A demonstration project in Beijing has successfully decomposed hydrogen sulfide (H2S) into high-purity hydrogen and sulfur, addressing environmental challenges associated with H2S emissions from natural gas, petrochemicals, and coal. Developed by a team from the Dalian Institute of Chemical Physics at the Chinese Academy of Sciences, the project can process 100,000 cubic meters of H2S annually.

Collaborators include Shandong Sunway Chemical Group and Haoming Energy Technology. The facility achieves over 99.999% H2S conversion and produces commercially viable hydrogen and sulfur. If utilized for the 8 billion cubic meters of H2S processed annually in China, this technology could recover approximately 730,000 tonnes of low-carbon hydrogen. This innovation supports China's goal of producing 1.8 million tons of green hydrogen by 2030.
