A China-based firm has achieved a groundbreaking feat by successfully igniting the world’s first 30MW-class pure hydrogen gas turbine.
Called Jupiter I, the gas turbine is jointly developed by the Mingyang Group and several other companies and scientific research teams. The turbine, which offers a key solution for renewable energy storage, converts hydrogen from storage tanks back into electricity during peak hours.
Converting excess electricity into hydrogen for storage
The major challenge with renewable energy is the substantial waste that occurs during off-peak hours. Converting excess electricity into hydrogen for storage and then back to electricity at peak times is a viable solution, according to the company. Wang Yongzhi, general manager of Mingyang Hydrogen Gas Turbine Technology, stated that using hydrogen for power generation achieves a carbon-free process known as power-to-hydrogen-back-to-power.
However, he noted that slow and inefficient conversion during peak demand periods can also lead to under-utilization, highlighting the need for high-capacity gas turbines.
Technical difficulties of hydrogen combustion
The development team successfully overcame three major technical challenges associated with hydrogen combustion: “easy backfire, strong oscillation, and high emissions.” They achieved this through iterative aerodynamic and thermal design, coupled with innovative structural design of the micro-premixed combustion chamber. This resulted in a pure hydrogen gas turbine combustion chamber design and control technology with independent intellectual property rights.
A 30MW pure hydrogen gas turbine unit can effectively solve the problem of power abandonment in wind and solar energy projects with an installed capacity of 1 million kilowatts, and improve the economy of the “Shagohuang” new energy project and the stability of power transmission in the power grid, according to STdaily.
The implementation of this pure hydrogen gas turbine demonstration project has the potential to significantly drive the diversification and clean transformation of China’s energy structure, positioning the country as a leader in hydrogen energy development and application.
