From 15–17 May, DBDH had the pleasure of welcoming a high-level Dutch delegation of 17 mayors from the G40 network to Copenhagen. Their mission? To explore how Denmark is transforming its district heating (DH) systems to meet ambitious climate goals — and what lessons can be brought home to the Netherlands.
Over the course of three days, the delegation visited a variety of pioneering DH sites across Greater Copenhagen, each showcasing different aspects of sustainable heat supply:
- Egedal Fjernvarme demonstrated how smaller systems can efficiently integrate solar heat, biomass, and storage, along with plans for future expansion.
- Høje Taastrup Fjernvarme showcased large-scale heat pumps and thermal storage, highlighting the municipality’s transition away from gas.
- Albertslund Fjernvarme impressed with its low-temperature network, innovative project proposals, and stakeholder collaboration — joined in part by Mayor Steen Christiansen.
- ARC Waste-to-Energy Plant, topped with its iconic ski slope, provided a panoramic view — literally and technically — of how waste is converted into citywide energy.
The visit concluded with a hands-on workshop at DBDH’s headquarters, where participants, steadily guided by Morten Jordt Duedahl from DBDH, engaged in discussions on tariff structures, city-scale planning, and business models for decarbonised heat. This open exchange underlined the shared challenges and opportunities in transitioning urban heat systems toward a fossil-free future.
The visit exemplified how cross-border collaboration can spark new thinking, build networks, and accelerate action at the local level.
