Capstone Green Energy and Microgrids 4 AI Launch 800 VDC Microturbine Solution to Power Next-Generation AI Infrastructure
Capstone Green Energy Holdings, Inc., along with its subsidiaries (collectively, “Capstone” or the “Company”) (OTCQX: CGEH), a leading innovator in clean, low-emission microturbine energy systems and advanced clean technology solutions, has announced a strategic collaboration with Microgrids 4 AI, Inc. (“MG4AI”), a developer of modular, AI-ready data center infrastructure. Together, the companies unveiled an 800-volt direct-current (VDC) microturbine and compute-engineered equipment package designed to power the next generation of artificial intelligence (AI) infrastructure. The announcement was made at Data Center World Asia on October 9 and positions both Capstone and MG4AI at the forefront of the global push toward high-efficiency, scalable energy solutions for AI workloads.
The new 800 VDC microturbine system reflects a major step forward in energy delivery for high-performance computing environments. It directly addresses the growing demands of megawatt-scale AI workloads and next-generation data center operations, aligning with the industry transitions highlighted by NVIDIA and other leading data center infrastructure providers. This solution is particularly relevant as AI applications become increasingly complex, requiring denser compute resources and more efficient power delivery systems.
A Technological Leap in Power Efficiency
Capstone’s 800 VDC natural gas microturbine builds on the company’s proven inverter-based power electronics technologies. Designed for compatibility with upcoming Kyber and Rubin Ultra platforms, the system eliminates the need for multiple AC/DC conversion stages that are common in conventional data center power architectures. By doing so, the solution significantly reduces the copper mass required for power delivery—by up to 45%—and enhances overall energy efficiency by as much as 5% when compared to traditional 54-volt systems.
“This evolution in AI infrastructure fundamentally challenges conventional energy delivery norms,” said Vince Canino, President and CEO of Capstone Green Energy. “AI racks today already draw over 200 kW and are rapidly approaching 1 MW per rack. Our 800 VDC microturbine is engineered to meet these demands, providing clean, reliable, redundant, and direct high-voltage DC power tailored for the next generation of AI Factories. This is an exciting moment in the digital age, where energy solutions are no longer just about supply—they are about enabling transformative computational performance.”
Scalable Solutions for Sovereign AI and Sustainable Energy
Through their partnership, Capstone and MG4AI are integrating the 800 VDC microturbine with MG4AI’s modular, liquid-cooled data center kits, creating turnkey, grid-independent “AI Power Blocks.” Each AI Power Block delivers a unified system that integrates power, liquid cooling, and compute, enabling rapid deployment across diverse operational scenarios. These systems are designed to scale efficiently, from smaller edge deployments under 20 MW to expansive AI giga-campuses exceeding 1 GW, supporting sovereign, enterprise, and commercial AI environments.
Ken Kajikawa, CEO of Microgrids 4 AI, emphasized the strategic importance of the collaboration: “The AI Factory requires infrastructure that is smarter, faster, and more efficient than ever before. By integrating Capstone’s 800 VDC microturbine and its Engineered Equipment Package (EEP)—comprising power delivery, chillers, and battery energy storage systems—with MG4AI’s AI-ready compute architecture, we are redefining how power directly interfaces with compute. Our modular data center systems can deliver up to 1 MW per rack and are future-proofed to accommodate the next four generations of NVIDIA GPUs, setting a new standard for AI infrastructure. In this rapidly evolving AI landscape, speed-to-power, speed-to-market, and speed-to-revenue provide a decisive competitive advantage.”
Transforming Data Centers for the AI Era
The integration of Capstone’s microturbine technology into AI-focused data centers marks a significant shift in how energy efficiency and computational performance are approached. Traditional AC-powered data centers often rely on multiple energy conversion steps, which introduce inefficiencies and increase operational costs. By providing direct 800 VDC power, the Capstone-MG4AI solution reduces conversion losses, lowers thermal load requirements, and improves overall system reliability.
Moreover, the partnership supports sustainability goals by combining natural gas microturbines, which have a lower carbon footprint than traditional power generation methods, with energy-efficient liquid-cooled data center designs. This approach addresses one of the biggest challenges facing modern AI infrastructure: balancing escalating power demands with environmental responsibility.
Future Outlook and Industry Implications
The 800 VDC microturbine package signals a broader shift in the industry toward modular, high-efficiency, and rapidly deployable AI infrastructure. As AI workloads continue to grow in size and complexity, data centers must evolve to meet demands without sacrificing efficiency, reliability, or sustainability. Capstone and MG4AI’s solution exemplifies this evolution, providing a scalable blueprint for next-generation AI deployments worldwide.
By combining modular design, high-voltage DC power, and integrated cooling and compute systems, the companies are positioning themselves as leaders in a new era of AI infrastructure development. This approach not only facilitates rapid deployment and expansion but also supports sovereign AI initiatives and enterprise computing strategies that require independence from traditional grid constraints.
“This partnership is about more than just delivering power—it is about enabling a new generation of AI innovation,” added Canino. “With AI workloads growing exponentially, energy solutions must keep pace. Capstone and MG4AI are providing the tools that data center operators need to meet the AI demands of today and tomorrow, efficiently and sustainably.”
As the AI Factory concept becomes central to data center design and operations, the Capstone 800 VDC microturbine solution will likely play a pivotal role in powering the next wave of AI breakthroughs. From edge deployments to giga-scale AI campuses, this collaboration represents a strategic leap forward in marrying energy efficiency, scalability, and computational performance.
