Hitachi Energy, in collaboration with Stena Line, PowerCell Group, Linde Gas, and the Port of Gothenburg, has successfully demonstrated HyFlex™, a groundbreaking hydrogen-powered energy supply system. The test, conducted over two weeks, involved powering one of Stena Line’s ferry vessels using green hydrogen fuel while connected to the existing shore power system.
Zero-Emission, Scalable, and Portable
HyFlex is a zero-emission, plug-and-play solution that generates electricity, heat, and water. Its scalable and portable design allows rapid deployment, making it ideal for locations with limited grid access or remote energy needs. A 1 MVA HyFlex unit can replace up to 1,600 tons of diesel fuel annually, reducing CO₂ emissions by approximately 5,800 tons.
Supporting Grid Operations
As part of the demonstration, HyFlex was connected directly to the local power grid, proving its capability to support grid operations and supply clean energy in a port environment. The real-time data collected will further refine the system and strengthen the case for hydrogen as a viable energy carrier in industrial applications.
Alignment with Upcoming EU Regulations
The demonstration is especially timely, considering upcoming EU maritime regulations set for 2030. These rules will require ships over 5,000 gross tons to use onshore power supply (OPS) or zero-emission technology in ports, making solutions like HyFlex increasingly essential.
Expanding Use Cases for HyFlex
This success builds on previous efforts by Hitachi Energy, including the decarbonization of a construction site in the Port of Gothenburg. In that project, an islanded hydrogen-powered generator provided clean power to an electric excavator—marking the first real-world use of HyFlex. The system’s versatility demonstrates its potential for broad adoption across marine, construction, and other off-grid sectors.
HyFlex showcases how hydrogen fuel cell technology can play a pivotal role in the transition to clean energy, particularly in challenging environments where traditional grid solutions fall short.
