High Efficiency Renewable Energy From Residual Materials

Recent price increases for various forms of energy along with projected shortages of supply have resulted in renewed interest in alternative fuels. Biomass gasification provides a renewable basis for supplying electric power and also a broad suite of chemicals such as Fisher-Tropsch liquids as well as hydrogen. The Taylor gasification process, being developed by Taylor Biomass Energy is a biomass gasification process that produces a medium calorific value (MCV) gas. The Taylor gasification process provides improvements over currently available gasification processes by integrating improvements to reduce issues with ash agglomeration and provide in-situ destruction of condensable hydrocarbons (tars), an essential element in gas cleanup. The gas conditioning step integrated into the Taylor Gasification Process provides a unique method to convert the tars into additional synthesis gas and to adjust the composition of the synthesis gas. Taylor Biomass Energy has developed and refined a sorting and recycling process that can produce a clean feedstock for energy recovery from abundant residue materials such as construction and demolition residuals and municipal solid wastes (MSW). The sorting and separating process can then be coupled to the Taylor gasification process to produce clean, sustainable energy. The development process including integration with a gas turbine based combined cycle system, connection into the New York ISO, and identification of renewable energy credit options is discussed along with a discussion of the Taylor Gasification Process, its modular design, and implementation into the commercial Biomass Integrated Gasification Combined Cycle (BIGCC) system in Montgomery, NY.
