     Currently, hydrogen is commonly used as rocket fuel in the aerospace field. Internationally, significant progress has been made in research on gas turbines that co-fire hydrogen and natural gas, and even pure hydrogen gas turbines. However, hydrogen fuel blends with high hydrogen ratios face several technical challenges, including flashback, combustion pressure fluctuations, and nitrogen oxides. Overcoming these technical hurdles will still take time. As a transitional step toward hydrogen-rich or pure hydrogen gas turbines, the advantages of natural gas-hydrogen fuel blends in power generation are becoming increasingly evident. By adding hydrogen to natural gas, the combustion rate of natural gas can be increased, and the stable lean-burn limit of natural gas can be extended. This fully leverages the benefits of both hydrogen and natural gas fuels, not only significantly reducing emissions of pollutants such as carbon dioxide and nitrogen oxides, but also providing technical reserves for large-scale hydrogen energy utilization.

      Currently, GE Power has provided customers with mature gas power solutions. And forward-thinking GE engineering experts have long equipped GE gas turbines with comprehensive future-ready capabilities, initiating practices in the application of hydrogen in gas turbines. Jeff Goldmeer, of GE Power's Gas Systems, who previously worked at NASA and is familiar with hydrogen applications in the aerospace field, stated: "Our customers often ask how they can utilize hydrogen energy in power generation to achieve a more environmentally friendly way of generating electricity. I proudly tell them that many GE devices already have the capability to burn hydrogen, and this vision is gradually being realized!" GE has operational experience using hydrogen as a blended fuel in over 70 gas turbine units operating in the United States, Asia, and Europe, accumulating more than four million operating hours.
