Heat Pumps for a sustainable future

Heat from servers in data centers is normally not reused, but instead wasted and released into the surroundings of the data center, creating an heat island. Our data centers are integrated in larger energy ecosystems, where the heat from the data center is reused for heating buildings or providing heat to industrial processes. Heat pump technology is a key technology for the future, and we are using heat pumps to increase the temperature from the data center up to 95 °C.

Our data center in Falun is located next to a Combined Heating and Power (CHP) plant that enable reuse of heat from the data center for production of wood pellets in an existing plant and to produce heat for an existing district heating system. Reusing heat from the data center eliminates the marginal use of fossil fuels (like LPG and heating oil) in winter.

CO₂ Heat Pumps

Some of our heat pumps are made from standard components that are specifically designed and approved for high temperatures with the environmentally friendly and future-oriented refrigerant CO₂ (R744).

Absorption Heat Pumps

The data centre in Falun is located next to a CHP plant that enable the use of highly efficient absorption heat pumps. They use steam as driving energy, and no electricity is required to produce prime district heating.

Data Center heat Produce Renewable Wood Pellets

Heat from the data center in Falun will be used for the drying process in the nearby wood pellet factory that normally is closed during the winter as there is a shortage district heating capacity. More renewable wood pellets energy can be produced to be used in the district heating system and for other customers using fuel oils for heating.

Data Center heat Used For District Heating

Heat from our data center in Falun is used in the district heating system during winters. This eliminates heat production with fossil fuels like LPG and heating oil that has high CO₂ emissions.

This CO₂ replacement combined with the CO₂ savings from wood pellets production exceeds total CO₂ emissions from production of electricity used by the data center during a year. The net effect is a reduction of total CO₂ emissions in the energy ecosystem. This creates the first climate positive data center in the world.
