When the refrigerated counters in the supermarkets run and the data center servers process data, heat is created.
In the future, a larger part of the excess heat will be used to heat radiators around Danish homes.
That is the intention of a new broad agreement that the government and a number of parties have entered into.
– It may sound strange, but the cooling counter in the local supermarket can actually help keep the radiator warm, says Climate Minister Dan Jørgensen (S) in a press release.
– It makes good and green sense to reuse the heat that appliances and systems create to heat private homes. It saves both resources and helps the climate.
The new agreement means that suppliers of the surplus heat and the district heating companies can in future agree on a price directly with each other.
However, it requires that the total cost of utilizing the surplus heat is kept below a fixed price ceiling for how much it is estimated to cost if the district heating company were to produce the heat in another way – for example by investing in a heat pump.
It must provide a stable framework for regulating the price of surplus heat.
At the same time, small businesses with a surplus heat capacity of less than 0.25 megawatts – which is equivalent to 10-25 households being able to be kept warm on a cold winter day – are exempted from price regulation.
Surplus heat from supermarkets and smaller data centers in particular benefits.
The new agreement is called “a huge gain for the climate” by Danish Industry, which is the country’s largest business organization.
Dansk Industri has previously estimated that a further up to 128,000 single-family houses can be heated by surplus heat through the district heating network. Thus, less energy from other sources such as coal or biomass must be used.
– It is a huge benefit for the climate. It shows the way to the green society of the future, where the production of energy and consumption are linked in a completely different way than today.
– In this way, we get even more green examples that we can show to the rest of the world, says Lars Sandahl Sørensen, CEO of Danish Industry, in a press release.
The new agreement will enter into force in 2022.
