A distinguished delegation from the Polish district heating sector visited Denmark from June 16 to 18, 2025, to gain insight into Denmark’s leading-edge district heating technologies and foster bilateral cooperation. The visit, organized in collaboration with DBDH, the Danish Board of District Heating, offered a rich program of workshops, site visits, and networking opportunities across multiple Danish regions.
Sharing visions and technologies
The program commenced Monday morning at the DBDH headquarters in Frederiksberg, where Polish and Danish stakeholders exchanged strategic perspectives on the future of district heating. The Danish Energy Agency introduced the Danish approach to modern district heating, followed by the Polish association IGCP, which outlined the challenges and ambitions within Poland’s energy transition.
This was followed by three in-depth parallel workshops showcasing innovative solutions:
- Modern technologies in district heating (featuring Dall Energy and Fenagy),
- Renewable energy production and planning (presented by Inopower and Danish Commodities), and
- Energy efficiency and low-temperature systems (with contributions from Kamstrup, Grundfos, Desmi, and Kingspan-Logstor).
Each session highlighted Denmark’s experience with decarbonization, integration of renewables, and digitalization—all highly relevant as Poland modernizes its district energy systems.
Field insights across Denmark
The delegation then visited Sorø District Heating, operated by AffaldPlus, where they explored biomass-based heat production and the practical aspects of converting small communities from gas to district heating. This visit offered crucial lessons on overcoming geographical and infrastructural barriers in rural areas.
On Tuesday, the group toured Kamstrup’s automated production facilities and learned about Kredsløb’s green transition strategy in Aarhus, including their ambitious waste-to-energy operations at the Lisbjerg Energy Park. Visits to GUES in Bjerringbro showcased integrated energy systems including ATES, while the partnership with Grundfos underlined the potential of industrial collaboration in achieving energy efficiency.
Advanced technologies in Northern Jutland
Wednesday’s program brought the delegation to three northern district heating pioneers. At Aars District Heating, participants learned how the utility is phasing out waste incineration in favor of large-scale heat pumps and thermal storage. Støvring District Heating offered a glimpse into advanced electrification technologies, including CO₂ heat pumps and ammonia-based systems.
The final site visit took place at Dronninglund District Heating, where the utility’s transition from waste incineration to one of the world’s largest solar heating installations was showcased. The facility’s integration of solar thermal collectors with pit heat storage and thermal absorption heat pumps presented a compelling model for seasonal energy balancing using renewables.
Strengthening cooperation for a greener future
Throughout the visit, discussions emphasized the importance of knowledge sharing between Denmark and Poland. With both countries facing ambitious decarbonization goals, the delegation identified clear opportunities for continued dialogue, joint projects, and technology transfer.
The three-day program left delegates with actionable insights, new professional connections, and a shared commitment to advancing sustainable district heating solutions.
