Researchers at the University of Colorado Denver College of Engineering and Applied Science have discovered a way to simultaneously desalinate water, produce hydrogen and treat wastewater. “Ships and their crews need energy generated on-site as well as fresh drinking water. Thus, the Navy is very interested in both low energy desalination and renewable energy production,” said Zhiyong (Jason) Ren.
Ren and his team with the University of Colorado Denver discovered, after six months from the initial hypothesis to completion, that they could produce hydrogen gas, which is collectable and storable, thus making improvements in the technology of water purification.

A recent study by Logan group at Penn State University also demonstrated similar findings in that the energy contained in hydrogen gas not only can offset the energy used for the desalination process but has surplus that can be used for downstream processing.
Next steps for Ren and his team will include using real wastewater to test the efficiency as well as optimizing the reactor configuration to improve system performance. “This discovery is a milestone for our new research group,” said Ren. “We are very excited about our findings and will continue working to improve the technology.”
