Capstone Green Energy Holdings, Inc. and its subsidiaries, a leading provider of clean, low-emission microturbine energy systems, have joined forces with Microgrids 4 AI, Inc. (MG4AI), a developer of modular, AI-ready data center solutions, to unveil an innovative 800-volt direct-current (VDC) microturbine plus compute engineered equipment package. This cutting-edge solution is designed to power the next generation of AI infrastructure efficiently and sustainably.
The announcement, made during Data Center World Asia on October 9, places Capstone and MG4AI at the forefront of a major industry shift toward 800 VDC architectures. NVIDIA and other leading data center infrastructure players have been advocating this transition to support megawatt-scale AI workloads, and the new system aligns perfectly with these evolving requirements.

Capstone’s 800 VDC natural gas microturbine extends its existing inverter-based power electronics technology. By directly interfacing with upcoming Kyber and Rubin Ultra platforms, the system eliminates multiple AC/DC conversion stages, reduces copper usage by up to 45%, and enhances overall power efficiency by approximately 5% compared to conventional 54V systems.
“The evolving AI Factory design fundamentally challenges the energy delivery requirements and norms,” said Vince Canino, President & CEO of Capstone Green Energy. “Today’s AI racks already exceed 200 kW and are rapidly approaching 1 MW. Our 800 VDC microturbine is designed for this new reality, whilst building clean, reliable, redundant and direct high-voltage DC power to the next generation of AI Factories. Simply put, exciting challenges in powering the digital age.”
The collaboration between Capstone and MG4AI extends beyond power generation. By integrating the 800 VDC microturbine with MG4AI’s modular, liquid-cooled data center kits, they are creating turnkey, grid-independent ‘AI Power Blocks.’ These all-in-one units deliver power, liquid cooling, and compute as a unified, rapidly deployable system. They can scale from edge deployments under 20 MW to AI giga-campuses exceeding 1 GW, supporting sovereign, enterprise, and commercial AI environments.

“The AI Factory demands infrastructure that is smarter, better and faster,” said Ken Kajikawa, CEO of Microgrids 4 AI. “By aligning Capstone’s 800 VDC microturbine along with its Engineered Equipment Package (EEP) of power, chillers and BESS with MG4AI’s AI-ready compute architecture, we are now redefining how power becomes a true handshake with compute. Our modular data center (MDC) systems deliver up to 1MW per rack which are future proofed for NVIDIA’s next four GPU generations the new foundation of the next AI era. Time to power, time to market, and time to revenue are what creates the true competitive advantage in this fast-moving AI Factory race.”
By combining advanced microturbine technology with scalable AI-ready infrastructure, Capstone and MG4AI are not only addressing the energy demands of modern AI but also paving the way for more sustainable, efficient, and powerful data centers worldwide.
