HyperSolar Announces Impressive Catalyst Stability for Solar Hydrogen Production
Company's proprietary low-cost 3D oxygen electrocatalyst maintains stability for over 190 hours with no loss of efficiency
SANTA BARBARA, CA - February 7, 2018 - HyperSolar, Inc. (OTCQB: HYSR), the developer of a breakthrough technology to produce renewable hydrogen using sunlight and any source of water, announced today a significant improvement of its proprietary low-cost 3-dimensional oxygen catalyst.
The amount of hydrogen produced by water splitting is fundamentally limited by the slower oxygen half reaction. Developing an efficient and stable oxygen catalyst is an important milestone in the Company's effort to split water molecules for the production of renewable hydrogen. Recent catalyst optimization and performance testing by HyperSolar and the University of Iowa demonstrated its high efficiency oxygen catalyst working for over 190 hours, and still running without loss of efficiency. In comparison to existing state-of-the-art photo-electrochemical technologies, this represents a significant advancement in terms of stability for catalysts made of entirely inexpensive earth abundant elements.
'Solar hydrogen production is challenged by the efficiency of the catalyst and the solar cell, and the risk of their instability in the harsh water conditions of photo-electrochemical reactions,' said Dr. Joun Lee, CTO of HyperSolar.' 'This successful development of the 3D catalyst is an important milestone for achieving high hydrogen production efficiency for a long period of operation, which contributes to lowering the hydrogen production cost. We are now in the process of further proving the stability of the 3D oxygen catalyst in a fully integrated solar-to-hydrogen device. We expect the device-level stability to be over 190 hours as well since the oxygen reaction is the primary limiter of device-level performance.'
This catalyst is designed for the Company's first generation hydrogen system that uses commercially available and inexpensive amorphous triple junction silicon solar (a-Si) cells.
Tim Young, CEO of HyperSolar, commented, 'Our goal with the a-Si system is to demonstrate at least 365 hours of stable hydrogen production under intensive operating conditions. By doing so, we will have simulated one year of operating life of our technology, which we believe will make our technology commercially attractive in various hydrogen markets. We believe that 1 year of stable operation can make conventional electrolyzer-based renewable hydrogen obsolete, and open up new markets due to our lower cost.'
