Coal Plus Hydrogen: Chinese Engineers Have Learned to Burn 50 Percent Pure Green Gas at Power Plants. What Does This Mean for the Climate?
50 percent hydrogen by calorific value, up to 50 percent carbon emission reduction, a domestically developed low‑NOx burner and a comprehensive safety system

China has achieved a technological breakthrough in clean energy production, enabling the use of a 50 percent share of green hydrogen in coal‑fired power plants, reaching 100 percent hydrogen combustion, state‑owned energy company CHN Energy said on Sunday.
The breakthrough comes as China, the world’s largest electricity consumer, seeks viable paths to meet its “dual carbon” goals — peaking carbon emissions by 2030 and achieving carbon neutrality by 2060.
The system operates on a domestically developed low‑NOx hydrogen‑coal co‑firing burner. It is equipped with a comprehensive safety system that monitors every stage — from hydrogen transport to combustion in the furnace.
The technology ensures thorough mixing and burning of hydrogen and pulverised coal inside the boiler, achieving a 50 percent hydrogen co‑firing ratio by calorific value at this pilot facility.
Widespread adoption could cut coal consumption and carbon emissions by up to 50 percent, while also providing effective control of nitrogen oxide emissions.
China currently operates the world’s largest fleet of coal‑fired power plants. Finding ways to reduce their carbon footprint is considered vital for maintaining grid stability while ramping up renewable energy use.
This breakthrough confirms a highly promising technical pathway for substantially cutting carbon emissions from future coal‑fired power plants and is of great significance for China’s green transition in coal‑based electricity generation.
“Green” hydrogen is produced from renewable energy sources (solar, wind, water) through electrolysis. Co‑firing hydrogen with coal allows carbon dioxide emissions to be reduced without completely abandoning existing coal infrastructure.
Coal power plants are major polluters. But if they cannot be shut down overnight, they can be made cleaner. China has found a way: add hydrogen to the furnace. Fifty percent hydrogen by calorific value is not an experiment. It is already a working technology. Less coal — fewer emissions. The same power, but twice as clean. A comprehensive safety system, a low‑NOx burner, monitoring at every stage. The question is not whether coal power can be made greener. It already can. The question is how quickly the world will adopt such hybrid technologies. While others argue, China is already building. And cutting emissions. Literally before our eyes.
