Abstract:
Six thesis chapters were developed; Chapter 1 provides background information and possible scenarios for polygeneration systems—specifically, the integration of biomass gasification and renewable-energies-driven water electrolysis for hydrogen-rich syngas production. Chapter 2 provides a review study of the integration of heat pumps into DHC (District Heating and Cooling) networks and how it be an innovative and profitable solution for different decarbonizing sectors. Chapter 3 developed a rigorous but straightforward gasification model for designing and simulating a biomass gasification plant using the equation solver program Engineering Equation Solver (EES). Chapter 4 included an experimental investigation of the steam gasification of palm kernel shells (PKS) for hydrogen-rich N_2- free syngas production in a pilot-scale atmospheric downdraft allothermal gasifier. Chapter 5 included the design and thermal characterization of an alkaline electrolysis cell for hydrogen generation at atmospheric pressure. Finally, in the last chapter, all previously developed models and experimental data are integrated to analyze polygeneration systems in low-temperature district heating and cooling networks in Lachine Est in Montreal, Canada.
