Strategies for Refrigerating AI Data Centres in Desert Environments

In the heart of the desert, where water is a precious resource, Middle Eastern AI data centers are adapting to their unique environment by implementing advanced cooling methods and water reuse strategies. These innovations are not only shaping the region's technological growth but also mitigating the exacerbation of existing water scarcity.

Two-phase immersion cooling systems are one such solution, submerging AI hardware in specialized liquids that absorb heat more efficiently than air cooling. This method allows significant water recycling, lowering overall water consumption. However, these systems are costly and have operational challenges.

Another approach is the integration with desalination plants. New data centers are planning to connect with desalination infrastructure, using waste heat from computations to improve energy efficiency and water recycling, helping alleviate competition for limited freshwater.

Recycled or non-potable water is also being explored for cooling purposes. Countries like the UAE are leveraging local expertise in water reuse to preserve potable water supplies.

However, it's essential to strike a balance between water savings and energy efficiency. Alternative cooling methods that save water may increase electricity usage and indirectly consume more water in power generation.

Cooling at scale is the limiting factor for data centers in the Middle East due to the region's hot temperatures, as highlighted by Mohammed Soliman, director of the strategic technology program at the Middle East Institute.

The Middle East, currently undergoing an economic renaissance driven in part by artificial intelligence, is showing a growing interest in increasing the efficiency of data centers. Companies operating data centers in the region, such as Google, are already taking steps to reduce their water consumption. In 2024, Google's data centers used 6.1 billion gallons of water, a 17% increase from 2022.

Thar Casey, CEO of AmberSemi, emphasized that Gulf countries are showing tremendous interest in increasing the efficiency of data centers. Newer data centers in the Middle East might be paired with existing desalination plants to use the heat generated by the centers rather than wasting it.

Innovations in cooling technology could make the Middle East the most optimal place to "bring chips online". The cooling sector was worth about $11 billion as of 2025 and is expected to reach $24 billion by 2032.

The UAE, which recently announced plans for a 5GW UAE-US AI Campus, is showing a particular affinity for lessening the environmental footprint of data centers while maximizing the newest cooling technology.

The film "Lawrence of Arabia" famously features a line from Omar Sharif's character, Sherif Ali, emphasizing the importance of water supplies in the desert. Today, this sentiment rings truer than ever as the region navigates the challenges of AI data center development while preserving its precious water resources.

11 out of the 17 most water-stressed countries in the world are located in the Middle East and North Africa. The Gulf region could unlock a world-class AI ecosystem by cracking the cooling challenge for data centers. AI data centers require huge amounts of power and cooling, which cannot be achieved with small fans.

In conclusion, Middle Eastern AI data centers are embracing innovative cooling methods and water reuse strategies tailored to their arid environment to reduce freshwater consumption and limit further strain on scarce water resources, reflecting a growing commitment to sustainable technology development in water-stressed regions.
