The configurable system combines hydrogen fuel cells with high-performance batteries and can integrate additional power sources, delivering stable AC power as a clean alternative to diesel generation.
As electricity demand rises, companies across industry and infrastructure are electrifying operations and cutting emissions, often in locations where grid connections are limited or unavailable. This is increasing demand for flexible power solutions that can perform reliably across a wide range of operating conditions, from remote sites to grid-connected environments.
Designed for standalone or grid-connected operation, Hitachi Energy’s HyFlex Compact combines hydrogen fuel cells, batteries, power electronics, cooling, and auxiliaries in a single, portable enclosure, all managed by an optimised control system. The system converts hydrogen into clean electricity using fuel cells, producing power, heat, and water with no harmful emissions.
With optional AC and DC input modules, Hyflex Compact can operate as a mobile microgrid, connecting multiple energy assets, providing stable AC power whenever and wherever it is needed. This enables more efficient operation and reduces reliance on hydrogen when additional power sources are available.
“The energy system is being asked to deliver more electricity, with lower emissions and higher resilience, often in places where the grid was never designed for today’s demands” said Marco Berardi, Head of Grid & Power Quality Solutions and Service at Hitachi Energy. “HyFlex Compact brings together different technologies through system integration expertise to support a secure electricity supply as energy systems evolve, while helping companies move toward lower-emission power.”
HyFlex Compact is suitable for applications across a wide range of operating environments, from construction sites and temporary infrastructure such as events and festivals to electric vehicle charging, mining operations, remote industrial sites, critical infrastructure, and hard-to-abate operating environments.
The introduction of the flexible power hub builds on Hitachi Energy’s earlier HyFlex developments. Initial pilots explored hydrogen-to-power applications and provided valuable insight into integrating fuel cells, power electronics, and control systems in real‑world operating environments.
