AI will drive greater than 50% of worldwide knowledge heart capability and greater than 70% of income alternative, in accordance with Omdia’s Analysis Director for Digital Infrastructure Vlad Galabov, who mentioned large productiveness features throughout industries pushed by AI will gasoline this development. Talking throughout Information Heart World 2025’s analyst day, Galabov made quite a lot of different predictions concerning the trade:
- NVIDIA and hyperscalers’ 1 MW-per-rack ambitions in all probability gained’t materialize for an additional couple of years till engineering innovation catches as much as energy and cooling calls for.
- By 2030, over 35 GW of information heart energy is predicted to be self-generated, making off-grid and behind-the-meter options now not elective for these seeking to construct new knowledge facilities, as many utilities wrestle to ship the required energy.
- Information heart annual capital expenditure (CAPEX) investments are anticipated to succeed in $1 trillion globally by 2030, up from lower than $500 billion on the finish of 2024.
- The strongest space for CAPEX is bodily infrastructure, reminiscent of energy and cooling, the place spending is growing at a fee of 18% per yr.
“As compute densities and rack densities climb, the funding in bodily infrastructure accelerates,” Galabov mentioned. “We anticipate a consolidation of server rely the place a small variety of scaled-up techniques are most popular to a scaled-out server technique. The price per byte/compute cycle can also be lowering.”
Information heart energy capability explodes
Galabov highlighted the explosion AI has triggered in knowledge heart energy wants. When the AI wave started in late 2023, the put in capability of energy in knowledge facilities worldwide was lower than 150 GW. However with 120 kW rack designs on the rapid horizon, and 600 kW racks solely about two years away, he forecasts almost 400 GW of cumulative knowledge heart capability by 2030. With new knowledge heart capability additions approaching 50 GW per yr by the top of the last decade, it gained’t be lengthy earlier than half a terawatt turns into the norm.
However not everybody will survive the wild west of the AI and DC market. Many startup DC campus developments and neoclouds will fail to construct a long-term enterprise mannequin, as some lack the experience and enterprise savvy to outlive. Don’t concentrate on a single supplier, Galabov cautioned, as some are prone to fail.

AI drives liquid cooling innovation
Omdia’s Principal Analyst Shen Wang laid out the cooling repercussions of the AI wave. Air cooling hit its restrict round 2022, he mentioned. The consensus is that it may well ship as much as 80 Watts per cm2, with just a few suppliers claiming they’ll take air cooling greater.
Past that vary, single-phase direct-to-chip (DtC) cooling — through which water or a fluid is taken to chilly plates that sit immediately on prime of pc chips to take away warmth — is required. Single-phase DtC can go as excessive as 140 W/cm2.
“Single-phase DtC is one of the best ways to chill chips proper now,” Wang mentioned. “By 2026, the brink for single-phase DtC will probably be exceeded by the newest racks.” That’s when two-phase liquid cooling ought to start to see a ramp-up in adoption charges. Two-phase cooling runs fluids at greater temperatures to the chip, inflicting them to show to vapor as a part of the cooling course of, thereby growing cooling effectivity.
“Superior chips within the 600 watt and above vary are seeing the heaviest adoption of liquid cooling,” Wang mentioned. “By 2028, 80% of chips in that class will make the most of liquid cooling, up from 50% immediately.”
