China has completed construction of its first plant-scale research project for producing hydrogen from seawater, Sinopec announced on Wednesday.
The project, located in Qingdao in the eastern province of Shandong, combines the direct electrolysis of seawater with the production of hydrogen from green electricity. It produces 20 cubic meters of green hydrogen per hour, according to the company.

Operating in a factory environment, the project uses green electricity generated by the offshore photovoltaic plant of Sinopec Qingdao Refining & Chemical Co, Ltd.
Seawater is separated into hydrogen and oxygen by specialized electrolyzers. The hydrogen produced is integrated into the company’s gas pipeline network, where it is used for refining operations or to fuel hydrogen vehicles, according to the company.
Green hydrogen, produced from renewable energy sources, such as solar and wind, emits virtually no greenhouse gases during its production.
Direct electrolysis of seawater converts unstable green electricity into green hydrogen, which is easier to store and transport. It also helps preserve fresh water and advance the hydrogen energy industry.
