Hydrogen Extraction from Wastewater (20130046, Dr. William Arnold)
Energy Production from Hydrogen in Wastewater
Hydrogen extraction from wastewater for use as energy is possible with a recent University of Minnesota innovation. The system includes a membrane laden with hydrogen-generating bacteria. The hydrogen is then passed into hollow fibers for removal and can be utilized by fuel cells for energy production. The process does not require costly wastewater aeration at the time of disposal, is modular and can be altered to fit many liquid waste streams including industrial, agricultural, and sanitary waste.
Wastewater is a nutrient-filled and energy-dense substance that is costly to remove from industrial circumstances. There exists a large market for exploiting wastewater for its chemical energy. However, current methods of exploiting wastewater are harmful to the environment and expensive. These methods still require resource-intensive aeration of the exploited water at the time of disposal.
