Soluna and KULR Technology Group Announce 3.3 MW Hosting Partnership at Project Sophie

Soluna’s first treasury-focused partnership signals a broadening customer base

ALBANY, N.Y.--(BUSINESS WIRE)--Soluna Holdings, Inc. (“Soluna” or the “Company”) (NASDAQ: SLNH), a developer of green data centers for intensive computing applications, today announced a new hosting partnership with KULR Technology Group, Inc. (“KULR”) (NYSE American: KULR), a Bitcoin+ treasury company that builds a portfolio of frontier technology businesses ranging from high-performance energy systems to AI Robotics.

Under this agreement, Soluna will operate approximately 3.3 MW of Bitcoin mining capacity for KULR at its Project Sophie facility in Kentucky. The exciting partnership marks the first time Soluna has partnered with a Bitcoin treasury-focused company, expanding the Company’s customer base beyond traditional Bitcoin miners and hyperscalers.

“This partnership represents a new chapter in how we serve the market,” said John Belizaire, CEO of Soluna.“ Treasury companies like KULR are increasingly seeking sustainable, high-performance computing infrastructure to diversify their digital asset strategies. We’re proud to pioneer a flexible hosting model that meets this evolving demand.”

The agreement reflects Soluna’s strategy to adapt its renewable-powered hosting model to meet the developing demand profiles of Bitcoin mining and adjacent industries.

“This collaboration supports KULR’s commitment to strategic innovation in digital asset management,” said Michael Mo, CEO of KULR Technology Group. “Partnering with Soluna allows us to engage in Bitcoin mining through a renewable, reliable, and operationally efficient framework.” Mo continued, “This is only the beginning. As KULR expands beyond Bitcoin mining and migrates into Battery Backup Unit (‘BBU’) solutions, Soluna stands out as the ideal partner for future projects focused on sustainable, low-cost AI data center hosting powered by stranded renewable energy."

As per the BBU Market analysis conducted by Custom Market Insights in July 2025, the global BBU Market is expected to grow from 29.22 billion USD in 2025 to 43.64 billion USD by 2034.

The 3.3 MW deployment at Project Sophie is expected to commence operations in Q4 2025, further strengthening Soluna’s leadership in sustainable computing infrastructure.

Under the partnership, KULR will leverage Soluna’s operational and market expertise to purchase, service, and manage all activities associated with its fleet of mining hardware over the life of the contract. Through this new “Bitcoin Mining Lease” structure, Soluna will deliver guaranteed hashrate and uptime targets to KULR on a daily and monthly basis.

We believe that as more established companies like KULR explore Bitcoin as part of their treasury strategy, Soluna’s model offers a mutually beneficial pathway to guaranteed hashrate without the operational complexity of mining. This partnership supports KULR’s Bitcoin Treasury Accumulation Strategy, announced earlier this year, in which KULR committed up to 90% of its surplus cash reserves to Bitcoin. Through its new hosting framework, Soluna empowers Bitcoin+ companies such as KULR to tap into the benefits of Bitcoin mining while avoiding the common challenges of market volatility and legacy infrastructure constraints.
