Reimagining Data Center Energy Utilization
Putting heat to work
The data center boom is heating up—literally. From hyperscale data centers to modular AI clusters, every leap in compute power brings with it the same quiet cost: heat. A lot of it. And while processors evolve at breakneck speed, the their power intensity continues unabated.
Separation Anxiety
Data center operators want to dedicate as much power as possible to compute. However, the most modern data centers dedicate 10-15% (40-50% for older designs) of their limited power towards cooling. - just moving heat away from chips and out of the building. Cooling is inextricably linked from compute and serves as a boat-anchor on the economics of data centers.
Improved efficiency frees more electrical capacity for compute resources. The additional compute resources increases the amount of cooling that is required. Efficiency doesn’t' come for free and can greatly increase capital expenses and maintenance costs. Though there are many players that appear willing to spare no expense, sound business economics must prevail in the long-run for the current adoption rate to continue.
A Complex Problem
The data center industry tracks Power utilization efficiency (PUE) for each facility. The global average PUE has been flat for a decade. Large hyperscalers are able to deploy the best in energy efficiency and reach world class PUEs - but a cost that can only be afforded by their online advertising or cloud computing businesses.
Even the best facilities need a drastic rethink given the capital infrastructure and maintenance required for the most advanced systems.
Other high-heat industries have found ways to turn excess heat into productive use. In petrochemical and manufacturing, for example, heat reuse is foundational. The problem? Those industries rely on high-temperature processes—where steam can be generated for power or otherwise directly reused.
Data centers run much cooler (< 50 C) with rudimentary coolant mediums (air, water, dielectric fluids). Data centers are just cool enough to make most conventional heat recovery systems impractical (> 100 C). They operate in a frustrating thermal no-man’s-land where conventional cogeneration is unfeasible.
Captis Will Transform Your Data Center
We build devices that turn waste heat into usable electrical power. Our modules are compact, cost-effective, and designed for flexible deployment across different data center configurations. And because the laws of thermodynamics exist, they also reduce the amount of heat required to cool.
We want to transform the data center's biggest waste product - heat - into its most valued input - electricity - at an affordable price.
