AECC's 2MW-class pure hydrogen gas turbine achieves new record for continuous and stable operation duration

Recently, the first unit of the "Taihang 2" pure hydrogen gas turbine developed by AECC Gas Turbine has accumulated over 7,000 hours of operation at Shandong Taihe Science and Technology Co., Ltd., and the second unit has also accumulated over 5,000 hours of operation, marking the successful commercial operation of the 2MW-class pure hydrogen gas turbine.

As a clean and environmentally friendly energy source, hydrogen energy has attracted attention from various industries due to its zero-carbon emission characteristics. Exploring the research and development of hydrogen energy gas turbine technology to support the achievement of the "dual carbon" goals has become one of the important directions for green and low-carbon development in the gas turbine field.

Through surveys conducted by the project team of AECC Gas Turbine Zhuzhou Company, it was found that the domestic chlor-alkali industry generates a large amount of hydrogen during the hydrolysis process. Due to difficulties in storage and a lack of effective utilization pathways, this hydrogen energy is wasted. Building on the successful combustion of various hydrogen-containing gaseous fuels, including coke oven gas, in the "Taihang 2" gas turbine generator set, the project team conducted adaptive improvements and upgrades, successfully developing a domestically produced pure hydrogen gas turbine.

The "Taihang 2" pure hydrogen gas turbine has a designed power of 2MW, possesses completely independent intellectual property rights, and features a compact structure, high thermal efficiency, simple maintenance, good stability, and an annual power generation capacity of 16 million kWh, which can supplement the daily operational electricity needs of factories.

The continuous and stable operation of the "Taihang 2" pure hydrogen gas turbine unit fully demonstrates AECC Gas Turbine's research and development capabilities in breaking through key hydrogen combustion technologies by leveraging its technological advantages in aero engines. Its operational data and technical experience will provide strong support for the application optimization of domestically produced gas turbines in the field of hydrogen power generation.
