UK-based engineering firm Ricardo has made a significant breakthrough in hydrogen fuel cell technology by achieving a remarkable 393 kW electrical power output with its multi-stack hydrogen fuel cell module within a short testing period of three months. Originally developed for the maritime sector as part of the sHYpS Horizon Europe project, Ricardo's solution focuses on delivering high energy output while ensuring zero emissions. The company has also introduced containerised fuel cell solutions that stack multiple fuel cells to generate an impressive power output of 3 MW per container. By using two such containers, each with a net power output of 6 MW, Ricardo's system has the potential to power large vessels like a 50,000-tonne cruise ship with a 1,000-passenger capacity. This development signifies a significant step towards decarbonising the shipping industry. Although advancements have been made in fuel cell technology for smaller vessels, further evolution is necessary to meet the power requirements of larger ocean-going ships. Ricardo's innovation demonstrates the scalability and efficiency of hydrogen fuel cells and paves the way for a more sustainable future in the maritime sector.
