2. OBJECTIVES
Learn about the pros and cons of biomass energy and it sustainability
Learn about the production and implementation of biomass energy
Learn about technical aspects of biomass and how they can be overcome
Learn about the regulations impacting biomass use
Develop an educated opinion about the sustainability of biomass as an alternative energy

3. OVERVIEW
Biomass is a renewable energy source that is derived from living or recently living organisms.
Biomass includes biological material, not organic material like coal.
Energy derived from biomass is mostly used to generate electricity or to produce heat.
Thermal energy is extracted by means of combustion, torrefaction, pyrolysis, and gasification.
Biomass can be chemically and biochemically treated to convert it to a energy-rich fuel.

7. Potential Energy Source?
California produces more than 60 million bone dry tons of biomass each year.
5 million bone dry tons are now burned to make electricity
If it were all used, the 60 million tons could make close to 2,000 megawatts of electricity
Would give enough energy to power 2 million homes
About 6% of Canada’s energy needs are met by biomass, but that could be greatly increased

8. Potential Energy Source?
In the United States, we already get 45 billion kilowatt-hours of electricity from biomass, about 1.2 percent of our nation's total electric sales
Estimates of the ultimate potential for biomass energy vary, depending on agricultural forecasts, waste reduction by industry, and paper recycling
The Department of Energy believes that we could produce four percent of our transportation fuels from biomass by 2010, and as much as 20 percent by 2030
For electricity, the U.S. Department of Energy (DOE) estimates that energy crops and crop residues alone could supply as much as much as 14 percent of our power needs.

10. DISAGREEMENTS
Biomass has a smaller energy content for its bulk than fossil fuels
Costs of labor, transportation, and storage would then be higher

11. ENVIRONMENTAL ADVANTAGES
Renewable resource
Reduces landfills
Protects clean water supplies
Reduces acid rain and smog
Reduces greenhouse gases
Carbon dioxide
Methane

12. BIOMASS AND CARBON EMMISIONS
Biomass emits carbon dioxide when it naturally decays and when it is used as an energy source
Living biomass in plants and trees absorbs carbon dioxide from the atmosphere through photosynthesis
Biomass causes a closed cycle with no net emissions of greenhouse gases

13. GEOGRAPHIC AREAS Comes from the forest
Can also come from plant and animal waste
Wood and waste can be found virtually anywhere
Transportation costs

14. ENHANCEMENT Wood is the largest resource
Expand by using other plants, residues, or waste
Finding different materials to use as fuel

15. DEVELOPMENT Many areas could be used
Potentially supply more than 20% of US energy supply
Bioenergy crops will be
More important in future
Come closer to area that
Need energy

16. TECHNICAL IMPEDIMENTS
Trees and other biomass is hard to gather
There is a low output of 34% energy gain
Development of cheapo and reliable combustion techniques that will not release pollutants

17. TECHNICAL IMPEDIMENTS
Development of gasification techniques that incorporate hydrogen to create syngas
Biomass contains less energy per pound than fossil fuels
Cost-inefficient to transport more than 50 miles before it is converted to fuel

18. SOLUTION The solution is to have decentralized processing plants
This means less transport of biomass
This is more cost-efficient
More reliable, regular, and better quality
Less competition between companies

19. ENVIRONMENTAL DISADVANTAGES
Crop and forest residues often contain high concentrations of important nutrients
If the residue is harvested as energy, the nutrients can be lost to the surrounding environment.
Other synthetic chemical nutrients or fertilizers can later be added
More plants and trees must be planted, because they will be used in a higher quantity

20. LAWS AND REGULATIONS
A number of federal laws and regulation apply to biomass energy deployment activities. For the most part, state laws and regulations do not apply to biomass energy development on tribal lands. Federal legal requirements apply to specific activities associated with biomass energy development.
The impacts of a specific project will be determined by factors such as the type and size of the biomass facility, the amount of land disturbed by construction activities, the amount of land in use by facilities long term, the location of the site with respect to other resources.

21. GOVERNMENTAL INITIATIVE
California produces more than 60 million bone dry tons of biomass each year. Of this total, five million bone dry tons is now burned to make electricity.
Many states promote biomass if cost, location and resources are to their benefit

22. SUSTAINIBILITY
Biomass is sustainable but there is an expense in producing and converting biomass into fuels and electricity.
Collecting biomass turned out to be very different than harvesting, as loggers gained more experience the process became much more efficient.
While biomass is one of the best forms of renewable energy, it is not a great fuel.

23. SUSTAINIBILITY
Removing too much biomass can use up nutrients from the soil and possibly increase erosion.
Biomass supplies about 15 times as much energy then solar and wind in the United States, and has the potential to supply much more.

24. CONCLUSION
Biomass is a potential alternative to fossil fuels but it is not very viable.
There are many problems in the development and transportation of it and carbon is a byproduct of processing of biomass, just like it is a byproduct of fossil fuels.
There are better alternative energies.
