Sinopec Completes World’s Largest Electrolyzer

With the completion of its flagship Kuqa electrolyzer in Xinjiang in late June, China's Sinopec has started producing green hydrogen for the first time and has more — and bigger — projects in the pipeline. The company's 3 billion yuan ($410 million) Kuqa plant has the capacity to make 20,000 tons per year of hydrogen from water, using a 250 megawatt electrolyzer powered by solar energy. This is to date the world’s largest operational green hydrogen electrolyzer, surpassing a 150 MW project in China's Ningxia region by coal-based chemicals manufacturer Baofeng that has been in operation since the end of 2021. The Kuqa project serves as a “demonstration” or model for the company to “carve out a new path for green hydrogen refining,” says Sinopec, which is China’s largest refiner.
