly from the chilled water network for climate application to do so.
New building for Klinikum Frankfurt Höchst hospital
Optimal energy efficiency for hospitals: The heat pump will guarantee the combined generation of cold and heat in parallel to the two new large boilers, generate thermal heat for heating drinking water.
Heat recovery at Soest University of Applied Sciences
The CO2 high-temperature heat pump from ENGIE Refrigeration was chosen because it can supply the required network temperatures, retain a reserve for supply temperatures up to 90 °C, and can also be operated in parallel to a district heat supply.
New office building in Heroldsberg for Schwan-Stabilo Cosmetics
An entirely new building was erected in Heroldsberg. The heat pump is located in the heating system in the cellar. The main task of the heat pump is to activate the probe array, as server cooling is to a large extent covered by free cooling.
