Transcript of Biomass energry
Enviromental Benefits-Biomass fuels produce virtually no sulfur emissions, and help mitigate acid rain.
Biomass fuels "recycle" atmospheric carbon, minimizing global warming impacts since zero "net" carbon dioxide is emitted during biomass combustion, i.e. the amount of carbon dioxide emitted is equal to the amount absorbed from the atmosphere during the biomass growth phase.
The recycling of biomass wastes mitigates the need to create new landfills and extends the life of existing landfills.
Biomass combustion produces less ash than coal, and reduces ash disposal costs and landfill space requirements. The biomass ash can also be used as a soil amendment in farm land.
Perennial energy crops (grasses and trees) have distinctly lower environmental impacts than conventional farm crops. Energy crops require less fertilization and herbicides and provide greater vegetative cover throughout the year, providing protection against soil erosion and watershed quality deterioration, as well as improved wildlife cover.
Landfill gas-to-energy projects turn methane emissions from landfills into useful energy.
Negative Effects-it actually creates more cabron in the atmosphere and it is the conversion of organic material into a source of heat. Namely fire. It actually creates more cabron in the atmosphere and it is the conversion of organic material into a source of heat. Namely fire.
Estimated cost of generating electricity from a new natural gas-fired, combined-cycle power plant is 2.8 cents per kilowatt-hour.
Estimated cost is 2.9 to 3.6 cents per kilowatt-hour
A plug-flow digester designed to process the manure of 500 dairy cows will have capital costs in the range of $230,000 to $260,000. Electricity and heat generated from digester gas reduce farm energy costs. Liquid and fiber digester residues have value as fertilizers and soil amendments. The costs of building and operating the digester can be recovered from sales of these products and from energy cost savings.
A blended fuel of 20-percent biodiesel and 80-percent petroleum diesel could reduce the production cost to about $1.10 per gallon, assuming a petroleum diesel cost of 90 cents per gallon and a soybean biodiesel cost of $1.80. Use of lower-cost organic oil feedstock, such as waste food-processing oil or tallow, would further reduce the production cost of biodiesel and biodiesel-blended fuel.
estimated production cost using these feedstocks is $1.15 to $1.43 per gallon
estimated cost of producing biodiesel is $2.56 per gallon of rapeseed methyl ester. Recent estimates put the cost of production in the range of $1.30 per gallon (using waste grease feedstock) to $2.00 or more per gallon using soybean oil.
