Modeling and Evaluation of Bioenergy and Agriculture System Integration

This Ph.D thesis focuses on exploring the integration between agriculture and bioenergy, by developing and analysing biomass fuelled energy system concepts that can produce heat and power in the effort of replacing fossil fuelled production. Bioenergy technologies based on thermochemical and biochemical conversion have been developed to utilize residual resources from agricultural systems. Nevertheless, these technologies are more often used in systems that maximize energy generation while disregarding and destroying the "waste" products which often contain essential elements to agriculture. Those type of systems could then eventually lead to soil depletion and contribute to mineral resource scarcity. New energy system concepts are developed in this thesis that 1) maximize biomass utilization for heat and power generation 2) while maintaining soil quality and 3) decrease consumption of mineral fertilizers in the agricultural system.
