Description: Biomass resources in Alaska are extensive and diverse, comprising millions of acres of standing small-diameter trees, diseased or dead trees, and trees having lowgrade timber. Limited amounts of logging and mill residues, urban wood residues, and waste products are also available. Recent wildfires in interior Alaska have left substantial volumes of burned timber, potentially usable for biomass energy. Motivated,in part, by rising fuel prices, organizations across the state--including businesses, schools, and government agencies--have all expressed an interest in wood energy applications. Numerous sites have pursued feasibility studies or engineering design analysis, and others have moved forward with project construction. Recent advances in biomass utilization in Alaska have been enabled by numerous factors, and involve various fuel sources, scales of operation, and end products. Already, thermal wood energy systems are using sawmill residues to heat lumber dry kilns, and a public school heating system is in operation. Management policies on national forests and state forests in Alaska could determine the type and amounts of available biomass from managed forests, from wildland-urban interface regions, and from salvage timber operations. Biomass products in Alaska having potential for development are as diverse as wood pellets, cordwood (firewood), compost, wood-plastic composite products, and liquid fuels. In addition, new technologies are allowing for more efficient use of biomass resources for heating and electrical generation at scales appropriate for community power. This case study review onsiders successes and lessons learned from current wood energy systems in Alaska, and also considers opportunities for future bioenergy development.

Keywords: Alaska, biomass, bioenergy, wood energy, renewable, cordwood, sawmill residues.
