Corn Stalks and Cobs Into Clean Hydrogen

Hydrogen has several demerits in coming to the energy market.  A primary issue for H2 critics – that hydrogen requires more energy to produce than it gives back – may have been answered by Dr. Percival Zhang of Virginia Tech’s Department of Biological Systems Engineering, which is in both the College of Agriculture and Life Sciences and the College of Engineering.  We’ve covered his work before, usually in terms of turning corn into biofuels or in finding biological ways to produce hydrogen with low energy input. Part of his exploratory mandate comes from his ECHo cycle.  “I wish to suggest constructing the electricity-carbohydrate-hydrogen (ECHo) cycle… could meet four basic needs of humans: air, water, food and energy, while minimizing environmental …
