Hydrogen is as clean a fuel as they come… or not. Although it emits very little greenhouse gas, more than 90% of it is currently produced from fossil sources at a high cost. Virginia Tech scientists claim that is soon to be a thing of the past. They were able to produce hydrogen from waste products of corn. Their efficient enzymatic process is inexpensive, and could be conducted at a production facility the size of a regular gas station. Their vision? Distributed and affordable green hydrogen from local biomass resources will displace fossil fuels in vehicles. Stay tuned.
