Eco Factor: Wastewater-munching microbes used to generate hydrogen for fuel cells.
It was just last week that we told you about the Victoria University student producing steam, water, acetic acid and fertilizer from wastewater. This time around, it’s the Arizona State University’s Biodesign Institute that takes it a little further by using this underutilized resource to advance in microbial fuel cell research.
The Biodesign Institute has found a way of using wastewater as a feedstock to generate hydrogen for fuel cells. Its process includes microbial fuel cells that use wastewater munching microbes as a means of liberating electrons, which can further be used to produce current and generate clean energy.
In order to obtain hydrogen in an eco-friendly manner, all that is required is a minor reconfiguring in the devices to support electrolysis. This green production of hydrogen can lead to reduced reliance on natural gas and other fossil fuels, eliminating carbon emissions.
