Programme for NL Delegation vist to DK Spring 2023

DBDH publishes Hot Cool, but the main business is helping cities or regions in their green transition. We will help you find specific answers for a sustainable district heating solution or integrate green technology into an existing district heating system in your region – for free! Any city, or utility in the world, can call DBDH and find help for a green district heating solution suitable for their city. A similar system is often operating in Denmark, being the most advanced district heating country globally. DBDH then organizes visits to Danish reference utilities or expert delegations from Denmark to your city. For real or virtually in webinars or web meetings. DBDH is a non-profit organization - so guidance by DBDH is free of charge. Just call us. We'd love to help you district energize your city!

A wish list from the Dutch participants to what would be nice to learn and understand deeper (Not complete)

Dutch District Heating Visit to Denmark March 22 nd – 24 th , 2023

Connection of DH in existing buildings: - Construction and integration of a DH in the build environment. What is your approach, How is it different from new buildings and what kind of role does a municipality have in this, do you need a sufficient scale to make it affordable and if yes how much? - Do you have standard connection methods to connect existing buildings to DH? - Who pays for the cost to connect existing buildings? (and also the risk in the construction phase, or example if a building has a lot of asbestos of rotted concrete. - Do you have examples of Public-private partnerships and if yes how are they organised. In the Netherlands we have a lot of discussions about special integration Especially in cities, there’s little space in the underground and in the public space. It’s a challenge to fit in all the city tasks (like green public space, adaptation measures, preventing heat stress) and to fit in DH. (in Rotterdam we have developed an ‘spatial integration ladder’ for this). Also large heat pumps are likely to become the standard for heat grids. How will these be spatially parked in DK? At a distance from buildings, or are there applications of multiple use of space by e.g. heat pump on first floor and offices/homes on top? And how do you deal with special integration of DH in cities/municipalities? Spatial integration/ fitting in DH in public space and underground - Tariff regulation: - How do you divide the cost of DH between different home owners (in the Netherlands, the small end- users are regulated, the large end- uses aren’t. - In Denmark DH companies are not allowed to make profit. How do you monitor this? The rate of return in a project is at the beginning negative (because of large investments) and in the end its positive. How do you monitor that the rate of return will be 0%? In the Netherlands we have some discussions with DH companies about this. DH cooperatives - Do you stimulate DH cooperatives in Denmark and if yes, how do you do this? What kind of law, regulation and instruments are needed to stimulate DH cooperatives? Innovation - How is innovation stimulated in Denmark? Perhaps it is interesting to give a presentation about the twin pipes (or other innovatio ns). They’re not very known in the Netherlands. Also a really big difference between Denmark and the Netherlands is that in Denmark you much more steer on efficiency of the system. For example DH monitor the supply and return temperature from customers and try to lower the return temperature. In the Netherlands we don’t see DH companies do that. Perhaps you can explain the advantages of it. Ideas to discuss: - Increase public acceptance of heat source with a 'share' in the heat source. In the Netherlands we have local shareholding in wind farms, but not yet in heat sources. Do you have examples for this in Denmark? If yes, how are they organised: with financial share, or as a "discount" because you are a user or another way? - Is more a discussion for the Dutc h municipalities and the grid operators, but I’m also curious about your view on this: what kind of view have the municipalities on a DH supplier. Should a DH company be an integrated DH company or can you split it in a grid operator and supplier? What are the risks and pros and cons? Can this also be a role for the grid operator or do the municipalities want private companies to take this role? (do you have split models in Denmark?)
