Cellulosic biofuel producers are racing to commercialize, but for their products to survive, they will need to compete on cost and performance with petroleum fuels. The economics are still uncertain. Lux Research built a detailed cost model to analyze five main routes from lignocellulosic biomass to sugars: dilute acid, ammonia fiber expansion, steam explosion, supercritical fluid, and concentrated acid. We asked Lux’s Andrew Soare about the prospects for the cellulosic market, and where it fits into the larger biofuels picture.
