IBM’s Liquid Cooling Play: How Big Blue is Shaping the $22B Data Center Energy Market in 2025

Industry Adoption: IBM’s Shift from Foundational Pioneer to an Ecosystem Enabler in Data Center Liquid Cooling

Between 2021 and 2024, International Business Machines Corporation (IBM) primarily leveraged its deep, historical expertise in liquid cooling to support its own high-value product lines and strategic research. With roots in water-cooling dating back to 1964, the company’s activity was characterized by integrated, high-performance applications. This included continuously evolving water-cooling for its Z-series mainframes, deploying specialized water-cooled QPACE supercomputers for scientific research in Germany, and investing in next-generation R&D like “Project Goldeneye,” a prototype “super-fridge” for future quantum computers. Partnerships with firms like VMware and Intel were geared toward enabling on-premises AI on IBM’s hardware, reinforcing a model where advanced cooling was intrinsically tied to the sale of its integrated systems. The strategy was one of internal excellence, applying its cooling prowess to maintain a competitive edge in niche, high-margin sectors like mainframes, HPC, and quantum R&D.

The period from 2025 to today marks a significant strategic inflection point. IBM has pivoted from being an integrated solutions provider to a foundational technology enabler for the entire data center ecosystem. This change is most clearly articulated in the Q3 2025 CFO statement, which positioned IBM as a “direct beneficiary” of hyperscaler AI investments, signaling a shift to a capital-light, IP-centric model. Rather than competing directly with infrastructure giants like Vertiv, IBM is now pioneering core technologies like microfluidics and two-phase cooling and proliferating them through a vast partner network. This includes hyperscalers (Microsoft, Google, AWS), hardware manufacturers (Lenovo, AMD), and component specialists (Danfoss). This “enabling technology” approach allows IBM to capitalize on a market projected to hit $22.57 billion by 2034, driven by AI workloads that now require 70-80% liquid cooling in new builds. The variety of 2025 partnerships—from co-developing quantum supercomputers with AMD to enabling Lenovo’s energy-efficient IT—demonstrates that IBM’s cooling IP is becoming a critical, horizontal technology layer across the entire industry, validating its long-term R&D investments as the market’s thermal challenges intensify.

Geography of IBM’s Liquid Cooling Initiatives

From 2021 to 2024, IBM’s liquid cooling activities were geographically concentrated in regions strategic to its core R&D and high-performance computing businesses. Germany emerged as a key hub, hosting both the water-cooled QPACE supercomputer project with research institutions and the landmark launch of IBM’s European Quantum Data Center in Ehningen in 2024. These projects demonstrated IBM’s focus on deploying its most advanced cooling systems to support cutting-edge scientific and quantum research within established European tech corridors. Similarly, the partnership with Japanese chipmaker Rapidus on 2-nanometer technology signaled a focus on Asia’s advanced semiconductor ecosystem. The geographic footprint was precise and tied to deploying IBM’s own premier technologies.

Since the beginning of 2025, the geographic landscape has broadened significantly, shifting from a few strategic hubs to a global, partner-led deployment model. The confirmation of deep partnerships with global hyperscalers like AWS, Google, and Microsoft means IBM’s cooling IP is now being implemented wherever these giants build new AI capacity worldwide. Concrete examples of this expansion include the partnership with Equinix in Markham, Ontario, Canada, to create a heat-reuse network—a novel application of data center thermal management. Furthermore, the collaboration with Clean Energy Capital to develop a solar farm for its Hursley, UK data center demonstrates a focus on integrated sustainability solutions in Europe. This shift indicates that IBM’s technology is no longer confined to its own data centers but is becoming a mainstream component of global digital infrastructure.

Technology Maturity of IBM’s Liquid Cooling Portfolio

In the 2021–2024 period, IBM’s portfolio showed a clear distinction between mature commercial offerings and forward-looking R&D. Water cooling for its Z-series mainframes and the deployment of water-cooled QPACE supercomputers represented fully commercial, scaled technologies that had been refined over years. These systems were a testament to IBM’s ability to deliver reliable, high-performance liquid cooling for enterprise and scientific workloads. In parallel, the company was investing heavily in future technologies. “Project Goldeneye,” a prototype dilution refrigerator for quantum computers, was in the advanced demo stage, while the development of a two-phase cooling system with ARPA-E was firmly in the R&D phase. The technology pipeline was robust but internally focused on enabling IBM’s next-generation platforms.

The period from 2025 to the present has been defined by market validation and the commercial scaling of technologies IBM pioneered. The key shift is that IBM’s innovations are now being commercialized by the broader market. For instance, microfluidics cooling, developed in IBM labs through projects like ICECool, is now being championed commercially by partners like Microsoft and Corintis. Direct-to-chip cooling, pioneered with Danfoss, is a mature, scaled solution demonstrating significant PUE reduction in the market. IBM is also using its own products, like the new Storage Scale System 6000 that holds 47PB in a single rack, as commercial proof-points for what its advanced thermal management makes possible. While foundational R&D continues, particularly in quantum cooling architectures with AMD and Cisco, the primary trend is the transition of IBM’s advanced cooling IP from its labs into the mainstream commercial ecosystem, validating its long-term technology bets.
