SunHydrogen shared today (July 19) it has experienced positive progress in scaling its nanoparticle-based green hydrogen technology.
SunHydrogen, in cooperation with Schmid Group and InRedox, is developing its technology, that is able to produce hydrogen using sunlight and water, to commercial scale.
Within this cooperation, Schmid is developing the process and equipment for manufacturing while InRedox is focused on the electrochemical process of creating nonporous templates on transparent substrates for growing nanoparticles.
SunHydrogen shared that, after testing several alternative surfactants, its University of Iowa team has successfully identified a biodegradable and environmentally benign substitute that can be added to the plating bath to grow semiconductors without compromising quality.
The University of Iowa research team has also continued to improve the electrochemical process for depositing semiconductors.
The current photoelectrochemical density achieved under laboratory conditions (without catalysts) could potentially result in a maximum solar-to-hydrogen efficiency slightly greater than 17%.
Tim Young, CEO of SunHydrogen, said, “Our research team at the University of Iowa has made the chemistry for manufacturing our nanoparticle technology more environmentally benign without sacrificing the quality of the semiconductors.
“Our process is one step closer to being commercialisable.”
