As climate change progresses, researchers worldwide continue to search for clean, sustainable replacements for fossil fuels. One promising alternative is hydrogen, which produces near-zero greenhouse gas emissions when burned.
However, producing hydrogen from renewable resources through electrolysis requires vast amounts of high-purity water. This may aggravate the shortage of freshwater resources, which has already become an urgent problem globally.
Seawater is abundant but must be desalinated before use in commercial electrolyzers.
Now, a team of researchers from China, Australia, and the U.S. has developed a new process that splits seawater without pre-treatment to produce green hydrogen.
The international team was led by the University of Adelaide’s Professor Shizhang Qiao and Associate Professor Yao Zheng from the School of Chemical Engineering.
In the electrolysis of water,…
