‘Inexhaustible’ Source of Hydrogen May Be Unlocked by Salt Water, Engineers Say
Oh what’s that science? More renewable energy that isn’t as environmentally destructive as the traditional nuclear?
A grain of salt or two may be all that microbial electrolysis cells need to produce hydrogen from wastewater or organic byproducts, without adding carbon dioxide to the atmosphere or using grid electricity, according to Penn State engineers.
“This system could produce hydrogen anyplace that there is wastewater near sea water,” said Bruce E. Logan, Kappe Professor of Environmental Engineering. “It uses no grid electricity and is completely carbon neutral. It is an inexhaustible source of energy.”
Microbial electrolysis cells that produce hydrogen are the basis of this recent work, but previously, to produce hydrogen, the fuel cells required some electrical input. Now, Logan, working with postdoctoral fellow Younggy Kim is using the difference between river water and seawater to add the extra energy needed to produce hydrogen.
Their results, published Sept. 19 in the Proceedings of the National Academy of Sciences, “show that pure hydrogen gas can efficiently be produced from virtually limitless supplies of seawater and river water and biodegradable organic matter.”
