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 data centers (server hotels), which are already now under construction in many countries around the world. The challenge – that often there is no convergence between production and consumption time – is a big one in the electricity sector, but smaller in the district heating sector, as the
Therefore, we are already now seeing district heating systems, even in Denmark where the sun does not shine so much, where more than 50% of the annual heating requirement in a district heating system can be covered by solar heating. The explanation? That heat production in the summer is stored in a large underground seasonal storage, after which the energy can be used from the storage through the autumn and the first part of the winter.
And so the adventure of DBDH does not end with the 40th anniversary of the association. No - with an increasingly clear message regarding: • that we must reduce the use of fossil fuels such as natural gas, coal and oil, • an increasing need for integration between electricity and district heating systems, • an increasing desire to exploit renewable energy - including geothermal, • an increasing demand for utilization of surplus heat from the current industry, as well as the future industry (e.g. biofuel plants) An expansion of district heating systems - as part of the necessary infrastructure in modern society - will be a matter of course. There will be an increasing need for the experiences and competencies found in one place to be made available and act as inspiration for players elsewhere. DBDH will act as this link in the coming years, so that the ”Hans Christian Andersen fairy tale” from 1978 can continue for many years to come. But what fairy tale was it then – maybe the Ugly Duckling? We did start from a humble platform; whether we developed into a beautiful swan, we will leave for others to decide.
