Austin-based tech firm chosen for UT-Arlington project on data center cooling dilemma
An Austin tech company is partnering with the University of Texas at Arlington to develop innovative methods for cooling chips in data centers. Accelsius, an Austin-based company focused on two-phase, direct-to-chip liquid cooling, was selected as a contributor to a federal project looking to develop a hybrid cooling method for use in data centers. Data centers are large facilities housing servers that deliver computing power for essential services, from emergency operations to smartphones. Most data centers use air circulation or liquid cooling systems, which consume significant energy and water, to prevent chips from overheating and enable continuous 24/7 operation.

"The government is actually concerned that as these chips get hotter, the architectures for cooling them won't keep up and therefore will impede progress on AI enablement, development and deployment," Accelsius CEO Josh Claman told the American-Statesman. Claman, who previously worked as an executive at Dell Technologies, launched his startup Accelsius three years ago, just before OpenAI's ChatGPT launched to the world. Claman said data centers have historically operated inefficiently, often shifting the extra energy costs of cooling onto tenants. He added that approximately 40% of the energy required to run these facilities 24/7 is wasted on cooling and overhead. "This was always sort of an issue that was near to my heart. Why can't we do this more efficiently?" Claman said. "Air is a terrible transport of heat, everyone knows that. If you have a 100 megawatt data center, you're wasting about 40 megawatts on cooling and overhead. That seems absurd. But it's been tolerated." These additional energy costs, the substantial strain on power grids and the significant water usage required to operate and cool data centers have been at the heart of community protests for several years. A recent report by Data Center Watch, a research organization that tracks data center opposition, found that about $64 billion in data center development nationwide has been stalled due to community pushback.

It'll likely be built anyway With water-based cooling, Claman says data centers can open themselves up to leaks and possibly expensive damage. Servers in data centers can be worth upwards of $400,000, meaning a rack can be work $3.5 to $5 million. Claman said Accelsius is looking to create hybrid cooling infrastructure. The company has two products on the market, with its second product, a multirack 250 kilowatt two-phase coolant distribution unit, having launched a few weeks ago and is being provided to UT-Arlington's ARPA-E project. "We're really confident the two-phase, direct-to-chip is going to be the technology that everyone centers on," Claman said. "So it's important that we get that sort of objective third party evaluation and experimentation. We want people to enter this market. We want to develop a global supply chain. We want to develop credibility around this technology. So for us, it was a really natural partnership. We really believe that if we're going to solve this issue around cooling chips, this is the sort of leading technology to get that done."

Accelsius Joins ARPA-E COOLERCHIPS Project to Advance Hybrid Cooling Technologies for the Data Center of the Future
AUSTIN, Texas--(BUSINESS WIRE)-- Accelsius, a leader in two-phase, direct-to-chip liquid cooling, has been selected as a key contributor to a U.S. Department of Energy (DOE) ARPA-E COOLERCHIPS project led by Professor Dereje Agonafer, a Presidential Distinguished Professor and Member of the National Academy of Engineering, at The University of Texas at Arlington. The project, 'Holistic Co-Design of Novel Hybrid Cooling Technology for the Data Center of the Future,' will develop a next-generation hybrid architecture that combines direct-to-chip evaporative cooling with air-based solutions such as rear door heat exchangers. Accelsius will support system-level testing by providing its proprietary MR250, a multi-rack, in-row, 250kW two-phase Coolant Distribution Unit (2P CDU), along with comprehensive integration support. The MR250 will be incorporated into the project's test infrastructure at the UT Arlington campus, with general availability planned for late 2025. 'The addition of Accelsius technology to our lab and project will improve our understanding and benchmarking of two-phase, direct-to-chip cooling as a practical and scalable option for growing rack densities,' said Professor Agonafer. 'We invite anyone attending the upcoming ITherm event to join us at the lab for an in-person tour and deeper understanding of the project and technologies involved.' The COOLERCHIPS (Cooling Operations Optimized for Leaps in Energy, Reliability, and Carbon Hyperefficiency for Information Processing Systems) program aims to transform how high-density data centers are cooled. The goal is to reduce total cooling energy consumption to less than 5% of a data center's IT load—while maintaining reliability and enabling next-generation high-density compute. 'It's great to see leaders like Dereje Agonafer and Richard Bonner working together to shape the future of two-phase cooling technology,' said Peter de Bock, program director at ARPA-E. 'Accelsius and The University of Texas at Arlington are advancing important work under the COOLERCHIPS program, and I'm excited to see the impact this collaboration will have on US leadership in next-generation data center efficiency.' 'It's an exciting opportunity to collaborate with fellow thermal experts from across the industry,' said Dr. Richard Bonner, chief technology officer at Accelsius. 'This project provides a bigger stage to showcase the meaningful advancements we've made in two-phase cooling and to push the envelope on what's possible for future data center efficiency.' About Accelsius Founded by Innventure, Inc. (NASDAQ:INV), Accelsius empowers data center and edge operators to achieve their business, financial and sustainability goals through advanced cooling solutions. The proprietary NeuCool platform provides best-in-class thermal efficiencies through a safe, two-phase liquid cooling system that scales from single racks to entire data centers.
