The very first commercial-scale cellulosic ethanol gallons flowed from the Quad County Corn Processors (QCCP) distillation unit in Galva, Iowa this week, made from a “bolt-on” process that allows a plant to convert the kernel’s corn fiber into cellulosic ethanol, in addition to traditional corn starch ethanol.
“Our Adding Cellulosic Ethanol (ACE) project will not only increase our plant’s production capacity by 6 percent, but it will also continue to boost energy security and provide consumers with more low-cost, cleaner-burning ethanol without adding any additional corn to the production process,” said QCCP CEO Delayne Johnson, who also noted the new technology will improve the plant’s distillers grains (DDGs) co-product. “As a result of the new process, the DDGs will be much more similar to a corn gluten meal. It will increase the protein content of the livestock feed by about 40 percent, and we also expect to see a boost in corn oil extraction by about 300 percent,” he said.
Oddly enough, within 24 hours after Quad County made that announcement, the Environmental Protection Agency gave its final blessing to allow crop residue such as corn fiber to qualify as a fuel pathway for the production of cellulosic biofuel. EPA decided that crop residue actually does meet the lifecycle greenhouse gas (GHG) reduction requirements for cellulosic biofuel under the Renewable Fuel Standard (RFS) provided that “producers include in their registration specific information about the types of residues which will be used, and record and report to EPA the quantities and specific types of residues used.”
“Cellulosic ethanol and corn ethanol are not mutually exclusive,” says Renewable Fuels Association president and CEO Bob Dinneen. “There are synergies that will make the production of both at existing facilities very attractive.”
Cellulosic ethanol is no longer a “phantom fuel” and corn is helping it become a reality.
