Data centers transform waste heat into energy efficiency gains

Article published by Data Center Knowledge on February 24

A recent article from Data Center Knowledge explores how data centers are increasingly transforming waste heat into a valuable resource, improving energy efficiency while delivering benefits to local communities. As demand for digital infrastructure grows, operators are adopting new technologies such as heat pumps, advanced cooling systems, and integrated design strategies to capture and reuse thermal energy that would otherwise be lost.

The article highlights several global examples of waste heat recovery, with a strong focus on district heating systems. atNorth is featured for its approach to heat reuse across its Nordic data centers, where excess heat is captured and redistributed to support local municipalities and infrastructure.

One example includes the DEN01 data center in Denmark, where waste heat from liquid cooling systems will be repurposed to heat more than 8,000 homes through a partnership with Vestforbrænding. As Chris Larsen, CTO at atNorth, notes: “We are investing in ensuring that all our data centers are prepared for heat reuse, supplying heat not only to heat homes and local businesses but also to other applications such as greenhouses for local vegetable cultivation.”

The article underscores how heat reuse is becoming an essential component of modern data center design, supporting both sustainability goals and stronger integration with local communities.
