Influence of policy, air quality, and local attitudes toward renewable energy on the adoption of woody biomass heating systems

Publications Posted on: November 21, 2018
Heat produced from woody biomass accounts for a significant portion of renewable energy in the United States. Economic and federal policy factors driving institutional adoption of woody biomass heating systems have been identified and examined in previous studies, as have the effects of state policies in support of biomass heating.

Burgeoning biomass: Creating efficient and sustainable forest biomass supply chains in the Rockies

Pages Posted on: April 11, 2018
Woody biomass could be used to generate energy in the western U.S. if the utilization process is both economically feasible and ecologically sustainable. The purpose of the RMRS-led Biomass Research and Development Initiative (BRDI) is to develop technologies, approaches, and new science that will help to make this possible. This issue of the Bulletin is focused on research addressing challenges of the biomass supply chain, from the time that a forest treatment is initiated to the time that the biomass residue reaches an end user (a later issue will address the technology of biomass conversion after the material is delivered). A major roadblock to effective biomass utilization is the high handling costs and low market value of woody biomass. As part of this project, new technologies are being developed to enhance biomass resources assessment, improve supply chain logistics, and reduce handling costs through equipment modification and more efficiently managing operations in forest treatment areas. and quickly assessing forest biomass supplies, new and innovative tools are now available.

Technoeconomic and policy drivers of project performance for bioenergy alternatives using biomass from beetle-killed trees

Publications Posted on: February 12, 2018
As a result of widespread mortality from beetle infestation in the forests of the western United States, there are substantial stocks of biomass suitable as a feedstock for energy production. This study explored the financial viability of four production pathway scenarios for the conversion of beetle-killed pine to bioenergy and bioproducts in the Rocky Mountains.

Economic and policy factors driving adoption of institutional woody biomass heating systems in the United States

Publications Posted on: January 09, 2018
Abundant stocks of woody biomass that are associated with active forest management can be used as fuel for bioenergy in many applications. Though factors driving large-scale biomass use in industrial settings have been studied extensively, small-scale biomass combustion systems commonly used by institutions for heating have received less attention.

Social preferences toward energy generation with woody biomass from public forests in Montana, USA

Publications Posted on: December 13, 2016
In Montana, USA, there are substantial opportunities for mechanized thinning treatments on public forests to reduce the likelihood of severe and damaging wildfires and improve forest health. These treatments produce residues that can be used to generate renewable energy and displace fossil fuels.

Wood bioenergy and soil productivity research

Publications Posted on: April 18, 2016
Timber harvesting can cause both short- and long-term changes in forest ecosystem functions, and scientists from USDA Forest Service (USDA FS) have been studying these processes for many years. Biomass and bioenergy markets alter the amount, type, and frequency at which material is harvested, which in turn has similar yet specific impacts on sustainable productivity.

Science You Can Use Bulletin: Burgeoning biomass: Creating efficient and sustainable forest biomass supply chains in the Rockies, Part II

Publications Posted on: January 12, 2016
Woody biomass could be used to generate renewable bioenergy and bioproducts in the western U.S. and has the potential to offer environmental and societal benefits. The purpose of the Rocky Mountain Research Station-led Biomass Research and Development Initiative (BRDI) project is to research and develop technologies, approaches, and new science that will help to make this possible.

Financial performance of a mobile pyrolysis system used to produce biochar from sawmill residues

Publications Posted on: October 05, 2015
Primary wood products manufacturers generate significant amounts of woody biomass residues that can be used as feedstocks for distributed-scale thermochemical conversion systems that produce valuable bioenergy and bioproducts. However, private investment in these technologies is driven primarily by financial performance, which is often unknown for new technologies with limited industrial deployment.

Characterization of fast pyrolysis products generated from several western USA woody species

Publications Posted on: July 08, 2015
Woody biomass has the potential to be utilized at an alternative fuel source through its pyrolytic conversion. Here, fast pyrolysis bio-oils derived from several western USA woody species are characterized by negative-ion electrospray ionization Fourier transform ion cyclotron resonance mass spectrometry (ESI FT-ICR MS) to determine molecular-level composition.
