Naba Alsaha and Strataphy Partner to Launch One of Saudi Arabia’s First Geothermal-Cooled Hospitals

In a pioneering step for sustainable healthcare infrastructure, Naba Alsaha Hospital, a leading Saudi healthcare group, has partnered with clean cooling innovator Strataphy to deploy advanced, subsurface-powered cooling systems for its new hospital complex in Riyadh, currently under construction.

“This project highlights how geothermal technology can meet the strict reliability and operational demands of the healthcare sector,” said Ahmed Alhani, COO of Strataphy. “Hospitals require uninterrupted cooling performance around the clock. With our CAS model and subsurface technology, we’re able to deliver that performance while significantly reducing grid impact and carbon emissions.”

Saudi Arabia has more than 2,300 healthcare facilities across the Kingdom. With each facility requiring on average 1.5 megawatts-thermal (MW-th) of cooling capacity, the national healthcare sector represents a total thermal demand of approximately 3.45 gigawatts-thermal (GW-th). This places immense strain on the power grid and creates a clear opportunity for cleaner, more efficient solutions.

At the heart of the system is Strataphy’s PrimeLoop—a patent-pending geothermal hybrid architecture that uses subsurface temperatures to deliver continuous and efficient building cooling. Unlike traditional HVAC systems, which rely on electricity-intensive compressors and degrade in performance during high ambient temperatures, PrimeLoop operates silently and consistently, delivering a Coefficient of Performance (COP) over 5, more than double that of conventional methods.

The solution is offered through Strataphy’s Cooling as a Service (CAS) model—turning cooling from a costly CapEx decision into a monthly operating service. Strataphy handles design, drilling, installation, and long-term operations and maintenance, with clients only paying for actual cooling used. This removes technical and financial risk while improving ESG outcomes.

“As demand for high-performance medical infrastructure grows, we’re proud to be among the first hospitals in the Kingdom to adopt this innovative, sustainable approach,” said Nayef Al-Jishi, Business Development Manager at Naba Alsaha Hospital. “For us, it’s about delivering long-term value to patients, operators, and the national grid. This partnership with Strataphy reinforces our commitment to future-ready, resilient, and environmentally aligned healthcare facilities.”

“This collaboration reflects a broader transformation underway across the Kingdom,” concluded Ammar Alali, CEO of Strataphy. “The healthcare sector—with its 24/7 operational needs—is ideally suited to lead the geothermal cooling transition. We’re proud to help power that shift and demonstrate how clean infrastructure can meet both performance and sustainability goals.”
