As the industry matures, the lifespan of today's dry-grind ethanol facilities is becoming increasingly important. Producing more ethanol now is the order of the day. But as the renewable fuel becomes a mainstay of the United States' transportation fuel infrastructure, can ethanol plants—the physical structures themselves and the equipment within them—last as long as consumer demand for the product?
On first thought, a great place to locate an ethanol plant seems to be where others have labored to lay the groundwork before—on a brownfield site. But the fact is most U.S. ethanol plants, both operating and under construction, choose the greenfield route to project development, effectively discounting the benefits of building brown.
