en.Wedoany.com Reported - Finnish technology group Wärtsilä has, for the first time, operated a large engine running on 100% hydrogen and fed electricity directly into the Spanish national grid in Bermeo, northern Spain. The company states that this is the world's first test of large internal combustion engine technology under full hydrogen operation and real grid conditions.
The 31H2 engine used in this test is developed based on the Wärtsilä 31 platform, which the company claims has been deployed in numerous power plants globally and is one of the most efficient multi-fuel engine platforms of its kind currently available. The new variant is specifically designed for pure hydrogen operation and is currently being validated in a real grid environment.
Rasmus Teir, Director of Technology Strategy and Decarbonisation at Wärtsilä, stated that as countries rapidly expand wind and solar power capacity, one of the biggest challenges in the energy transition is sustainably maintaining a reliable power supply during periods of low renewable generation or peak demand. He described this test as "a trial for the future of renewable energy."
As installed wind and solar capacity continues to grow, the demand for fast-ramping power generation capacity is increasing to balance supply and demand when variable power sources are connected. Hydrogen engines are being positioned as a potential solution for flexible backup and peaking power in the electricity system. Wärtsilä also believes that this technology could be used in the future for energy-intensive industries such as industrial applications, data centers, and distributed energy systems.
This demonstration comes at a time when hydrogen infrastructure development and the availability of green hydrogen are widely regarded as key factors for widespread market adoption. The core of scaling this technology lies in whether hydrogen can quickly establish itself as a tradable and readily available energy carrier, and whether this process can advance in tandem with the expansion of renewable energy generation capacity. Rasmus Teir stated that the technology is ready; what is needed now is to create the appropriate regulatory and investment environment, as well as the infrastructure required to accelerate the growth of renewable energy and sustainable fuels like hydrogen, to drive large-scale development.
