Hot and Cool topics on District Heating and Cooling

Social sustainability is the “missing pillar” in many district heating strategies. In this episode, Hanne Kortegaard Støchkel (DBDH) talks with Kristina Lygnerud and Johanna Aurault about how to integrate social value into every stage of the district heating value chain.From a Canadian case study in Burnaby to practical tools like social KPIs, they explore how municipalities and companies can work together to improve community well-being, strengthen business cases, and stay competitive.🎯 For: Business developers, municipal decision‑makers, and energy professionals.Social sustainability is often overlooked in district heating, yet it is essential for creating energy systems that are resilient, inclusive, and trusted by communities. It goes beyond economic and environmental goals to address the broader social impacts of energy projects—ensuring benefits are shared across stakeholders, from employees and customers to local communities and future generations.A recent study funded by the International Energy Agency explored this in Burnaby, Canada, revealing key differences from the European context. While Europe often frames social sustainability around fuel poverty, Canadian stakeholders linked it to health, climate resilience, and urban planning. Interviews with a wide range of stakeholders—from architects to disaster management offices—showed that district heating’s value extends far beyond its core function.Social sustainability can be embedded at every stage of the district heating value chain, creating opportunities for innovation and stronger community ties. Social Key Performance Indicators (KPIs) help measure these impacts, with many benefits—such as community education, inclusive urban design, and improved cityscapes—being non-monetary but highly influential.Drivers include both external pressures (legislation, procurement requirements, public expectations) and internal motivations (competitiveness, talent attraction, stakeholder trust). Municipalities can lead by setting clear social sustainability criteria and integrating urban and energy planning. District heating companies benefit by aligning with these expectations, building partnerships, and enhancing their business cases—turning social engagement into a competitive advantage.The shift towards social sustainability is not about technology—it’s about mindset. Strong relationships, cross-sector collaboration, and deep community integration will define the most successful and future-ready district heating projects.

Guests: Tony Dam Jensen (Sønder Felding District Heating) and Ebbe Nørgaard (Fenagy)What happens when a small Danish town dares to think big?In this episode, we explore how Sønder Felding has transformed its local district heating system into a cutting-edge model of electrification, flexibility, and ultra-low-cost heat. Manager Tony Dam Jensen and Fenagy’s Ebbe Nørgaard share how large heat pumps, thermal storage, and smart market participation are unlocking new opportunities - not just for heating companies but for entire electricity grids.This is Power-to-X in action. It’s not complex. It just works.

As Europe intensifies its shift from fossil fuels, a lesser-known player is “making waves” in the clean energy transition: aquathermal energy. Tapping into the latent heat of water bodies, this technology promises to redefine sustainable heating.In this first episode of the WaterWarmth podcasts, host Lesya Logvynenko is joined by Lenn Coussement from Extraqt and Lars Zwaaneveldt, a Dutch policymaker, to uncover the potential of aquathermal systems. From technical feasibility to policy roadblocks, they explore whether this emerging solution can scale up – or if it will remain a niche experiment in Europe’s energy mix.🎧 Tune in to find out!

A partnership between the City of Burnaby and Metro Vancouver is driving the development of district heating in the area. The initiative will leverage excess heat from a Waste-to-Energy plant to reduce emissions and offer space heating at competitive prices. Dive into the highlights and discover why stakeholders and investors show strong interest in the project.

District heating can make you think of many things – for me, it is not often that Robbie Williams is in the back of my head singing along to a DH podcast about very large heat pumps. Nevertheless, that is what Raymond Decorvet from MAN Energy Solutions and Claus A. Nielsen from Esbjerg DH company (DIN Forsyning) managed to do during a podcast about large heat pumps and how to include them in the heat portfolio for a large DH company in Denmark.

"What is the greater value of heat planning - to cities, citizens, and society?"To give input on that topic, we have invited Mayor Steen Christiansen from the municipality of Albertslund, chairman of the heat transmission company VEKS, and board member of the Danish DH Association to discuss with Volker Kinzlen, Managing Director of KEA, BW.

Morten Jordt Duedahl is back with two top experts, Jørgen Nielsen, chairman of DBDH and managing director of TVIS, and Oddgeir Gudmundsson, who has looked deep into many aspects of district heating and has made new ways to compare DH and hydrogen. He is the scientist in this podcast.

In this podcast episode, Charlotte Owen takes over from your usual host, Morten Jordt Duedahl, to talk about the important topic of gender diversity in the heat networks industry. She is joined by two fantastic women, Rachael Mills of SE2 and founder of the District Heating Divas, and Kamma Eilschou Holm, Director of CTR, a heat network transmission company in Copenhagen. This podcast episode is for all the women and people whose identity includes womanhood who have ever experienced imposter syndrome walked into a room and realised they were the only woman in it. Or put on an enormous pair of safety goggles and hoped no site visit photographs would be taken.It is also for anyone who wants to know more about experiences being a woman in the heat networks industry or who wants to help champion diversity. Whoever you are, we hope this makes you feel a little less alone and a little more included.

District heating networks are some rather expensive infrastructures and should last as long as possible. Managers of DH networks focus on how best to maintain and secure their networks. When the pipes are in the ground, the only factor one can control is nearly the operation and maintenance cost – it is tough to see the pipes again, or maybe not that hard if done from above. For this interview, Morten Jordt Duedahl has invited two specialists in surveying DH networks to discuss how it is done. Bo Jensen Møller, Head of Operation at the Copenhagen DH company HOFOR and Sune Nielsen, tech- and drone wizard, inventor, and COO of the Danish company Drone Systems.

Morten Jordt Duedahl has invited Jens Andersen, managing director of Naestved District Heating, and Jesper Moeller-Larsen, managing director of the DH company in Aalborg. Both are working on converting more of their cities from gas to district heating every day in Denmark. The aim is to inspire others to start their gas conversions and, as always, an invitation to knowledge sharing. We will focus on how to implement conversions.

Morten Jordt Duedahl has invited Hrvoje Klobucar from the Croatian city Karlovac and Johan Sølvhøj Heinesen from Egedal DH Company north of Copenhagen in Denmark to discuss ways to Greener District Heating. Both are managing directors of their DH companies, and both have long experience in our industry. The two gentlemen discuss the challenges with going green, converting from natural gas to DH (also an interpretation of going green), ownership, and how to attract more customers to the companies. In the last part of the podcast, you will get their advice on managing the green transition in the best possible way.
