Inner Mongolia is building a super-large integrated energy project that may change the global energy landscape, with the core of which is the world's first large-scale gas turbine completely fueled by pure hydrogen. This 30 MW technological breakthrough marks a critical node for hydrogen from laboratory to industrial-scale applications, while providing a systematic solution to the intermittent problem of renewable energy. The project not only represents China's major innovations in the field of clean energy technology, but is also likely to provide new technological paths for global energy transformation.
Unlike the previous technical routes for mixing hydrogen and natural gas, this turbine will achieve 100% hydrogen combustion power generation. The difficulty and significance of this technological breakthrough cannot be underestimated. Pure hydrogen combustion involves collaborative innovation in multiple technical fields such as complex materials science, combustion control and system safety, and its success will lay a solid foundation for the large-scale commercial application of hydrogen energy.

This project in Inner Mongolia adopts an unprecedented closed-loop energy system design, integrating 500 MW of wind power, 5 MW of solar power, large-scale electrolytic hydrogen production, hydrogen storage and hydrogen gas turbine power generation into one organic whole. The electrolytic device equipped with the system can produce 48,000 cubic meters of hydrogen per hour and is stored on a large scale through 12 spherical storage tanks, forming a complete "electric-hydrogen-electric" energy conversion cycle.
The design concept of this system solves the core problems in the development of renewable energy: intermittentity and storage issues. When wind and solar power are sufficient, excess power is used to generate hydrogen by electrolyzing water; when renewable energy generation is insufficient, the stored hydrogen can be quickly converted into electricity through the gas turbine to achieve dynamic balance of the power grid. This technological pathway provides a viable solution for large-scale renewable energy grid connection.
More importantly, the project also integrates the chlorammonia production function, with an annual production capacity of 150,000 tons. Ethylammonia is not only an important industrial raw material and cleaning fertilizer, but can also be transported as a carrier of hydrogen for long distances. It is also a potential cleaning fuel for sea and heavy transportation. This diversified product structure greatly improves the economic feasibility and market adaptability of the project.Engineering Challenges Behind Technological Breakthrough
The technical implementation of pure hydrogen gas turbines faces a series of unprecedented engineering challenges. The combustion characteristics of hydrogen are significantly different from those of traditional fossil fuels. Its characteristics such as fast combustion speed, high flame temperature, and easy tempering have put forward extremely high requirements for the design of the turbine. Engineers must redesign the combustion chamber, blade materials and cooling systems to meet the special requirements of hydrogen combustion.
The hydrogen embrittlement problem is another key technical problem. Hydrogen molecules are extremely small and easily penetrate into metal materials, causing material embrittlement, which poses a threat to the long-term reliability of the turbine. The project team needs to develop special hydrogen-resistant materials and protection technologies to ensure the safe operation of the equipment in a long-term hydrogen environment.
In addition, the safe processing and storage of hydrogen are also the focus of system design. The explosion limit range of hydrogen gas is wide, and the requirements for leakage detection and emergency response are extremely high. The 12 spherical tank designs adopted by the project need to meet strict safety standards, including multiple safety measures such as leakage prevention, explosion prevention and fire prevention.
Strategic significance of global hydrogen energy industry development
The launch of this project is a critical period of rapid development of the global hydrogen energy industry. According to the latest report from the International Energy Agency, global hydrogen investment has increased tenfold in the past five years, with several developed countries developing ambitious hydrogen development strategies. The EU plans to build 40 GW of electrolytic hydrogen production capacity by 2030, and Japan and South Korea are also actively deploying the entire hydrogen energy industry chain.
China has shown obvious technological and scale advantages in this round of hydrogen energy competition. Data shows that in the first five months of 2025, China added 198 GW of solar installed capacity and 46 GW of wind installed capacity, which is almost equivalent to the total installed capacity of Indonesia or Türkiye. This super-large-scale renewable energy construction provides sufficient green electricity resources for the development of the hydrogen energy industry.
Inner Mongolia, as an important energy base in China, has rich wind and solar resources, providing ideal geographical conditions for large-scale hydrogen production projects. The region is building a national hydrogen energy industry center, and this pure hydrogen gas turbine project will become the core demonstration project.
Economic feasibility and market prospects
The commercial promotion of hydrogen energy technology has always faced costly challenges, especially the energy loss problem during the "electric-hydrogen-electric" conversion process. Currently, the efficiency of electrolytic hydrogen production is about 70-80%, and the power generation efficiency of hydrogen gas turbines is about 40-50%, and the overall efficiency of the entire cycle is relatively low. However, with the continued decline in renewable energy costs and the continuous maturity of hydrogen energy technologies, the economy of this model is improving rapidly.
The latest research from Bloomberg New Energy Finance shows that the production cost of green hydrogen is expected to drop by more than 50% by 2030, giving it a competitive advantage with traditional fuels in multiple application scenarios. Especially in the fields of long-term energy storage, industrial raw materials and long-distance transportation, hydrogen energy has irreplaceable advantages.
The chloramide production function of this project further enhances its economic feasibility. As the world's second largest chemical product, ammonia has an annual output of more than 180 million tons and stable market demand. Traditional ammonia production processes rely on fossil fuels and emit huge carbon emissions. Large-scale production of chlorammonia can not only reduce the carbon footprint of the chemical industry, but also create considerable economic benefits.
Demonstration effect on global energy transition
The success of this project will provide important technical verification and business model reference for the development of the global hydrogen energy industry. At present, countries around the world are exploring hydrogen energy development paths that are suitable for their national conditions, but there are few successful cases of large-scale industrial applications. If this project in China is successful, it will prove the feasibility and reliability of pure hydrogen gas turbine technology.
From the perspective of technological diffusion, this integrated energy system design is highly replicable. Other countries and regions with rich renewable energy resources can learn from this model and make adaptive adjustments based on local conditions. This will accelerate the popularization and application of hydrogen energy technology worldwide.
This project is also in line with China's "dual carbon" strategic goal, namely, achieving carbon peak by 2030 and carbon neutrality by 2060. Hydrogen energy, as an important link connecting power systems, industrial systems and transportation systems, will play a key role in China's energy transformation.
Looking forward, similar large-scale hydrogen energy comprehensive projects may be rapidly promoted worldwide as hydrogen energy technology continues to mature and cost continues to decline. This will not only promote the advancement of clean energy technology, but will also provide important technical support for achieving the global carbon neutrality goal. China's first breakthrough in this field will undoubtedly win an important strategic advantage for it in the future competition for clean energy.
