Hitachi Energy has successfully showcased its innovative HyFlex™ energy supply system, a hydrogen-powered fuel cell technology, in partnership with Stena Line, Power Cell Group, Linde Gas, and the Port of Gothenburg. In a two-week trial, HyFlex generated electricity using green hydrogen as fuel, seamlessly integrated with the existing shore power system of one of Stena Line’s ferry vessels.
HyFlex is a state-of-the-art, zero-emission system that produces electricity, heat, and water. Its flexible, scalable, and portable design allows for easy deployment and immediate use, making it a valuable solution for areas with limited grid capacity or remote power needs. Compared to traditional diesel generators, a 1 MVA (megavolt-ampere) HyFlex unit can reduce diesel fuel consumption by up to 1,600 tons annually, which translates to a saving of 5,800 tons of CO2.
The demonstration at the Port of Gothenburg marked a significant advancement, as HyFlex was connected directly to the local power grid, highlighting its ability to support grid stability. The data collected during the test will be crucial for refining the solution, reinforcing hydrogen’s potential as a clean energy source and proving the technical feasibility of fuel cell technology in port settings.
This initiative aligns with the European Union’s upcoming 2030 regulations, which mandate ships over 5,000 gross tonnages to utilize onshore power supply (OPS) or zero-emission technology while docked in ports.
Anders Peterson, Group Head of Port Development & Engineering at Stena Line, emphasized the importance of testing new technologies aimed at reducing emissions within the maritime industry. “This project demonstrates that there are alternative solutions for ports that lack adequate electricity infrastructure.”
Tobias Hansson, Country Managing Director at Hitachi Energy in Sweden, expressed excitement over the collaboration. “We are delighted with the results and the opportunity to work with key industry players to explore new applications for HyFlex, accelerating the energy transition across various sectors, from construction sites to ship terminals.”
The HyFlex demonstration builds on Hitachi Energy’s previous efforts to decarbonize operations, such as their project to power a construction site in the Port of Gothenburg with a hydrogen-powered generator. This latest achievement further underscores the scalability and versatility of HyFlex in supporting sustainable energy solutions across a wide range of industries.
