Hyper­So­lar Granted Crit­i­cal Patent for Pro­duc­ing Low Cost Re­new­able Hy­dro­gen

Chemical Industry Digest - - News & Views -

Hyper­So­lar, Inc. the de­vel­oper of a break­through tech­nol­ogy to pro­duce re­new­able hy­dro­gen, us­ing sun­light and any source of wa­ter, an­nounced that it was is­sued Patent No. 10100415 from the United States Patent and Trade­mark Of­fice for “Multi-junc­tion ar­ti­fi­cial pho­to­syn­thetic cell with en­hanced pho­to­volt­ages.”

The patent is crit­i­cal to pro­tect­ing the in­tel­lec­tual prop­erty re­lated to the de­vel­op­ment of Hyper­So­lar’s GEN 2 tech­nol­ogy, a po­ten­tially very low-cost re­new­able hy­dro­gen tech­nol­ogy. This patent is jointly owned by Hyper­So­lar and the Re­gents of the Univer­sity of Cal­i­for­nia, as a re­sult of the col­lab­o­ra­tion with the Univer­sity of Cal­i­for­nia, Santa Bar­bara in de­vel­op­ing the tech­nol­ogy.

The patent pro­tects the Com­pany’s pro­pri­etary de­sign of a self-con­tained high voltage so­larto-hy­dro­gen de­vice made up of bil­lions of so­lar-pow­ered wa­ter-split­ting nanopar­ti­cles, per square cen- time­ter. These nanopar­ti­cles con­sist of mul­ti­ple lay­ers of so­lar cells stacked on top of each other to in­crease the pho­to­volt­ages for higher so­lar-to-hy­dro­gen con­ver­sion ef­fi­ciency.

The im­por­tant as­pect of the patented tech­nol­ogy is the in­te­grated struc­tures of high-den­sity ar­rays of nano-sized high voltage so­lar cells as the core of hy­dro­gen pro­duc­tion units. The nanopar­ti­cles can be pro­duced on ul­tra-thin sheets through a roll-to-roll process which re­quires sub­stan­tially lower ma­te­ri­als cost and man­u­fac­tur­ing cost com­pared to con­ven­tional so­lar cells used in rooftop power ap­pli­ca­tions. Fur­ther, the man­u­fac­tur­ing process uses low phys­i­cal and car­bon foot­print and max­i­mizes raw ma­te­rial uti­liza­tion.

This GEN 2 tech­nol­ogy is de­signed from the ground up to be ex­tremely low cost. The Com­pany be­lieves it has the po­ten­tial to pro­duce “green” re­new­able hy­dro­gen to re­place “brown” hy­dro­gen made from the steam re­form­ing of nat­u­ral gas, the pri­mary gen­er­a­tion method used to power the fast-grow­ing hy­dro­gen fuel-cell trans­porta­tion sec­tor for cars, trucks, busses and trains.
