Book excerpt: 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 considers successes and lessons learned from current wood energy systems in Alaska, and also considers opportunities for future bioenergy development.

This book was released on 2016 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, wood-energy use in Alaska has grown dramatically. Since 2000, several dozen new wood-energy installations have been established, with numerous others in the design or construction phase. This case study report compares two wood-pellet heating systems in Juneau, Alaska. The Tlingit-Haida Regional Housing Authority, a native housing authority that serves more than 27,000 tribal residents in 11 communities in the southeast, recently established a wood-pellet boiler to provide heating to their 10,000-square-foot warehouse. The Sealaska Corporation is an Alaska Native Corporation that recently installed a wood-pellet system to heat its 58,000-square-foot office building in downtown Juneau. In this case study, we consider the ongoing efforts of both organizations to advance wood energy in southeast Alaska. We review the wood energy conversion process--including the motivation for change, feasibility work, construction, system operation, and lessons learned.

This book was released on 2015 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, the use of wood for thermal energy in Alaska has grown significantly. Since 2000, nearly 30 new thermal wood-energy installations in Alaska have been established. Cordwood units, burning primarily firewood and other forms of roundwood, have played an integral part in this success and are well suited to many rural communities in Alaska. In this case study, we evaluate cordwood installations located in three geographic regions of Alaska. Included are systems at Coffman Cove (southeast Alaska), Ionia (Kenai Peninsula, Alaska), and Gulkana (south-central Alaska). We considered the wood-energy conversion process, system operation, economics, and carbon benefits of the three cordwood systems. We found that the simple payback period ranged from 1.1 to 14.2 years and the internal rate of return from 8 to 91 percent, and that benefits exceeded costs by a factor of from 1.6 to 17. There were also substantial carbon benefits for cordwood systems. Carbon dioxide (CO2) emissions (relative to those from heating oil) differed by installation from 129 to 259 tons avoided per year, with total reductions of 611 tons of CO2 per year. We also considered secondary benefits of community-scale cordwood energy systems in rural Alaska, including greenhouses for local foods, the ability to create part-time jobs for local residents, and the educational experiences for school students.
