On June 7, 2026, in a laboratory of the National Energy Group in Beijing, the flames on the monitoring screen showed an unprecedented pure blue color. As the technicians slowly pushed up the hydrogen flow valve, the fuel structure inside the boiler quietly changed - China's independently developed hydrogen coal co firing technology officially announced the breakthrough of the dual barrier of 50% green hydrogen high proportion co firing and 100% pure hydrogen combustion at this moment. This leaping flame is rewriting the carbon reduction script for the world's largest coal-fired power system in the future.

More than half of the blending ratio

This technology relies on a completely independently designed hydrogen coal mixed combustion low nitrogen burner to successfully construct a full process protection system from hydrogen transportation to furnace combustion.

Experimental data shows that under the condition of 50% heat ratio mixed with hydrogen, hydrogen and coal powder achieve full fusion combustion in the furnace, with coal saving and carbon reduction reaching 50% synchronously, and effectively controlling the generation of nitrogen oxides, verifying the feasibility of large-scale application.

Million unit adaptation

China has the world's largest coal-fired power plant, and its green transformation is crucial to the success or failure of its dual carbon goals. This technological breakthrough provides a practical and feasible low-carbon transformation plan for existing coal-fired units, enabling old power plants to achieve significant carbon reduction through the connection of green hydrogen pipelines without the need for complete demolition and reconstruction, and meet the demand for new energy consumption.

The zero carbon pathway is beginning to emerge

The technological ladder has been paved from hydrogen blending combustion to 100% pure hydrogen combustion. This is not only a technological path for the integrated development of coal-fired power and green hydrogen industries, but also a safeguard for China's energy security. In the future, as the cost of green hydrogen decreases, this technology will promote a smooth transition of thermal power from base load power sources to regulated power sources, reshaping the underlying logic of the power system.Editor/Gao Xue
