HyperSolar has announced that its artificial photosynthesis technology is now capable of producing 1.2 volt open circuit voltage for use in direct solar hydrogen production.
This achievement represents another 10% increase over the previous 1.1 volt reached late last year, a significant step towards truly renewable low cost hydrogen.
“We now see a path to production of hydrogen through immersion of low cost semiconductor materials in water,” stated Tim Young. “Our approach uses only one type of inexpensive semiconducting material and reduces manufacturing complexity. Use of low cost materials with an industrial scaleable process and may even make it a viable approach for fabricating low-cost photovoltaic modules for other applications beyond water splitting.”
“With the recent announcements of Hyundai, Honda, Toyota and other major auto manufacturers to begin shipping hydrogen fuel cell cars next year, there will be increased demand in the near future for clean hydrogen,” continued Mr. Young. “We believe our technology can address two serious drawbacks impeding major adoption of hydrogen automobiles: First, the lack of hydrogen production infrastructure near the point of distribution or the fueling stations is addressed by our solar hydrogen production process. Second, hydrogen is currently produced from a fossil fuel — natural gas — in a process that releases substantial amounts of carbon dioxide into the atmosphere.”
