Addressing the just transition ideology of Africa, technology group Wärtsilä has introduced a purely hydrogen-ready engine power plant
Guided by the IEA World Energy Outlook 2023 that predicts hydrogen consumption to reach 51 mt by 2050, Wärtsilä's launch establishes the importance of an energy mix. Sustainable fuels like hydrogen and natural gas are significant to balance the fluctuating renewable energy sources.
Wartsila has been working towards ensuring energy mix since the last few years, when it announced the conversion of the heavy fuel-operated Bel-Air power plant in Dakar to LNG.
The new engine power plant can run on natural gas and 25 vol% hydrogen blends.
Addressing energy security
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% renewable power systems of tomorrow.”
The Wärtsilä 31 engine platform that is the driving force behind the hydrogen-ready power plant is designed for instant operation, synchronising with the grid within 30 seconds from start command.
Having completed more than 1 million running hours, with over 1,000 MW installed capacity globally, the platform offers unparalleled load following capabilities and high part load efficiency. Its fuel flexibility is hence capable of meeting present challenges of energy security.
With hydrogen catching up at a rapid pace in Africa, the Wärtsilä 31 engine is all set to hit the markets next year, followed by delivery services from 2026.
