Description: Fossil fuel-based power plants contribute significant greenhouse gas (GHG) emissions. Displacement of fossil fuel-based power through biomass co-firing has been proposed as a near-term option to reduce the GHG emissions. In this study, biomass feedstock including wood chips, wheat straw and forest residue were co-fired with coal or natural gas on a 500 MW Subcritical Pulverized Coal (PC) plant. Several scenarios with various technologies were comparatively studied to determine their economic potential, costs and to provide insight into the environmental benefit each technology can offer. Preliminary results for the biomass-coal co-firing shows that minimum levelized cost of electricity (LCOE) ($41.77/MWh) and incremental cost of co-firing ($2.64/MWh) can be achieved with wheat straw at 10% co-firing level in a fully paid coal-plant while the highest LCOE ($128.45/MWh) and incremental cost of co-firing ($75.47/MWh) was achieved with wood chips at 75% co-firing level in a partially-paid coal plant. These results with the avoided CO2 cost for each scenario will be comparatively analysed with that of natural gas co-firing. A series of sensitivity analysis will also be conducted to determine the conditions under which each technology is most feasible and to guide experimental efforts toward the areas that could result in the largest costs and GHG emission reductions.
