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 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

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


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

  • 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?

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

  • 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
