Researchers from the Distance University of Madrid (UDIMA) and Mision Critica-Data Center have made a groundbreaking discovery that could revolutionize the energy industry. By harnessing the airflow produced by data center cooling fans, they have developed a method to generate electricity, effectively turning waste wind into a valuable renewable resource.

Typically, data centers expel warm air outdoors as part of their HVAC systems. This constant airflow, often overlooked, represents a significant untapped source of energy. The UDIMA-Mision Critica team utilized vertical axis wind turbines to capture this artificial wind and convert it into electricity. In a case study of a Colombian data center, six turbines were installed atop chillers, successfully generating more electricity than was consumed by the fans themselves.

The researchers found that this innovative approach not only provides a sustainable energy solution but also offers significant economic and environmental benefits. The system generates a positive cash flow within three years and boasts an impressive internal rate of return of 50.69%. Additionally, it reduces CO2 emissions by approximately 300 metric tons annually.

The study’s authors believe that this method can be applied to other industries with similar airflows, such as manufacturing facilities and large commercial buildings.
