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.
