Pascale Champagne: Research

Biomass to Bioenergy - AD Derived Biogas-to-SOFC

Project Descriptions:

This research is aimed at developing an innovative technology that optimizes municipal anaerobic digestion (AD) to effectively utilize a range of waste biomass substrates to generate biogas for use in solid oxide fuel cells (SOFC) in a combined AD-SOFC system. This project was undertaken in collaboration with Dr. Brant Peppley and Dr. Bruce Anderson from the Departments of Chemical Engineering and Civil Engineering at Queen's University, Dr. Christopher Thurgood from the Royal Military College and Dr. Hamid Salsali from the University of Guelph in the Spring of 2008 in collaboration with Utilities Kingston, BioProcess Solutions and Canadian Shield Energy Systems. It has been funded through an NSERC SPG and OCE Interact programs. The study will showcase a highly efficient heat and power cogeneration system that utilizes a greenhouse gas neutral, renewable biofuel, which could significantly reduce the cost of wastewater treatment operations, particularly in smaller communities. The study addresses the effects of an AD-derived biogas, which has some degree of variability in its composition, on fuel cell performance and investigates AD process optimization via waste biomass pretreatment and/or codigestion to minimize this variability. This work is coupled with the development of fuel conditioning strategies and flexible fuel cell control methodologies that will be adapted for this biogas fuel.

Feasibility of using of fats, oils and greases to augment biogas production at the City of Kingston Ravensview wastewater treatment facility. The bench-scale and pilot-scale testing project funded through an OCE Interact generated results that led to a series of recommendations for implementation at the full-scale facility. This experimental stage of this study was initiated in May 2007 in collaboration with Dr. Bruce Anderson in the Department of Civil Engineering at Queen's University, the City of Kingston and Utilities Kingston.
