An ambitious vision is unfolding under the aegis of the U.S. Department of Energy’s ARPA-E COOLERCHIPS initiative, a project that aims to transform the energy landscape of data centers. At the heart of this revolution are novel cooling technologies designed to slash cooling energy expenditures to a mere 5% of a typical data center’s IT load.
Prototypes Spark a Revolution
Remarkably, within just 15 months, the COOLERCHIPS teams have crafted prototypes tested on real servers. These models showcase dazzling performances, especially under extreme conditions like those in the sweltering desert heat of Phoenix, Arizona. There, prototypes run racks exceeding 120 kW, making a formidable case for reducing cooling energy by 90% compared to current methods. This monumental leap means that a colossal 95% of energy is now retained for processing power and computing.
Pioneering Startups and Strategic Acquisitions
This initiative has not only birthed new technologies but also new startups. Novolinc, ThermalPixels, and Chipadd have sprung from the program, each pushing the boundaries of what’s possible with innovative cooling solutions. Flex’s acquisition of Jetcool underscores the program’s commercial viability, while other teams secure significant funding, propelling the industry forward with relentless vigor. Significant demonstrations by consortia like Omnicool, comprised of industry behemoths NVIDIA and Vertiv, have cemented their place as key players, showcasing an award-winning two-phase cooling system.
Fostering Innovation and Leadership
The variety of solutions emerging from COOLERCHIPS—encompassing single-phase, two-phase, immersion, and direct-to-chip cooling—are more than just technological feats. They herald a shift in system reliability, design engineering, and economics, positioning the U.S. as a leader in data center infrastructure. This reimagined ecosystem suggests that chips are merely 1% of the landscape, with the real opportunity lying in the supporting hardware that requires innovation.
A Vision for the Future
The path forward in AI computing presents daunting challenges. Traditionally complex systems could now lean towards an electrochemical model, creating a robust, DC-powered solution closely integrated with the chip, potentially offering endless power without reliance on conventional transformers.
Harnessing Waste Heat for a Sustainable Tomorrow
Another striking concept explored at the ARPA-E Energy Innovation Summit is the potential for carbon-negative and water-positive data centers. By efficiently elevating waste heat temperatures, data centers could, in theory, recycle that energy to extract carbon and water from the atmosphere. Such a transformation could see data centers contributing to carbon reduction rather than emission.
A Diverse Energy Palette
Looking ahead, powering AI and data centers will likely employ a varied menu of energy sources—from solar and wind to cutting-edge nuclear microreactors and traditional generators—optimizing for cost and availability in different locales.
The Key Takeaway
COOLERCHIPS is more than an innovation project; it’s a bold leap toward sustainable energy usage in computing infrastructure. By championing pioneering technologies and fostering a landscape where chips operate cooler, more efficiently, and with reduced environmental impact, the initiative not only sets technological benchmarks but also blazes a path for a more sustainable digital future.

These refer to the phases of matter (liquid or gas) through which heat is dissipated. Two-phase cooling often involves boiling a liquid into vapor to disperse heat efficiently.
– Direct-To-Chip and Immersion Cooling:
Direct-to-chip cooling delivers cooling directly to the source of heat—particularly useful for high-performance computing environments. Immersion involves submerging components in non-conductive liquid to uniformly remove heat.
2. Energy Efficiency:
– Prototypes developed under the COOLERCHIPS initiative have achieved a 90% reduction in cooling energy needs. This allows 95% of energy to be directed towards processing power, significantly enhancing computational efficiency.
3. Novel Materials and Design:
– New startups like Novolinc, ThermalPixels, and Chipadd have pioneered unique materials and designs as part of their cooling technologies, demonstrating potential in scalable manufacturing and deployment.
Market Impact and Industry Trends
– Strategic Partnerships and Acquisitions:
The acquisition of cooling tech company Jetcool by Flex illustrates significant commercial interest and confidence in these transformative technologies. These moves are likely to spur further investments in data center efficiency.
– Eco-Friendly Data Centers:
The potential for carbon-negative and water-positive data centers aligns with global efforts to mitigate climate change by reducing carbon footprints. Elevating waste heat to higher temperatures for energy reuse is a step toward sustainability.
Real-World Use Cases and Benefits
