CleanSpark, a U.S.-based Bitcoin miner and data center developer, has named Submer, a European leader in modular and liquid-cooled data center technology, as its first strategic partner for the company’s expanding portfolio of AI-focused infrastructure projects across North America.
The partnership aims to combine CleanSpark’s large-scale energy and site development capabilities with Submer’s high-efficiency cooling and modular deployment systems to create a new class of sustainable, high-performance AI data centers.
The collaboration represents an early-stage framework agreement under which both companies will explore joint opportunities in AI infrastructure development. CleanSpark will focus on identifying, designing, and operating large AI campuses powered by renewable and distributed energy sources, while Submer will provide its expertise in immersion cooling, prefabricated data center modules, and scalable construction solutions. Together, the two firms plan to build an integrated platform that merges power generation, compute infrastructure, and AI service delivery into a single vertically aligned ecosystem.
“Submer has established itself as one of the most advanced and forward-thinking AI infrastructure firms in the industry,” said CleanSpark CEO and Chairman Matt Schultz. “By combining our energy and land portfolio with Submer’s state-of-the-art AI deployment and liquid-cooling expertise, we are positioned to deliver AI capacity at gigawatt scale – faster, cleaner, and more efficiently than traditional approaches. This relationship perfectly aligns with our vision of transforming CleanSpark’s infrastructure platform into the backbone of the next era of intelligent computing.”
Sustainable Data Center Design
Founded in 2015, Submer has become a global reference in sustainable data center design, offering end-to-end solutions from immersion-cooling systems and power modules to fully prefabricated data center builds. Its technology enables high-density compute environments with drastically reduced power consumption and water use compared to traditional air-cooled facilities. As demand for large-scale AI and high-performance computing infrastructure accelerates, Submer’s modular approach allows operators to deploy capacity quickly while minimizing environmental impact.
Patrick Smets, CEO of Submer, described the collaboration as a strategic move toward redefining how AI infrastructure is designed and delivered. “CleanSpark’s unmatched expertise in site development, power strategy, and large-scale operations, combined with Submer’s ability to design and deploy high-density AI environments rapidly and efficiently, creates a new blueprint for sustainable, high-performance AI compute at scale,” said Mr. Smets. “Together, we’re building the industrial foundation for the Age of Intelligence and the infrastructure that will sustain it.”
CleanSpark, traditionally known for its energy generation and management operations, has in recent years pivoted toward becoming a vertically integrated developer of digital infrastructure. Its expansion into AI data centers builds on its experience with power optimization and its ability to rapidly construct and operate large sites. The company aims to capitalize on the global surge in demand for compute capacity driven by AI model training, data analytics, and emerging agentic AI applications.
Jeffrey Thomas, CleanSpark’s Senior Vice President of AI Data Centers, emphasized that technical partnerships such as this one are critical to maintaining speed and reliability in large-scale deployments. “Submer has already secured approvals for its designs under leading reference architectures,” said Mr. Thomas. “Working with Submer accelerates our capability to scale at pace, and we expect to conclude definitive agreements in the coming weeks.”
The companies are currently operating under a non-binding framework agreement but have signaled intentions to formalize their partnership soon. If finalized, their collaboration could mark a major step toward establishing a new model for AI data center development – one that integrates sustainable power generation, modular architecture, and next-generation cooling technologies to meet the escalating energy and performance demands of artificial intelligence infrastructure in North America and beyond.
