Hitachi Energy Expands Zero-Emission Power Portfolio With HyFlex Compact

• Hybrid generator and flexible power hub that combines hydrogen fuel cells with high-performance batteries to deliver an emission-free alternative to diesel generators
• Provides stable AC power whenever and wherever it’s needed, with configurable input modules to connect multiple energy assets

Hitachi Energy, a global leader in electrification, has introduced HyFlex Compact – a hybrid generator and flexible power hub that provides zero-emission electricity for temporary and off-grid applications such as construction projects and other infrastructure. 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.

Addressing these requirements calls for power solutions that go beyond single technologies, supported by robust system expertise and integration capabilities. 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 optimized 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.

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.” - Marco Berardi Head of Grid & Power Quality Solutions and Service Hitachi Energy

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 marks an evolutionary step, building 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.

Hitachi Energy continues to bring flexible, low-emission solutions to market, underpinned by its expertise in power electronics and system integration. Recent investments in power electronics capabilities, including the inauguration of the Grid & Power Quality Solutions and Service Test Center in Västerås, Sweden, and the announcement of a new Power Electronics Center of Competence in the United States, underscore the company’s focus on strengthening the technologies needed to support secure, affordable, sustainable and resilient electricity systems.
