New Device Harnesses Sun and Sewage to Produce Hydrogen Fuel

October 17, 2013 |

In California, a research team at the University of Santa Cruz have developed a solar-microbial device and reported their results in a paper published in the American Chemical Society journal ACS Nano. The hybrid device combines a microbial fuel cell and a type of solar cell called a photoelectrochemical cell that can use sunlight and wastewater to produce hydrogen gas.

The researchers are optimistic about the commercial potential for their invention. Currently they are planning to scale up the small laboratory device to make a larger 40-liter prototype continuously fed with municipal wastewater. If results from the 40-liter prototype are promising, they will test the device on site at the wastewater treatment plant.
