UL Solutions flags rising safety risks as AI data center power densities climb
ULS•UL Solutions says rising power density in AI data centers is increasing interconnected infrastructure risks. Rack power density could approach 1 MW by 2027-2028, up from approximately 10 kW in 2020.
1. Rising power demands
UL Solutions’ analysis says rising power density is creating interconnected risks to AI data center operations. Industry road maps suggest rack power density could approach 1 MW by 2027-2028, compared with approximately 10 kW in 2020.
2. Cooling and safety risks
Air cooling struggles beyond approximately 25-30 kW per rack, prompting adoption of liquid cooling, which introduces leakage and material-compatibility risks. UL Solutions says component compliance alone may not ensure system safety, making integrated infrastructure evaluation important to reliability and avoiding costly redesigns or deployment delays.
