On May 16, 2012 I had talked about HyperSolar Inc.’s new sunlight plus water equals hydrogen breakthrough technology that seems like it could be a breakthrough in the field. The solar cells are actually in the water where electrolysis takes place.
And since the solar cells have a low cost polymer coating, any kind of water including waste water can be used to produce hydrogen. The seemed, at the time, almost too good to be true.
But yet now HyperSolar has kicked it up a notch with an end to end lab scale demonstration proof of concept. You can watch the Youtube video here.
According to HyperSolar’s CEO Tim Young, “Using our self-contained particle in a low cost plastic bag, we have successfully demonstrated our ability to mimic photosynthesis to produce renewable hydrogen from virtually any source of water using the power of the Sun. Unlike approaches taken by others in the past, our small scale solar devices actually float in the water. Our next step is to complete the development of our nanoparticles, extremely small solar devices, optimized to significantly reduce the cost of separating hydrogen from water.”
Admittedly after watching the video one may be underwhelmed since this is still a basic science experiment of sorts. But the implications are huge. If this technology can be scaled up and used globally this would mean that hydrogen could be produced anywhere, anytime there is sunlight and some sort of water source even water that is not pure enough to drink.
