Seawater-Based Hydrogen Production Methods

Chung-Ang University researchers, led by Assistant Professor Haeseong Jang, have developed a sustainable method for producing hydrogen using seawater, addressing critical barriers to clean energy adoption.

Hydrogen is widely viewed as a promising alternative fuel thanks to its high energy density and zero carbon emissions. While alkaline water electrolysis is efficient and eco-friendly, it depends on freshwater, limiting its scalability. Seawater, an abundant resource, offers a solution, but high chloride concentrations corrode catalysts and reduce efficiency.

To overcome this challenge, the Chung-Ang University team, in collaboration with Professor Xien Liu at Qingdao University of Science and Technology, created a durable and cost-effective electrocatalyst capable of supporting efficient hydrogen production in saline environments. Their breakthrough improves reaction performance while resisting corrosion, making the process more stable and economically viable. This innovation advances large-scale hydrogen generation while conserving freshwater resources, contributing to a more sustainable and resilient global energy future.
