Spanish researchers turn wasted air currents into clean energy with groundbreaking innovation

In a recent article, Jason Deegan highlights that researchers at the Distance University of Madrid have developed a groundbreaking technology to capture energy from artificial air currents, a resource previously considered wasted. 

The key to this innovation is the use of compact, vertical turbines that can be seamlessly integrated into HVAC systems, capturing energy that would typically be lost.

These turbines, which generate 9 kW of power, are small, efficient, and easy to incorporate into existing infrastructure, making them an ideal solution for both residential and industrial use. This method provides a way to generate clean energy without requiring major system overhauls.

One of the first successful applications of this technology was at a data center in Colombia, where the turbines generated 468 MWh of energy annually. These turbines were paired with Liebert HPC-M coolers, featuring EC-FAN fans that produce vertical airflow essential for cooling the center's IT equipment. Now, these fans not only cool the equipment but also contribute to electricity generation.

The system's success lies in transforming HVAC airflow, once seen as a byproduct of the cooling process, into a valuable energy resource. This clever use of existing air currents offers exciting opportunities for energy efficiency.

The Tesup V7 turbines used in the project are lightweight and compact, allowing them to be easily integrated without disrupting the system's functionality. With six turbines in total, the system can generate 513.82 MWh of energy annually, ensuring a reliable and consistent power source.

Though installation incurs initial costs, the economic benefits are significant. The data center now produces 467.6 MWh per year, creating an energy surplus that can be redirected to the local power grid or used on-site. Over 20 years, the project offers an impressive internal rate of return of 50.69%, while reducing CO2 emissions by 300 tons annually.

In conclusion, this innovative solution offers a sustainable way to reduce energy consumption, lower carbon footprints, and enhance energy independence, paving the way for a greener future.
