China Commissions World's Largest 30MW Pure Hydrogen Super-Turbine, Jupiter I, in Inner Mongolia

Groundbreaking Hydrogen Turbine Begins Operation

China has marked a significant milestone in clean energy technology with the successful commissioning of Jupiter I, the world's first 30-megawatt (MW) pure hydrogen gas super-turbine. The turbine, installed in the Etuoke Banner (Otog Banner), Ordos City, Inner Mongolia Autonomous Region, began stable operation and achieved 100 percent hydrogen power generation in late December 2025. This development positions China at the forefront of hydrogen energy innovation, offering a robust solution for renewable energy storage and utilization.

Engineering Marvel and Environmental Impact

Developed by Mingyang Hydrogen, a subsidiary of Mingyang Smart Energy, in collaboration with scientific research teams, Jupiter I is heralded as the largest single-unit pure hydrogen generator globally. The turbine is designed to address the intermittency of renewable energy sources like wind and solar power. It operates on a 'power-to-hydrogen-back-to-power' cycle, converting surplus green electricity into hydrogen for storage, which can then be reconverted into electricity during peak demand periods.

In combined-cycle operation, Jupiter I can generate approximately 48,000 kilowatt-hours (kWh) per hour, sufficient to meet the daily electricity needs of about 5,500 households. This innovative system is projected to reduce carbon emissions by more than 200,000 metric tons per year compared to a thermal power unit of equivalent capacity, contributing significantly to China's carbon neutrality goals.

Technological Advancements and Future Prospects

The successful development of Jupiter I involved overcoming complex technical challenges associated with hydrogen combustion, such as flashback, oscillation, and high oxynitride emissions. The engineering team achieved this through an innovative combustion chamber design, including the use of 3D printing for integrated combustion chamber nozzles.

The Jupiter I project is an integral part of a larger hydrogen energy storage demonstration initiative in Inner Mongolia. This comprehensive project integrates:

• A 500 MW wind power project
• Hydrogen production facilities with a capacity of 48,000 Nm³/h via water electrolysis
• Twelve spherical tanks, each with a capacity of 1,875 m³, for hydrogen storage
• A supporting green ammonia plant

This integrated approach aims to stabilize the power grid, absorb surplus renewable power, and provide a scalable solution for building a new energy system with renewables as the mainstay. The successful operation of Jupiter I marks a critical step in China's broader energy transition strategy, demonstrating the feasibility of utility-scale pure hydrogen power generation.
