China’s large photovoltaic hydrogen project
China Three Gorges Corporation announced a large‑scale photovoltaic hydrogen project with a production target of 10,000 tons per year, positioning it as a net‑zero urban energy benchmark. The project links utility‑scale solar with green hydrogen production, signalling how integrated energy systems are scaling in major infrastructure programmes. (x.com)
Hydrogen is a way to store electricity in chemical form, like pouring solar power into a tank instead of sending it straight down a wire. The basic trick is electrolysis: run electricity through water, and the machine splits it into hydrogen and oxygen. (energy.gov) That only counts as “green hydrogen” if the electricity comes from low-carbon power like wind or solar. China Three Gorges’ project in Ordos pairs a 400 megawatt solar plant with hydrogen equipment so the solar farm feeds the hydrogen plant directly. (chinadaily.com.cn, seetao.com) The project is in Jungar Banner, in the city of Ordos in Inner Mongolia, and it was built by Ordos Hanxia New Energy, a venture backed by China Three Gorges Group and Inner Mongolia Man Shi Group. Construction officially started in August 2022. (seetao.com, thepaper.cn) Its target scale is 10,000 metric tons of hydrogen a year, which is why Chinese outlets keep calling it the country’s first “10,000-ton” photovoltaic hydrogen project. In March 2026, local officials said it had entered large-scale filling operations after completing a 423 kilogram hydrogen fill at 99.999 percent purity. (chinadaily.com.cn, thepaper.cn) Inside the plant, the water-splitting machines are alkaline electrolyzers, which are the older, heavier industrial version of the technology and are widely used because they scale well. This project uses 15 units rated at 1,000 standard cubic meters per hour each, for total hydrogen capacity of 15,000 standard cubic meters per hour. (andritz.com, thepaper.cn, news.metal.com) The solar side matters just as much as the hydrogen side. Local reporting says the photovoltaic station generates about 740 million kilowatt-hours a year, and about 80 percent of that power is used to make hydrogen instead of being sold as ordinary electricity. (spglobal.com, thepaper.cn) This is not a lab demo looking for a use case. The hydrogen is already being trucked to customers, and local officials said sales routes now reach Hohhot, Baotou, Ordos, Datong, Shenmu, and nearby industrial parks in Shanxi and Shaanxi. (thepaper.cn) Those customers are not just fuel stations. The same local report said green hydrogen from the project is being lined up for silicon materials, ammonia, methanol, and other chemical uses, which is where hydrogen demand is already large enough to absorb industrial volumes. (thepaper.cn) The other thing this project shows is geography. The solar farm sits in a coal-mining subsidence backfill area, while the hydrogen plant sits roughly 60 kilometers away in an industrial park, and Chinese reports describe that link as a domestic first for long-distance integrated solar-to-hydrogen design. (thepaper.cn, chinadaily.com.cn) China has announced plenty of hydrogen pilots, but this one matters because it has moved from “planned capacity” to actual product leaving the gate. By February and March 2026, China Daily and local officials were describing it as operating smoothly and beginning large-scale filling, which is the point where an energy project stops being a slide deck and starts being infrastructure.
