Danish Data Center Heats Homes With Server Waste

A Meta data center in Odense, Denmark, is pioneering a unique approach by redirecting its waste heat into the local community's heating system. While most data centers vent this energy, the Odense facility captures it. The low-grade heat from servers is absorbed by water from the municipal district-heating network. This water then moves to a plant with heat pumps that elevate its temperature to between 70 and 75°C.

This process makes the water suitable for warming over 12,000 homes annually, providing an estimated 215,000 megawatt-hours of recovered energy each year. This large-scale implementation of heat pump technology is significant. The success of this project hinges on Odense's existing, extensive district-heating infrastructure, which is essential for efficient heat transfer over distances.
