The bacteria is grown in anaerobic conditions and then used to metabolize sugars that are converted to hydrogen and carbon dioxide. They pass the gas that's produced through a sodium hydroxide solution that absorbs the carbon dioxide, leaving just the hydrogen. The researchers used switchgrass combined with a solution of grape juice waste as the feedstock. They found that the combination produced three times as much hydrogen as the switchgrass or grape juice alone. Nanologix believes that this is a major advance in making mass hydrogen production more viable.
The process is flexible and adapts to other biomass feed stocks and the bacteria are easily cultured. Biological processes like this should require much less energy input then any traditional production methods. These kinds of processes can also use biomass that can be grown in a wide variety of environments without detracting from food production as well as using organic waste materials.
