China’s first seawater project

On December 16, Sinopec proudly announced the completion of China’s first industrial-scale seawater-to-hydrogen research project in Qingdao. This groundbreaking initiative represents a giant leap in the country’s transition to clean energy and a sustainable future.

The project leverages cutting-edge technology, combining direct seawater electrolysis with green electricity sourced from Qingdao Refining and Chemical’s floating photovoltaic power station. Splitting seawater into hydrogen and oxygen eliminates the need for desalination—a critical advancement. The green hydrogen produced is seamlessly integrated into refining processes or used for hydrogen-powered vehicles.

Key technological challenges, such as chlorine-resistant electrodes, advanced bipolar plate design, and innovative seawater circulation systems, were successfully addressed. The project also explores new avenues for utilizing high-salinity industrial wastewater, offering a model for resource-efficient hydrogen production in coastal regions.

By merging seawater electrolysis with renewable energy, this project not only significantly reduces carbon emissions but also sets a global precedent for large-scale hydrogen production. It aligns perfectly with China's vision of a green, low-carbon future, driving innovation in the hydrogen energy industry and expanding renewable energy's potential.
