NREL Equips Biorefineries with Procedure to Boost Cellulosic Ethanol Production NREL researchers invented an easy method to measure the amount of cellulose in corn grain samples, helping ethanol refiners unlock incentives to investment. Photo credit: Dennis Schroeder, NREL Federal incentives can help ethanol refiners expand their plants into generation 1.5 biorefineries designed to make ethanol from both the cellulose and starch sugars found in corn grain. To apply for such support, however, biorefiners need a robust but simple analytical process for measuring the amount of cellulose in their grain. With support from the U.S. Department of Energy Bioenergy Technologies Office, National Renewable Energy Laboratory (NREL) scientists have unveiled a new analytical method to give companies an unprecedented level of ease and precision. By completely removing starch from grain samples using special enzymes, NREL's method sidesteps inaccuracies present in current analytical methods.
