Wärtsilä’s fully hydrogen-ready engine power plant – which is now in the certification and design phase – is expected to be available for orders in 2025 with delivery a year later.
The concept, based on the Wärtsilä 31 engine platform, has been initially certified by TÜV SÜD – whose H2-Readiness certification consists of three stages with three corresponding certificates.
The platform synchronises with the grid within 30 seconds from start command, ensures energy security through fuel flexibility and offers ‘unparalleled’ load following capabilities and high part load efficiency.
It has completed more than 1 million running hours, with over 1,000 megawatts (MW) installed capacity globally. The new engine power plant is a significant step beyond existing technology, which can run on natural gas and 25% volume hydrogen blends.
