Transcript of Biomass

What's it made of? How It's Made Primary Uses What are the environmental impacts of biomass energy? How is Biomass Energy Efficient? Wood
Alcohol Fuels
Landfill Gases Biomass! Victoria Banos

Mariana Rico We use those to create a clean, renewable source of energy. A Helpful Visual Aid The Carbon Cycle shows exactly how biomass is created. AS you can see, it is a relatively simple and clean process. Adoption Rates Questions? Dump trucks gather waste materials
and bring them to a biomass power plant. The waste is burned which creates heat.
The heat builds up and pressure increases.
The pressure pushes giant turbines and
generates electricity. Pipelines are put into landfills where gas is burned.
The resulting methane gas is collected and is used as energy in power plants. Method 1: Method 2: Thanks for watching! WELL... Since biomass energy can be used for producing electricity and heat, it needs to be utilized in the best way possible. The actual efficiency depends heavily on the source of the biomass and the method of extracting the energy that is being used!
For example ... ... ... ... Example:
Burning wood can create electricity and heat to power a whole city, however, doing so would cause deforestation, erosion, and air pollution from the smoke released into the atmosphere. Biomass is renewable, unlike the fossil fuels such as oil, which is projected to run out entirely within the next 100 years. Biomass also burns much cleaner than fossil fuels do. The problem with biofuel is that making it, destroys trees and plants which leads deforestation and erosion. BIOMASS IS GREAT! ... KIND OF... MARIANA WAS HERE 10% of the World's energy comes from Biomass. 33% of the World's energy comes from Oil.
In the United States, biomass consumption is as low as 3%, whereas oil consumption is 39%!! 1. 2. 3. 4. 5. Direct combustion-
The burning of dry organic matter, such as wood scraps and grass. Chemical conversion-
Soybean and canola oils can be chemically converted into liquid fuel known as biodiesel. These fuels can be used as gasoline in conventional engines with little modification to the system. Ohio is the nation's fifth largest producer of soybeans ("Biomass Energy Program and Current Projects") Pyrolysis-
The heating of organic compounds to produce different gases, such as methane, carbon monoxide, or hydrogen. Anaerobic digestion-
The creation of methane by certain organic compounds, specifically municipal biosolids (sewage) and animal wastes (manures). Fermentation-
The creation of ethanol by fermenting and distilling sugar solutions, such as those processed from cellulose or carbohydrates. Trees and grasses are sources of cellulos whereas corn is a source of carbohydrates. Trees and grasses grown as an energy crop yield 4-5 times more energy than they take to grow, and corn as an energy crop yields 34% more energy than it requires in production Sydney Was here :)
