HyperSolar Announces Record Results for its Proprietary Catalyst and Solar Hydrogen Generator

SANTA BARBARA, Calif., April 09, 2018 -- HyperSolar, Inc. (OTCQB:HYSR), the developer of a breakthrough technology to produce renewable hydrogen using sunlight and any source of water, announced today preliminary results from the past month of testing, ones that demonstrate overall success thus far for the durability of the catalyst, and record-breaking stability of the entire device.

As previously announced, HyperSolar commenced performing a series of tests on its proprietary, earth-abundant oxygen evolution catalyst that previously demonstrated stability under alkaline water for more than 190 hours. During a test that remains ongoing, HyperSolar and the University of Iowa have achieved over 870 hours of stable operation of the proprietary earth-abundant oxygen catalyst under alkaline water. Previously, the oxygen catalyst was one of the least stable components in the integrated GEN 1 device, a close replica of how a large-scale solar-hydrogen generator would appear and perform when commercialized. Successful long-term stability of the oxygen catalyst approaching 1000 hours will enable highly robust and stable operation of GEN 1 device under alkaline water. GEN 1 is the Company’s planned first generation solar-hydrogen device based on commercially available amorphous silicon triple-junction solar cells.  

During testing of the all-in-one, wireless solar-hydrogen device, HyperSolar observed over 100 hours of stable operation under continuous simulated sunlight illumination, establishing what the Company believes is a new international record for wireless self-contained solar hydrogen device. The device produced oxygen and hydrogen until part of the solar cell began to degrade after 105 hours. The team believes it has identified the problem and will implement a strategy to further improve the stability for longer run time.

“We are extremely pleased by the positive results surrounding the stability of the oxygen catalyst, a critical component of our design for meeting the efficiency requirements of real world applications,” said Tim Young, CEO of HyperSolar. “We are also encouraged by the initial success of the stability test for the full device. While the device started to degrade after 105 hours, we are confident that we can fix these issues, resume testing, and ultimately demonstrate commercial viability.”

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.  To learn more about HyperSolar, please visit our website at www.hypersolar.com.
