Fuel made from wood could become a competitive commercial alternative to fuel made from corn by 2020 if the wood biofuel industry is supported, according to a new University of British Columbia study.
Corn ethanol is currently blended with gasoline to satisfy government-mandated targets to include renewable content in transportation fuel. Compared to corn, wood-based biofuel is considered more sustainable but is not currently produced in large commercial quantities in Canada and the United States because the costs are too great.
The study, published in the most recent issue of the journal Biofuels Bioproducts & Biorefining, identifies several opportunities for reducing these costs. Researchers in UBC's Faculty of Forestry found that large-scale commercial production of wood-based ethanol, also known as cellulosic ethanol, will reduce capital and operation costs and assist in achieving the improvements necessary for wood-based ethanol to compete, without government support.
"As industrial production increases, cellulosic ethanol is likely to become more competitive with corn ethanol for a share of the renewable fuels market," says Jamie Stephen, a PhD candidate at UBC and lead author of the study.
Stephen's research indicates that the economic competitiveness of wood-based ethanol fuel production could be improved by reducing the capital costs of facilities and equipment, reducing enzyme costs and generating revenue from co-products like electricity. Today, the enzymes needed to breakdown wood products one of the major costs associated with production. As industrial volumes of biofuel are produced and demand grows, technological learning and economies-of-scale will help reduce the cost.
The 2007 Energy Independence and Security Act in the United States requires that 117 billion litres (31 billion gallons) of ethanol be added to gasoline annually by 2022. In Canada, the federal government mandates that gasoli
