Objectives

• Define woody biomass

• Define bioenergy

• Explain the benefits of using woody biomass for bioenergy

• Describe the role woody biomass plays in global bioenergy production


Outline

• Availability

• Utilization

• Biomass in the United States

• Benefits

• Promotion


What is Woody Biomass?

• Woody biomass is the accumulated mass, above and below ground, of the wood, bark, and leaves of living and dead woody shrubs and trees.


What is Bioenergy?

• Energy produced from biomass including woody biomass, agricultural biomass, and other biological materials

• Includes electricity, heat, and transportation fuels


Availability of Biomass

• OECD – commercial, industry-led

• Asia and Latin America – modern, commercial

• Africa – harvested informally

China20.5%

Asia(excluding

China)34.2%

Latin America7.0%

Africa23.9%

OECD13.0%

Middle East 0.1%

Former USSR 0.9%

Non-OECD Europe 0.4%

Biomass & Forest Products

• Forest products industry is largest user of forest biomass– 70% of energy in-house– Created from by-products


Biomass & Forest Products


Benefits of Biomass

• Environmental Benefits

• Economic Benefits

• Energy Benefits


Environmental Benefits• Carbon

sequestration• Reduced

greenhouse gas emissions


Environmental Benefits

• Forest health– Reduce wildfire risk– Reduced mortality due

to insect and disease– Recovery of degraded

land


Economic Benefits• Landowners

– Increased income potential

– Reduced site preparation costs

• Communities– New markets for

forest products– Economic

diversification


Energy Benefits

• Reduced fossil fuel use

• Renewable source

• Improved energy security


Energy Potential

• Forest residues

• Ethanol potential

• Southern advantage

Promoting Biomass

• Market Formation– Bioenergy systems– Biofuels

• Challenges


Market Formation• System-level focus across entire value chain

– Biomass production

– Harvesting, transport, processing

– Utilization and energy generation capacity• Direct combustion

• Conversion technology

– Consumer demand

• Marketing messages– Reliable and affordable

– Enables secure energy future


Biofuels Opportunities

• Solid fuels– Pellets, briquettes

• Liquid fuels– Ethanol– Bio-diesel


Challenges in Bioenergy

• Supply and Market Development

• Integration

• Competitiveness and Mainstreaming

• Sustainability


Creating Synergies

• Energy sector– Greater use of by-products for fuel– Sale of excess electricity to the grid

• Agriculture– Cooperate in market development for ethanol


Conclusions• Forest biomass is an attractive renewable

energy source.

• It provides environmental, economic, and energy benefits to society.

• Challenges and barriers do exist.– Market development– Collaboration– Education
