Prologue to the Future: UNC Climate Action Plan and Cogen n Climate Action Plan Published September 2009 n Two Cogen Projects over next 5 years: u Landfill Gas to Energy u Biomass Co-firing at Cogen
Cogen and UNC’s Climate Action Plan Near Term Impact
PROJECT BENEFITS n Reduction in greenhouse gas emissions n Methane destruction n The emissions reduction attributable to this project are equivalent to: n Removing the emissions of 7,860 automobiles or n Planting 9,750 acres of forest
PROJECT BENEFITS n Cost savings from avoided purchased power n Makes beneficial use of otherwise wasted gas n LFG project alone would make Carolina North carbon neutral for 12 to 15 years.
Biomass Cofiring in CFBs: Issues n Fuel Supply Chain and Cost n Front End Fuel Handling u Storage u Feed Systems n Impact on Combustion and Heat Transfer Surface n Baghouse Impacts n Ash Disposal Impacts n Amount of Carbon Reduction
Biomass Cofiring in CFBs: Plans n Test Protocols – March 2010 n Dried Wood Pellets Tests – Spring 2010 n Torrified Wood Tests – Fall to Winter 2010/2011 n Evaluation and Implementation Plan Development – 2010/2011 n Burn 2012 - ? (Fuel Supply Chain and Extent of Required Mods)
