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
