Switzerland, Zurich: Hitachi, Ltd. and Hitachi Energy have announced support for NVIDIA’s 800-volt direct-current (VDC) power architecture, developing a system designed to improve energy efficiency and reduce power losses in AI data centres. The collaboration focuses on creating a more streamlined and sustainable way to supply power to large-scale computing facilities.

Rising AI workloads are driving data centres beyond the capacity of conventional power architectures. Hitachi Energy’s grid-to-rack design supports the 800 VDC rack concept, simplifying the flow of electricity from the grid to the server. This approach aims to lower energy conversion losses, reduce cooling needs, and make power distribution more efficient for high-performance computing environments.

Jun Taniguchi, Senior Vice President and Executive Officer at Hitachi, Ltd., said the cooperation reflects Hitachi’s long-standing expertise in power systems and digital technologies and its intention to contribute to the development of energy-efficient data infrastructure.

Hitachi estimates that up to 125 GW of AI data centre capacity could be added globally by 2030, which is comparable to Spain’s total installed generation capacity. To meet this growth, Hitachi Energy is investing $9 B worldwide to expand manufacturing, research, and partnerships, including $1 B in the United States to advance grid technology and production capacity.

These initiatives aim to align the expansion of digital infrastructure with sustainable power systems and grid reliability.
