Wärtsilä launches world’s first large-scale hydrogen-ready power plant

Groundbreaking technology to enable net-zero power systems, supporting renewable energy with hydrogen-based fuels.

Technology group Wärtsilä has today launched the world’s first large-scale, 100 percent hydrogen-ready engine power plant, designed to enable the net-zero power systems of the future.

The IEA World Energy Outlook 2023 shows that hydrogen is an essential component of our future power systems. According to the report, the pathway to reach net zero emissions by 2050 requires 17 Mt of hydrogen to be consumed in power generation by 2030, increasing to 51 Mt by 2050.

The deployment of renewables worldwide is set to double by the end of this decade, creating the right conditions for excess clean electricity to be used for producing hydrogen-based, carbon-neutral fuels, and for enabling 100 percent renewable power systems.

Scaling up renewables alone, however, is not enough to reach global net zero targets. Flexible power generation solutions, like engine power plants, are needed to balance fluctuating renewable energy sources. It is crucial that these solutions are future-proof and ready to run on sustainable fuels to fully decarbonise the energy sector.

Wärtsilä is addressing this need through its new hydrogen-ready engine power plant, which can be converted to run on 100 percent hydrogen. This new engine power plant is a significant advancement over existing technology, which can only run on natural gas and 25 vol% hydrogen blends.

Anders Lindberg, President, Wärtsilä Energy, said: “We will not meet global climate goals or fully decarbonise  our power systems without flexible, zero-carbon power generation, which can quickly ramp up and down to  support intermittent wind and solar.  

“We must be realistic that natural gas will play a part in our power systems for years to come. Our fuel flexible  engines can use natural gas today to provide flexibility and balancing, enabling renewable power to thrive.  They can then be converted to run on hydrogen when it becomes readily available: future-proofing the  journey to net zero. 

“This is a major milestone for us as a company, and the energy transition more generally, as our hydrogen ready engines will enable the 100 percent renewable power systems of tomorrow.” 

The Wärtsilä 31 engine platform, on which the hydrogen-ready power plant is based, is the most efficient in the world. It synchronizes with the grid within 30 seconds of a 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 MW of installed capacity globally.

Wärtsilä’s 100 percent hydrogen-ready engine power plant concept, based on the Wärtsilä 31 engine platform, has been certified by TÜV SÜD, demonstrating a commitment to quality and safety. TÜV SÜD’s H2-Readiness certification consists of three stages with three corresponding certificates.

Wärtsilä has now achieved the first stage with a Concept Certificate for the conceptual design of its engine power plant. The 100 percent  hydrogen-ready engine is expected to be available for orders in 2025 and available for delivery from 2026.
