China's Mingyang Group, in collaboration with other companies and research teams, has achieved a groundbreaking milestone by igniting the world's first 30MW-class pure hydrogen gas turbine named Jupiter I. The turbine is designed to convert excess electricity into hydrogen for storage and back to electricity during peak hours, offering a solution for renewable energy storage. Wang Yongzhi, the general manager of Mingyang Hydrogen Gas Turbine Technology, highlighted the importance of using hydrogen for power generation to achieve a carbon-free process known as power-to-hydrogen-back-to-power. The development team overcame technical challenges associated with hydrogen combustion through iterative design processes, resulting in a pure hydrogen gas turbine with high capacity. The Jupiter I turbine aims to resolve the issue of electricity wastage in wind and solar energy projects, potentially transforming China's energy structure and establishing the country as a leader in hydrogen energy development. With the ability to store 500 million kWh of electricity annually through hydrogen, the turbine could facilitate large-scale, long-term energy storage in China's deserts and wastelands. This innovation is expected to have broad market prospects globally, especially in regions abundant in clean energy resources.
