Hitachi Energy has launched HyFlex® Compact, a portable hybrid generator and flexible power hub designed to deliver zero-emission electricity for temporary and off-grid applications. Combining hydrogen fuel cells with high-performance batteries, the system can integrate additional energy sources through configurable AC and DC input modules, providing stable alternating current power as a clean alternative to diesel generators.
As demand for reliable, low-emission power grows across construction sites, infrastructure projects, electric vehicle charging, mining operations and other remote or critical environments, HyFlex Compact offers a single-enclosure solution that supports both standalone and grid-connected operation. The unit houses fuel cells, batteries, power electronics, cooling equipment and auxiliaries, all managed by an optimized control system. When operating on hydrogen, the fuel cells convert the gas into electricity, heat and water without producing harmful emissions.
Optional input modules enable the system to function as a mobile microgrid, tying in solar arrays, shore power or other generation assets. This flexibility not only enhances operational efficiency but also reduces hydrogen consumption when supplementary 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.”
Building on earlier HyFlex pilot projects—including zero-emission construction sites in the Netherlands, hydrogen-powered generators for ships at berth and decarbonization trials in Sweden—the launch underscores Hitachi Energy’s commitment to flexible, low-emission solutions. Recent investments in power electronics capabilities, such as the new Grid & Power Quality Solutions and Service Test Center in Västerås, Sweden, and a Power Electronics Center of Competence in the United States, further bolster the company’s ability to support secure, sustainable and resilient electricity systems worldwide.
