Wärtsilä, a technology leader in marine and technology solutions, has launched the world’s first large-scale engine power plant that can run entirely on hydrogen. This power plant aims to support future net-zero energy systems.
According to the IEA World Energy Outlook 2023, hydrogen is vital for future power systems. To reach net zero emissions by 2050, 17 million tonnes of hydrogen will be needed for power generation by 2030, increasing to 51 million tonnes by 2050.
Renewable energy is expected to double by the end of this decade, providing clean electricity for hydrogen production and supporting 100% renewable power systems. However, renewables alone aren’t enough to meet global net zero targets. Flexible power generation, like engine power plants, is essential to balance renewable energy sources. These plants must be able to use sustainable fuels to help decarbonize the energy sector.
Wärtsilä’s new power plant can be converted to run on 100% hydrogen, going beyond current technology that runs on natural gas and hydrogen blends. Anders Lindberg, President of Wärtsilä Energy, stated, “We need flexible, zero-carbon power generation to meet climate goals. Our engines can use natural gas now and switch to hydrogen when available, helping us reach net zero.”
The Wärtsilä 31 engine, which the new power plant is based on, is the most efficient in the world. It connects to the grid in 30 seconds, offers fuel flexibility, and has high efficiency. With over 1 million running hours and 1,000 MW installed globally, it is a proven platform.
Wärtsilä’s hydrogen-ready power plant has been certified by TÜV SÜD, achieving the first stage of certification. The 100% hydrogen-ready engine will be available for orders in 2025 and deliveries from 2026.
