Water and Cooling as Emerging Constraints
Key Questions
Why is liquid cooling becoming mandatory for AI data centers?
Direct-to-chip liquid cooling is required to handle high-density AI workloads, with CoolIT's 15kW cold plates and NVIDIA's fanless systems leading adoption. Liquid cooling CAGR is projected at 18.2% through 2035 amid water constraints.
What companies are benefiting from the cooling technology boom?
ZutaCore raised $100M at $600M valuation; Modine saw 158% data center revenue growth with $4B reservations; and nVent reported $2.3B backlog. Vertiv, AAON, and EnerSys are highlighted as key cooling plays.
How are water constraints affecting data center projects globally?
Severe water shortages have impacted India's Visakhapatnam project and Malaysia's Johor hub, prompting Meta to use desalinated seawater cooling in India. UN reports now emphasize water and land impacts beyond carbon emissions.
What innovations address water use in data center cooling?
Microsoft claims near-zero water cooling while Ferveret’s immersion technology offers zero-water, 15% better efficiency. Texas now mandates closed-loop systems, and Amazon reports a 42% drop in water use to 0.12 L/kWh.
How are material and supply chain issues impacting cooling adoption?
Liquid cooling manifolds face steel-vs-plastic choices with a $3B market doubling; ASHRAE is evaluating polypropylene. NVIDIA’s reference design stops at facility walls, leaving external water and infrastructure challenges unresolved.
