Barcelona, Spain – October 28, 2025 – Submer, a global leader in liquid-cooling and sustainable datacenter solutions, has been selected by CleanSpark, Inc. (Nasdaq: CLSK), America’s Bitcoin Miner®, as its first strategic partner for AI datacenter expansion across North America.

The collaboration combines CleanSpark’s gigawatt-scale energy and site portfolio with Submer’s liquid-cooling technology, design, and integration expertise to deliver AI-ready, high-performance infrastructure that meets the world’s accelerating demand for intelligent compute.

Patrick Smets, CEO of Submer, said:

“This collaboration represents a pivotal step toward scaling AI infrastructure globally. CleanSpark’s unmatched expertise in site development, power strategy, and large-scale infrastructure delivery and 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. Together, we’re building the industrial foundation for the Age of Intelligence and building the infrastructure that will sustain it.”

As CleanSpark evolves from a pure-play Bitcoin miner to a leader in AI-ready infrastructure, this partnership represents a new model for power-efficient, sustainable AI deployment. Together, Submer and CleanSpark are developing a full-stack infrastructure platform that integrates power generation, datacenter construction, and AI service delivery – enabling faster, cleaner, and more scalable capacity growth.

Jeffrey Thomas, CleanSpark’s Senior Vice President of AI Datacenters, added:

“Working in conjunction with accomplished technical partners is critical for successful tenant and customer relationships. Submer already has received approvals for its designs for leading reference architectures. Working with Submer accelerates our capability and ability to scale at pace, and we look to conclude definitive agreements in the coming weeks.”

Power and Technology, Combined

The partnership leverages CleanSpark’s 3 gigawatts of U.S. land and power assets under development and Submer’s end-to-end capabilities – spanning liquid-cooling solutions, power and integration modules and full-facility design – to deploy AI capacity with unmatched efficiency and sustainability.

Initial projects will focus on North America, with potential expansion across Europe, the Middle East and India, supporting the growing ecosystem of hyperscalers, hardware providers, and sovereign compute initiatives looking for turnkey, sustainable AI campuses.

Sustainable Compute at Scale

Submer’s technology and advisory offering enables dramatic improvements in energy efficiency, density and water conservation, making it possible to scale AI infrastructure responsibly. This partnership sets a new standard for how AI infrastructure is designed, built, and operated – combining intelligence and sustainability at gigawatt scale.
