HyperSolar Reports Dramatic Power Increase With Its Solar-powered Nanoparticles for Hydrogen Production

(Nanowerk News) HyperSolar, Inc., the developer of a breakthrough technology to produce renewable hydrogen using sunlight and any source of water, today announced that its nanoparticle technology is now capable of producing 0.75 volts of electricity. This achievement represents a dramatic power increase over the previous power output of 0.2 volts.
“We are very pleased with the progress made by our team,” stated Tim Young, CEO of HyperSolar. “Increasing the voltage is the key to achieving commercial success. We now have a clear path forward to reach our goal of open circuit voltage of 1.5 volts with 10% conversion efficiency to cost effectively split water into hydrogen and oxygen. Commercially available solar cells are simply too expensive for water splitting. Our novel nanoparticles are designed to use very low cost and Earth abundant materials to convert sunlight into electricity.”
HyperSolar’s sponsored research program with the University of California, Santa Barbara (UCSB) has achieved important milestones in the company’s nano-size particle development plan. Some of the accomplishments include:
  • Developed a transparent conducting organic material that is electrocatalytically active and stable for solar fuel and chemical production.
  • Demonstrated stable solar water splitting, organic waste oxidation, HBr electrolysis for many hours without the need of any external wiring with only sunlight as the energy input.
  • Demonstrated a novel semiconducting device structure synthesized entirely by electrochemical means that show activity for solar photosynthesis to make fuels and chemicals for many hours without external wiring.
  • Developed novel design strategies to improve open circuit voltages of individual nano structures from 0.2 V to 0.75 V.
  • Mr. Young continued, “An economically viable method of producing truly renewable hydrogen is vital to our future transportation and energy storage needs. We believe that our development efforts hold the key to cost-effective onsite renewable hydrogen production. This hydrogen generation option will be essential for the establishment of fueling stations to power hydrogen automobiles currently in production by Ford, Honda, and other major auto manufacturers. We must still reach additional milestones to achieve economic viability, but our development thus far is very promising.”
    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.
