China's green fuel sector achieved a historic milestone last week as a vessel carrying 3,750 metric tons of green ammonia set sail from Lianyungang Port in East China's Jiangsu province bound for South Korea, marking the nation's largest single-batch export of the zero-carbon energy to date.

Produced by State Power Investment Corp, the shipment represents the first time Chinese green fuel has gained international market recognition based on its full lifecycle carbon reduction contributions.

The delivery signifies that China's entire wind-solar-hydrogen-ammonia industrial chain has officially upgraded from technical demonstration to large-scale international commercial delivery, the company said.

Completed and commissioned in July 2025, the green energy-producing facility is supported by 800,000 kilowatts of installed renewable energy capacity. It stands as the world's largest single-unit green ammonia plant with an annual output capacity of 32,000 tons of green hydrogen and 180,000 tons of green ammonia, it said.

Long utilized as a vital component in fertilizers, ammonia is now gaining traction as a viable low-carbon fuel for the shipping industry. However, conventional ammonia is largely produced using coal and natural gas, which fails to take advantage of its green-energy potential.
