Increasing Popularity Fuel costs Renewable fuel CO2 neutral 2007 Annual Air Meeting
“CO2 Neutral” Can be up to 95% carbon closure even including costs for biomass production, transportation and plant construction. {DOE-NETL} CO2 Cycle 2007 Annual Air Meeting
What’s in Florida now? Currently, primary sources are: Sugar mills Pulp and paper mills Conventional power plants 2007 Annual Air Meeting
Sugar Mills “Bagasse” is fibrous, vegetative residue that remains after milling sugarcane and extracting sugar. Currently, 6 sugar mills in Florida Traditional boilers Process steam Small amounts of electricity Bagasse is: “Free” Renewable Carbon neutral 2007 Annual Air Meeting
Pulp and Paper Mills Combustion units: • Combination boilers • Power boilers • Recovery boilers • Process steam • Moderate amounts of electricity Bark, wood, BLS and RLS: • “Free” • Renewable • Carbon neutral Florida has 5 sulfate process mills and one sulfite process mill. These mills digest wood to make paper and specialty fibers. 2007 Annual Air Meeting
Example (TECO) … preserve our environment for future generations by using renewable energy sources like biomass (plant materials), sunlight and landfill gas to generate electricity. Conventional Power Plants Each 200 kilowatt-hour block subscribed to will offset over 5,600 pounds of carbon dioxide (CO2). A “block” of renewable energy equals 200 kilowatt-hours (200kWh) of electricity on the electric grid. And it only costs you $5 per month, conveniently added to your electric bill. Over 1-year period, offsets same CO2 emissions as: 1 block = not driving an average car for 6 months 3 blocks = planting two acres of trees 4 blocks = removing two average cars 2007 Annual Air Meeting

E-Grass A perennial member of the grass family, like bamboo or sugar cane. Produces a high yield and can be harvested up to twice annually. • At maturity, > 100,000 stalks per acre of land • Extremely hardy with no natural enemies • Grows in poor soils without fertilizer and little rainfall • Flourishes in warm climates, fast growing • Stalks have natural wax that repels moisture and • protects chips from deteriorating during storage • Used as ornamental throughout southern U.S. • Requires less water due to its deep roots 2007 Annual Air Meeting
