HPE Turns Data Center Heat Into Power for Farms and Cities

A single data center can generate enough excess heat to warm entire neighborhoods, and now that energy is getting a second life instead of going to waste.

HPE's global advisory team has pioneered a heat reuse system that captures up to five megawatts of thermal energy from data centers and redirects it to farms, factories, and building campuses. The innovation, developed with partner Danfoss, turns what was once an environmental problem into a practical solution for communities.

The breakthrough comes as AI factories multiply worldwide, each one consuming enormous amounts of power and generating intense heat. Sue Preston, HPE's Vice President of Worldwide Advisory and Professional Services, says her team focuses on delivering technology solutions that also address sustainability challenges.

In Canada, HPE helped telecom company TELUS build its first AI factory powered entirely by renewable energy. The project supports Canadian startups and AI research while keeping environmental impact low.

Preston's team also uses liquid cooling systems that make heat capture more efficient. These systems prevent thermal waste while reducing the energy needed to keep massive server farms running.

The Ripple Effect

Beyond environmental wins, HPE is applying technology to human rights challenges. The company recently launched a pilot program with the Thai government and the Data Foundation Partnership to combat forced labor in supply chains.

The system uses data tracking to identify and eliminate forced labor practices, both in HPE's own supply chain and for customer companies. Preston calls it "technology for good" and says her team built the proof of concept with energy she's never seen before in her career.

The dual focus on sustainability and social responsibility reflects a broader shift in the tech industry. Companies are being asked to deliver more than fast infrastructure. Customers want partners who help them meet climate goals and ethical standards at the same time.

Preston says co-innovation with customers and partners makes the biggest difference. Rather than selling one-size-fits-all solutions, her teams work directly with organizations to design systems that match their specific challenges and values.

The heat reuse technology alone could transform how cities plan energy infrastructure. Imagine data centers becoming heat utilities for nearby schools, hospitals, and homes instead of just draining power from the grid.

Technology companies are finally treating their environmental footprint as an engineering problem worth solving, not just a cost of doing business.
