SANTA BARBARA, Calif., Feb. 07, 2018 (GLOBE NEWSWIRE) -- 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.”
About HyperSolar, Inc.
HyperSolar is developing a breakthrough, low cost technology to make renewable hydrogen using sunlight and any source of water, including seawater and wastewater. Unlike hydrocarbon fuels, such as oil, coal and natural gas, where carbon dioxide and other contaminants are released into the atmosphere when used, hydrogen fuel usage produces pure water as the only byproduct. By optimizing the science of water electrolysis at the nano-level, our low cost nanoparticles mimic photosynthesis to efficiently use sunlight to separate hydrogen from water, to produce environmentally friendly renewable hydrogen. Using our low cost method to produce renewable hydrogen, we intend to enable a world of distributed hydrogen production for renewable electricity and hydrogen fuel cell vehicles.
