- Soluna Holdings, Inc. is a digital infrastructure company specializing in transforming surplus renewable energy from wind, solar, and hydroelectric power plants into high-performance computing resources. The company operates modular data centers co-located with renewable energy facilities to support compute-intensive applications such as cryptocurrency mining, generative artificial intelligence (AI), and scientific computing. Soluna offers core products and services across three segments: cryptocurrency mining through proprietary software and hardware; data center hosting providing electrical power, network connectivity, and colocation services for third-party Bitcoin miners and AI workloads; and high-performance computing (HPC) services supporting generative AI workstreams including training and fine-tuning large language models. The company leverages its proprietary MaestroOS software to optimize efficiency, sustainability, and profitability while integrating grid services that utilize surplus renewable energy to stabilize power networks. Founded in 1961 and headquartered in Albany, New York, Soluna operates primarily in the United States and through subsidiaries including Soluna Callisto Holdings, Inc., Soluna Digital, Inc., and others.
Recent major developments include the successful closing of a scalable $100 million credit facility with Generate Capital in 2025, which supports refinancing and expansion of their data center projects and accelerates growth in the AI market. The company secured additional capital from investors such as Galaxy Digital and Spring Lane Capital, enhancing its renewable computing capacity beyond 1 gigawatt. Construction began on Project Kati 1, a wind-powered data center in Texas, with Galaxy Digital committing to deploy 48 MW out of a total 83 MW at this site, marking Soluna's largest hosting deployment to date. The company also reached a settlement with NYDIG, clearing the path for further growth and partnerships. Operationally, Soluna expanded its Project Dorothy 2 Bitcoin mining site to full capacity, contributing to record Q3 2025 financial results including a 37% sequential revenue increase and improved adjusted EBITDA. These advancements demonstrate Soluna's strategic focus on scaling renewable-powered computing infrastructure for Bitcoin mining and AI applications while enhancing shareholder value through capital efficiency and institutional partnerships.
