LOS ANGELES--(BUSINESS WIRE)--Sep 9, 2025--

Capstone Green Energy Holdings, Inc. (the "Company” or “Capstone”) (OTCID: CGEH) and Capstone Green Energy, LLC, a leader in microturbine energy systems, and Microgrids 4 AI, Inc. (“MG4AI”), a developer of modular AI infrastructure solutions, today announced the signing of a strategic Memorandum of Understanding (MOU) to collaborate on delivering sustainable, scalable, and resilient infrastructure for the artificial intelligence (AI) data center market.

MG4AI architects and delivers modular turnkey AI-ready infrastructure for edge data centers under 20MW, enabling enterprises, sovereign customers, and innovators to deploy GPU-intensive compute environments faster, more securely, and independent of traditional utility constraints. By integrating localized, grid-independent microgrids with advanced liquid cooling, MG4AI helps customers bypass multi-year grid upgrade delays, reduce operating costs, and achieve greater resiliency in powering AI innovation.

Under this strategic collaboration, MG4AI’s modular infrastructure will be paired with Capstone’s ultra-low-emission, high-cycle efficiency, and low-maintenance microturbine technology to deliver grid-independent, distributed AI infrastructure. The collaboration will integrate Capstone’s proven Combined Cooling and Power (CCP) systems with MG4AI’s containerized compute pods, enabling rapid deployment, reduced power and cooling costs, and unmatched reliability in mission-critical AI workloads.

“Capstone’s advanced distributed power platform is purpose-built for the next wave of digital infrastructure,” said Vince Canino, President and CEO of Capstone Green Energy. “Artificial intelligence is one of the most energy-intensive applications and disruptive workloads of our time. By aligning Capstone’s technology with MG4AI’s modular compute architecture, we are setting a new standard for speed, efficiency, and sustainability in AI infrastructure deployments.”

“The future of AI will not be built on yesterday’s data centers. It demands innovative new infrastructure – where power, liquid cooling, and compute converge as one, a complete kit,” said Ken Kajikawa, CEO of MG4AI. “Together with Capstone, MG4AI is creating a new blueprint for AI: sovereign, sustainable, and infinitely scalable (140kW today and scaling to 600kW per rack). We’re not just keeping pace with the AI revolution; we’re building the new foundation that makes next-generation AI infrastructure possible.”

Capstone’s microturbine-based systems provide clean, reliable on-site power and are designed to integrate seamlessly with advanced cooling technologies such as a Capstone Engineered Equipment Package (EEP), including chillers, dry coolers, and pumping packages (a BESS when needed). By combining this capability with MG4AI’s expertise in edge data center compute infrastructure, the strategic collaboration aims to deliver rapid deployable solutions that address the growing energy and performance demands of AI workloads.
