Wärtsilä operates world's first large-scale 100% hydrogen combustion engine, feeding power to Spain's grid

Summary

Finnish company Wärtsilä has successfully operated the world's first large-scale 100% hydrogen combustion engine in Bermeo, Spain. The 13,000-horsepower piston engine, roughly the size of a bus, was fed pure hydrogen and generated electricity that was fed into Spain's national grid. This development contrasts with Toyota's long-standing approach of using hydrogen exclusively in fuel cells rather than direct combustion. The achievement represents a significant milestone in hydrogen power technology, demonstrating an alternative pathway for using hydrogen as a clean energy source for large-scale power generation.
