Uptime Institute emphasizes that liquid cooling remains niche in AI data centers, suited only for ultra-high-density setups. This insight helps engineers evaluate cooling options as AI compute demands intensify without overinvesting in specialized systems.

• Liquid cooling targets racks over 100 kW, while most AI workloads stay under 50 kW with air cooling
• Adoption rate in hyperscale facilities is below 5% for AI-specific deployments
• Implementation costs for liquid cooling range from $500,000 to $1 million per rack row
• Air cooling handles most setups under 50 kW effectively

Roland Berger’s report highlights how energy storage systems address power volatility in AI data centers, which is essential as AI workloads cause rapid demand spikes that strain grids and increase costs.

• AI training can cause power demand to fluctuate by 20-50% in seconds, risking outages
• Battery systems provide 50-200 MW of backup power for 15-60 minutes during peaks
• Roland Berger projects storage integration could reduce energy costs by 10-25% annually
• California and Texas lead with over 5 GW of data center storage deployments planned by 2025
• Lithium-ion batteries dominate, with 80% market share, followed by flow batteries for longer durations
• Report recommends hybrid setups combining storage with renewables for 99.99% uptime

In this Datacenter Dynamics interview, host James Radings speaks with Rajat Bagghdad, senior mechanical engineer at Arcadis, about current challenges in data center cooling systems. Data center engineers should watch to gain insights into deploying liquid cooling at scale and addressing operational hurdles in high-density environments.

• Liquid cooling technology is well-known, but the main challenge lies in its industrial-scale deployment for hyperscalers across multiple data centers.
• Hyperscalers need vendors and OEMs to supply the necessary liquid cooling infrastructure to meet deployment demands.
• Operators trained in air cooling must quickly learn liquid cooling while maintaining high uptime requirements.
• Design challenges include understanding interactions between servers and cooling systems in high-density AI factories where loads fluctuate rapidly.
• GPU workloads can spike every couple of seconds or microseconds, but cooling systems are not reactive enough to handle such variations.
• Engineers focus on stabilizing systems to provide continuous flow of cooling or chilled water, as chillers are not suited for rapid changes.

Federal agencies are gearing up to impose new regulations on data centers to curb their escalating energy demands and environmental footprint driven by AI growth. This development matters for data center engineers as it may reshape facility designs, operational efficiencies, and compliance requirements nationwide.

• EPA plans to establish efficiency standards targeting data centers power consumption
• Data centers account for 2-3% of US electricity use, expected to reach 8% by 2030
• DOE is collaborating on rules for carbon emissions, water usage, and grid reliability
• Regulations could mandate energy reporting for facilities over 100 MW starting in 2025
• Key states impacted include Virginia, Texas, and California with high data center concentrations
• Industry input from groups like the Information Technology Industry Council is being sought

A recent report analyzes the explosive growth of data centers in Virginia and Texas, detailing their outsized effects on regional power grids. Understanding these dynamics helps engineers plan for scalable, reliable electricity infrastructure amid rising AI and cloud demands.

• Virginia data centers consumed 5,000 MW in 2023, representing 25% of Dominion Energy’s total load
• Texas saw data center capacity reach 2,500 MW by mid-2024, driven by expansions in Dallas and San Antonio
• Projections indicate Virginia’s data center power needs could hit 10,000 MW by 2030
• ERCOT forecasts 15 GW of additional load growth in Texas from data centers over the next decade
• Both states face transmission upgrades costing billions, including $5 billion in Virginia projects
• Report highlights policy responses, such as Texas incentives for on-site generation

Marshall County in Indiana has approved a permanent ban on data centers, effective immediately, potentially shifting development focus to more permissive regions. This move highlights escalating local regulatory hurdles for data center expansions amid concerns about infrastructure strain.

• Marshall County Commissioners approved the ban in a unanimous vote during their latest meeting
• Ban prohibits all new data center constructions and expansions within county limits
• Existing facilities remain operational but face restrictions on modifications or upgrades
• Decision driven by local worries over high water consumption, energy demands, and noise pollution
• Effective immediately, with no grace period for pending project applications
• Similar restrictions under discussion in adjacent counties like Kosciusko and Fulton
