OK, we'll let a non-hydrogen story slip by here at the end of the day. While the National Hydrogen Association is excited to have 32 hydrogen fueling stations open across the country, that's nothing compared to the 101 ethanol plants now in operation across the U.S. These plants can produce 4744.9 mmgy (million gallons per year), according to Renewable Fuels Association. The one-hundredth plant was opened in Iowa by Frontier Ethanol. The ethanol boom isn't stopping any time soon. The RFA lists 32 new plants and 8 plant expansions that will bring America's total ethanol production capacity to 6770.4 mmgy.
