Wärtsilä has launched the world’s first large-scale 100% hydrogen-ready engine power plant, a significant advancement towards enabling net-zero power systems in the future. The IEA's World Energy Outlook 2023 underscores the importance of hydrogen in future power systems, with projections indicating a substantial increase in hydrogen consumption for power generation by 2050 to achieve net-zero emissions. The growth of renewable deployment globally sets the stage for using excess clean electricity in producing hydrogen-based, carbon-neutral fuels, thus facilitating the transition to 100% renewable power systems. Wärtsilä's hydrogen-ready engine power plant, based on the efficient Wärtsilä 31 engine platform, is designed to operate on 100% hydrogen, offering fuel flexibility to balance fluctuating renewable energy sources. This innovation ensures the energy sector's decarbonization by providing a path to switch from natural gas to hydrogen when readily available, thus supporting the journey to net zero emissions. The Wärtsilä 31 engine platform boasts high efficiency, rapid grid synchronization, energy security through fuel flexibility, and exceptional load-following capabilities and part load efficiency. The hydrogen-ready engine plant concept has received certification from TÜV SÜD, signifying a commitment to quality and safety. Expected to be available for orders in 2025 and delivery in 2026, this innovation represents a significant milestone towards enabling the 100% renewable power systems of tomorrow.
