Biomass Fuel

If you have a fireplace, the wood you burn in it is a Biomass fuel. What we now call a Biomass fuel was the source of heating for thousands of years.


Biomass a general description
Biomass: A General Description

  • Biomass is energy that comes from organic material like plants

  • Plants use photosynthesis to grow(Sunlight and Carbon Dioxide), the energy from the plants is then used to produce(Ethanol, Methane, Bio Diesel or Heat).

Methane

Ethanol

Bio Diesel


Examples of biomass
Examples of Biomass

  • Biomass fuels include: wood, wood waste, straw, manure, sugar cane, switch grass and other organic material


Biomass energy conversions
Biomass Energy Conversions

Direct Combustion- burning of biomass to produce heat for space heating and electricity production.

Biochemical (Bio Fuel)- the decomposition of organic material to produce ethanol, methane, or bio-diesel

Direct Combustion

Biochemical

(Bio Fuel)


Biomass current technologies
Biomass: Current Technologies

  • Ethanol is created and blended with Gasoline

  • Bio-Diesel is a the reuse of restaurant cooking oils and blended with Diesel


Why is biomass so good
Why is Biomass SO good?

Carbon cycle: the process by which carbon is taken up by plants and animals and returned to the environment in a continuous cycle


Biomass future development
Biomass:Future Development

  • Improved processing to utilize (hemi)cellulose

  • Continue process improvements in cogeneration techniques with coal burning power plants

  • “Gas stations” must also service biofuels

  • Car manufacturers must continue to modify the internal combustion engine to appropriately utilize biofuels.

  • New fuels need to be competitively priced
