en.Wedoany.com Reported - Finnish energy technology company Wärtsilä has launched grid-connected testing of a 100% hydrogen engine at its laboratory in Bermeo, northern Spain. The Spanish hydrogen engine test uses the Wärtsilä 31H2 engine, running on 100% hydrogen fuel, and has supplied power to the Spanish national grid during the testing period.

This Spanish hydrogen engine test is part of Wärtsilä's validation work for its new hydrogen-fueled engine, focusing on verifying the engine's operational capability to generate electricity using 100% hydrogen under real grid conditions. Unlike equipment that only supports hydrogen blending, this test operates on pure hydrogen fuel, targeting future flexible regulation needs as the share of wind and solar power increases.

Wärtsilä stated that engine-based power generation can serve as a dispatchable power source to support grid balancing amid fluctuations in renewable energy. The Spanish hydrogen engine test will continue to validate operational stability, control strategies, and grid adaptability. As the 100% hydrogen grid-connected test progresses, hydrogen power generation equipment will gain more engineering data for applications in industrial parks, data centers, and backup regulation in power systems.
