Washington forests may be solution to state's green-energy quest
Aug 20, 2009 - Sandra Hines - University Week
Wood is a popular fuel for heating homes in the Northwest but few people might see it as an important source of liquid fuels for motor vehicles. However, a new UW report commissioned by the Washington Legislature suggests that woody biomass could represent the state's greatest opportunity to develop biofuels and reduce both green house gas emissions and dependency upon imported oil.
The report by the UW's School of Forest Resources further concludes that the state's biomass would best be used for transportation fuel as opposed to using it to generate electricity.
Woody biomass has three key advantages -- all of which should be weighed no matter which alternative energy source is being evaluated, the report authors say. They are:
In light of these three considerations, state incentives and regulations that encourage generating electrical power from renewable sources such as woody biomass should be examined, says John Calhoun, director of the Olympic Natural Resources Center and a study co-author.
"While wood residue may currently be considered waste," Calhoun says, "Washington must not squander this renewable resource by misdirecting its use if we want to meet our state goals of sustainability, energy independence and climate change mitigation. Woody biomass is the only renewable, clean resource available in Washington that can make a significant contribution toward our energy policy goals."
Another advantage of woody biomass is what's already in place, says Mason. The state's largest biomass process and delivery system is the forest industry. Pulp and paper mills represent the single largest industrial capital investment in renewable energy development. Liquid fuel conversions from woody biomass will require large integrated facilities, such as pulp and paper mills, that, with new investment, could maximize conversion efficiencies and reduce capital and operating costs while producing a steady flow of paper and energy products.
"Co-location with state pulp and paper mills to capture synergies with existing infrastructure represents the greatest single opportunity for bioenergy development. Such mills already have transportation and handling capabilities, a highly-skilled workforce, adequate water supplies and water treatment plants," Mason says.
