I assume, of course, that the biomass used consists of residual resources that are used only in a sustainable way, i.e. with a neutral CO2 balance. Individual heating will have restrictions on the type of heating as well as heat source, so that particle contamination is also avoided. Electricity and heat savings as well as storage technologies will have a significant impact on the efficiency and balancing of the overall system. Within the next 40 years, by 2058, district heating systems will have been improved and expanded, so that all heat and power from the industry and surroundings are utilized by the means of large heat pumps. Also, surplus wind power will be used in Denmark for district heating through heat pumps and storage. Trains are electrified and cars run on electricity or on bioelectric fuels / CO2-electric fuels. Commercial production will be largely electrified, but will also utilize surplus heat. The bioenergy share of waste is converted into biofuels and waste is also recycled. The vision will be made possible by working determined to establish a smart energy system. A huge effort to produce energy savings has made the systems suitable for low energy, and the energy system is designed with the highest possible synergies in order to secure the balance between energy production and consumption within Denmark's borders. In this way, we are making ourselves less dependent on unintentional incidents in the European electricity grid, and it will strengthen our current strong expertise to ensure smart solutions between the different types of supply. In 40 years, our world will be cleaner than today, and we can harvest the financial fruits of a foresighted energy policy, implemented in broad agreement across different political wings and Danish public and private companies.

Congratulations to DBDH on 40 years of strengthening good Danish energy solutions. For 40 years, DBDH has helped show the world a Danish supply model where companies and utilities together create good robust and environmentally friendly supply solutions to the citizens. In Denmark, the development of the joint supply solutions is the basis for having come part of the way to an even more environmentally and climate-friendly energy supply during these 40 years. But there still is some way to go – so why not have a look at how I hope and believe Denmark’s energy supply will look in years to come. In the next 40 years, we are looking into a future with a need for investments in the order of billions in the energy supply, and now is the time for choosing the most sustainable and strategically best solutions. We must make an effort to meet the promise of temperature increases of no more than 2 degrees Celsius, and we want to make sure that Denmark is in a strong competitive position in future climate technologies. Already by 2030, twelve years from now, it is our vision that Denmark's energy supply of power and heat will be 100 % based on green sources. Denmark will have an even stronger business sector on technologies that can ensure the spread of green solutions in other countries as well. As a result, there are more jobs than today in these sectors for the unskilled, the skilled and the highly educated. IDA (the Danish Society of Engineers) has estimated that the energy consumption can be significantly reduced – and significant energy savings are required. From then on, more than half of the primary energy to be used in Denmark will come from wind turbines - predominantly located on the sea, but also from more onshore wind turbines than today. Energy production from solar cells, solar heating, terrestrial heat, geothermal heating and wave energy must produce far more energy than today.

North American market, where the possibilities for increased focus on the use of district heating and energy efficiency were high. In the energy sector in Denmark, it was well-known that if you produced electricity alone, you only got an energy efficiency of around 40%, but if you connected heat generation to the production, the utility would rise to 80-85%. However, according to a Gallup survey in the US, more than 50% of the population had never heard of the energy crises in 1973 and 1979. "Within the next 10 years, there will be a fantastic market for district heating in the world, and the Danes must therefore make an effort to inform others that we have one of the most highly developed district heating systems and thus the industry and

We are back in the 1970s - in the period between the two energy crises in 1973 and 1979 which affected Europe as a result of wars in the Middle East – more precisely in June 1978. We are in H.C. Andersen's home town Odense, Denmark. A true adventure, as if written by Hans Christian Andersen, begins. THE BEGINNING In the summer of 1978, 16 Danish companies - among these several of the major actors in district heating, such as Bruun & Sørensen (subsequently purchased by COWI), Rambøll, JIP Valves (subsequently purchased by Danfoss) and Danfoss - decide to set up Dansk Fjernvarmes Eksportråd. Being an export association, it is only natural that the association also gets an English name - Danish Board of District Heating or, in short, DBDH.

know-how which other countries may benefit from”, was the conviction of DBDH's Chairman at the time Mogens Larsen. Already the following year, however, in 1979, came a request from the Germans. The association of German district heating plants convened in Flensburg. This afforded theconference participants the opportunity of a site visit in Denmark, where especially the district heating systems in Sønderborg and Odense were of great interest, as district heating systems in both cities were based on efficient co-generation of electricity and heating - CHP. DBDH had a tremendous beginning, which was due in part to significant political support from among others Foreign Minister Henning Christophersen (later vice president of

The person behind the formation of DBDH was Lennart Larsson, at the time alderman in Odense, who was chairman of Dansk Fjernvarme (the Danish District Heating Association) in the period 1974-1992. DBDH was established based on Denmark's high level and many years of experience in district heating. Indeed, the Danish experience in district heating - including waste incineration and combined production of electricity and heat (CHP) - can be traced back 75 years. All the way back to 1903, when the first "waste-to energy" CHP plant was built. Now this experience was being brought to the rest of those parts of the world where there was a need for the heating of buildings, but also a need to focus on efficient use of resources.

the European Commission from1985-1995). A beginning which meant participation in conferences in many different countries as well as handling inquiries from countries like Holland, Canada, USA, Japan, Belgium, Norway, England and Ireland.

DBDH wished to systematise the Danish export of district heating components and consultancy - and a number of Danish district heating companies were to contribute as a showroom for the results. One of the first markets being focused on was the

THE EIGHTIES AND FORWARD In 1985, the activity in DBDH has increased to such an extent that a separate secretariat in Odense is established for better coordination of activities. The location in Odense also ensures that the many foreign visitors can see first-hand how Danish district heating actually works in a large city. DBDH has now grown into consisting of 32 member companies.

DBDH's work is now focused on three "legs": • Publication of the magazine News from DBDH - today known as Hot Cool. • Export promotion and reception of foreign delegations. • Network for members of the association. News from DBDH (Hot Cool) is characterized by articles at a professional level that reach decision makers and technicians in district heating worldwide. Yes – Hot Cool is becoming the largest district heating magazine in the world outside of China

The big step for DBDH at the international district heating scene takes place in June 1985, where the association participates in

with readers in more than 60 countries - and the magazine is free! It is available in print or a digital version and can also be read on www.dbdh.dk. THE FUTURE Now 40 years have passed, and from the original 18 members, DBDH currently has more than four times as many, 77. This could then be the end of the great adventure that began in Hans Christian Andersen's hometown Odense back in 1978.

Unichal's international district heating congress in Copenhagen. (Unichal is now known as EuroHeat & Power). By this time, DBDH is an established and respected player on the international district heating scene. The beachhead, which DBDH has now established internationally, is being expanded through the conclusion of cooperation agreements with a number of national district heating associations in North America as well as in Europe and Asia. The cooperation agreements ensure the coordination of activities such as conferences and seminars, delegation visits, exchange of technical information as well as market information of mutual interest and structure.

number of countries in the Baltic and Eastern Europe. Yes - the new markets thus, for a number of years, remove the focus from North America and Western Europe, as the new markets historically have a large prevalence of district heating. At the same time, many of these district heating systems were very worn down and the systems also heavily lag behind technologically. For that reason it is only natural that the attention is directed at these markets over the next 20 years. With the growing interest in Danish district heating technology in China, it seemed natural that DBDH established an independent unit in the form of a subsidiary organization in Beijing, DBDH China, to meet the interests of those members who focused on the Chinese

Although district heating is an old concept (moving hot water from point A to point B), the technological development has not been stagnant over the past 100 years. Over the past 100 years, district heating systems have evolved from generation to generation with still less demand for the flow temperature and thus increasing efficiency.

Today many district heating systems are established as 4th generation district heating systems (4G DH) with flow temperatures as low as 50-60 °C - indeed, some systems are established as Ultra Low Temperature District Heating (ULTDH) systems with flow temperature as low as 40- 50 °C.

establishment of storage capacity in a district heating system is significantly cheaper than in the electricity system - 1/60.

With these very low demands on the supply temperature, district heating will partly be able to directly exploit renewable energy in the form of solar power from large solar panels (several million m2), and the huge amounts of waste heat that we already have in our communities can be utilised. And here the very large amounts of surplus heat are not even included that will come from large >Page 1 Page 2 Page 3 Page 4 Page 5 Page 6 Page 7 Page 8 Page 9 Page 10 Page 11 Page 12 Page 13 Page 14 Page 15 Page 16 Page 17 Page 18 Page 19 Page 20 Page 21 Page 22 Page 23 Page 24 Page 25 Page 26 Page 27 Page 28 Page 29 Page 30 Page 31 Page 32
