China has achieved a technological breakthrough in green energy production that allows for a 50-percent green hydrogen blend in coal-fired power generation, achieving 100-percent hydrogen combustion, state-owned power giant CHN Energy said on Sunday.
The achievement comes as China, the world's largest consumer of electricity, looks for viable pathways to meet its "dual carbon" targets -- peaking carbon emissions by 2030 and achieving carbon neutrality by 2060.
Powered by a domestically developed, low-nitrogen hydrogen-coal co-firing burner, the system features end-to-end safety protections that manage every operational stage, from hydrogen transport to furnace combustion.
The technology ensures that hydrogen and pulverized coal are thoroughly mixed and burned within the boiler, achieving a 50-percent hydrogen blending ratio by heat value in this experimental facility.
Widespread adoption could reduce coal consumption and carbon emissions by up to 50 percent, as well as achieve effective control of nitrogen oxide emissions.
China currently operates the world's largest fleet of coal-fired power plants. Finding ways to lower their carbon footprint is considered vital to maintaining grid stability while scaling up renewables.
The breakthrough validates a highly promising technical path for substantial carbon reductions in future coal-fired power units and carries great significance for the green transition of China's coal-generated electricity.

For more than 1,000 years, Jingdezhen, the "porcelain capital" in east China's Jiangxi Province, has shaped how the world understands porcelain, with even discarded shards preserving a living tradition.
Weng Yanjun, president of the Jingdezhen Imperial Kiln Institute, reflected on the scale and challenge behind Jingdezhen's historic creations.
"When I look at this gigantic dragon jar, I couldn't help going back to 600 years ago, when the emperor had this order to create something bigger than ever before. The failure rate of the dragon jar is so high. It could be nine out of 10. Even making failure products like this takes courage, takes techniques and takes commitment," said Weng.
Those failed attempts, once discarded, now preserve the evidence of how Jingdezhen pursued perfection.
For more than 1,000 years, Jingdezhen's porcelain industry has endured through the Song, Yuan, Ming and Qing dynasties (960-1911). What has survived is not only its porcelain, but also a living heritage of raw materials, workshops, kilns and specialized craftsmanship.
Those firings produced masterpieces as well as failures, with the discarded pieces forming another kind of archive.
At the Jingdezhen Imperial Kiln Institute, Weng told archaeology students that fragmented specimens sometimes provide more information than complete artifacts.
Weng leads the development of the world's first Ancient Ceramics Gene Bank, which extracts and catalogs the defining characteristics of each ceramic shard.
"For our institute alone, we have excavated more than 20 million pieces of shards for the past over 1,200 years. Among those shards, we do sorting, we do restoration, and we do scientific tests. And then we find, wow, a small shard can tell us much more information than even a whole piece," said Weng.
Using a standardized sample library and unified data framework, the project records each piece's shape, decoration, body material, glaze, color, firing marks and inscriptions, creating a valuable resource for authentication and research around the world.
"The whole city is a wonderful lab and space range makes Jingdezhen uniquely a wonderful example of how the handicraft ancient industry with porcelain as the focus survived even to today," Weng added.
Jingdezhen once helped establish benchmarks for how porcelain was made. Now, the gene bank is turning fragments into a language that can be read beyond the city. For French artist and researcher Yann Colleu, learning to read that language has also changed the way he creates.
"Since my childhood, my parents had these teapots, tea sets, plates and cups. I was very curious about the pattern, like the meaning, what was behind it? Actually when I discovered in Jingdezhen that it was a bat, because of 'fu' and 'fu' is fortune, but also you have the 'wufu,' like the five blessings. I was like a child with stars in the eyes, discovering the world for the first time," said Colleu, PhD candidate at Jingdezhen Ceramic University.
What once seemed abstract became part of Yann's own visual language. In his work, traditional Jingdezhen motifs and production scenes are reimagined through a contemporary, cross-cultural lens.
"Jingdezhen is a timeless city. The past, the present and even the future are tied together. This is one of illustration of 72 traditional steps developing during the Ming Dynasty (1368-1644). The difference is, instead of using Chinese characters, I use foreigners. I want to use the past to talk about the present and even the future with Jingdezhen," said Colleu.
The Jingdezhen Handicraft Porcelain Industry Sites were inscribed on the UNESCO World Heritage List on Saturday. The inscription recognizes not just a single kiln or masterpiece, but an entire production system, from its archaeological remains and traditional craftsmanship to its industrial knowledge and global influence.
