NewHydrogen, formally BioSolar, is focusing on developing an oxygen catalyst for proton exchange membrane (PEM) electrolysers that replaces the precious metal iridium with low-cost materials.
This comes with the news that the company has executed a new sponsored research agreement with the University of California at Los Angeles (UCLA) that has expanded research efforts significantly.
The objective of the research agreement is to develop inexpensive and robust materials with an outstanding ability to catalyse the electrochemical oxygen evolution reaction (OER) while achieving overall high-performance water electrolysis for hydrogen production.

Spencer Hall, Chief Operating Officer at NewHydrogen, commented, “We are very pleased to see the progress being made in our green hydrogen program at UCLA.”
“We have great confidence in Dr. Huang and her team and are very pleased with what they have accomplished in such a short period of time.”
“While these updates are more technical in nature, we will continue to make the public and broader capital markets aware of the technology objectives and critical steps of the process.”
NewHydrogen gave further insight into its research stating that a baseline non-precious metal based OER catalyst was selected and optimised for preliminary evaluations.
The catalyst was then successfully synthesised upon adjusting its physical parameters and conditions to exhibit the best material characteristics.
At each iteration, the catalyst material was characterised using transmission electron microscopy (TEM) and X-ray diffraction (XRD) studies.
Electrochemical tests were also performed to confirm that the catalyst material indeed was a good reference point for further improvement.
Comprehensive testing of the baseline catalyst material gave the researchers high confidence that there would be ample room for further improvement by substituting part of the existing metal element in the baseline material structure.
