Hitachi Energy has successfully demonstrated HyFlex, an innovative energy supply system based on zero-emission hydrogen-powered fuel cell technology, in collaboration with industry partners at the Port of Gothenburg in Sweden. HyFlex's two-week test showcased its ability to generate clean electricity using green hydrogen as fuel for ships at berth, offering a sustainable alternative to diesel generators. This cutting-edge system is flexible, scalable, and designed for easy deployment, addressing challenges like remote power needs. The initiative not only reduces diesel fuel consumption and CO2 emissions but also supports the new EU regulations mandating zero-emission technology in ports by 2030. The collaboration between Hitachi Energy, Stena Line, Power Cell Group, Linde Gas, and the Port of Gothenburg accelerates sustainable solutions for port operations and demonstrates the potential of hydrogen as a clean energy carrier. With the successful demonstration of HyFlex, Hitachi Energy continues to lead in innovative, sustainable energy solutions, driving the energy transition in various sectors.
