CleanSpark and Submer have entered a non‑binding framework to evaluate opportunities for AI data‑center expansion across North America, combining CleanSpark’s low‑cost power and land assets with Submer’s liquid‑cooled modular technology.

Under the framework, CleanSpark will select sites, develop and operate AI‑centric campuses, while Submer will provide design, construction, and cooling solutions. The partnership builds on CleanSpark’s vertically integrated model and rapid site‑development experience from its Bitcoin mining operations.

CleanSpark’s portfolio already exceeds 1 GW of power and data‑center capacity, with a pipeline of more than 2 GW, and the collaboration aims to scale this capacity to meet growing AI demand. Submer’s liquid‑cooling is expected to improve energy efficiency and reduce operating costs, supporting the deployment of high‑density AI compute at scale.

The announcement follows CleanSpark’s recent appointment of Jeffrey Thomas as Senior Vice President of AI Data Centers, underscoring the company’s commitment to diversifying beyond Bitcoin mining. Submer’s CEO Patrick Smets highlighted the partnership as a pivotal step toward scaling AI infrastructure globally.

The move aligns with a broader industry trend of cryptocurrency miners expanding into AI data‑center services, as other firms such as Core Scientific, Iris Energy, and Riot Platforms pursue similar diversification strategies.
