HOT|COOL NO. 4/2021 - "Going Greener"

A completely newway of doing articles in Hot Cool is podcasts. The theme in this magazine is ”Going Green,” To discuss that, we have invited Hrvoje Klobucar from the Croatian city Karlovac and Johan Sølvhøj Heinesen from Egedal DH Company north of Copenhagen in Denmark. 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. PLANNING IS KEY - and seek inspiration fromothers

The conclusion is... The situation in the two cities is quite different, and maybe also quite similar. The result is that we agree on what is essential for district heating companies to go green and remain com- petitive. The conclusion is to plan very well. Planning will keep your opportunities flexible, the prices as low as possible, and give access to several heat sources so one can optimally mix the heat supply, taking care of both costs and sustainability. A well- planned and well-constructed systemwill provide the DH com- pany more options to use a different fuel mix dependent on price fluctuations for each of them and prioritize green fuels. This approach can make your systemmore flexible from day to day and at the same time from decade to decade. Also, we agree that seeking inspiration from others is the way forward. Hrvoje Klobucar seeks inspiration from Denmark. But one should seek inspiration from everywhere possible. That is also what the Best Practice study survey (mentioned in this magazine) found through a pan-European study done with 8 DH companies. Getting new customers Winning customers is always a challenge due to a lack of knowledge of district heating and the perception that DH is too expensive. But bringing new customers on is also a part of going green, as you can convert them from a strict fossil heat source (natural gas) to something that is greener and has the option to develop even further in a green direction. In Egedal, they convince up to 70% of the potential customers in areas today served by gas to convert to district heating – well done! Here they do a lot of marketing to promote the offer

Listen to Johan from Egedal DH company north of Copenhagen and Hrvoje from Karlovac, Croatia, discuss how to make district heating greener. This podcast is also an excellent opportunity to learn about the differences between district heating in Denmark and Croatia.
