Extract heat from data centres

Data centres and society have much to gain from the use of excess heat. Learn how to extract heat in the Nordic countries and make your data centre more sustainable.

Four reasons to invest in heat extraction

  • Data centres produce large amounts of excess heat, which today is largely wasted. And for many data centres this represents a massive potential in the journey towards decarbonizing operations.
  • The world is in the middle of a global energy crisis. Energy prices are skyrocketing. Your company can help Denmark with the green transition and stop the dependence of Russian gas.  
  • The European Commission suggests that all data centres of more than 1 MW should perform a cost benefit analysis to investigate whether the excess heat can be used in the district heating supply.
  • The tax on excess heat based on electricity has been lifted in Denmark.

Ramboll and datacentres in in the Nordic countries

  • : +10

    Rambøll is currently working on + 10 projects for data centres in the Nordic countries.

  • : +350,000

    Data centres in Scandinavia could soon supply more than 350,000 households with heat, if they invest in heat extraction.

  • : 12.000

    Ramboll is the first and only company to design a heat extraction facility for a hyperscale datacentre. The energy is used to heat 12.000 households.

  • Redistribute excess data centre heat

    A Ramboll-designed energy centre is redistributing excess heat from Meta’s data centre in Odense to the city’s district heating network. Data centres produce large amounts of excess heat, which today is largely wasted but could play a vital role in the green transition contribute to the data centre industry’s sustainability.

  • Help supply heat for 100,000 households

    In the coming years, 400,000 households that are heated by natural gas will switch to district heating or heat pumps. The companies can supply climate-friendly excess heat to 100,000 households, according to an analysis conducted by Ramboll in collaboration with The Danish Energy Industries Federation (DI Energy).
