The position of bioenergy in a low-carbon world: Prospective analysis and biomass chain development in TIAM-FR model

With growing concerns about the environment, countries are increasing efforts to reduce their fossil fuel dependency, the major source of greenhouse gas emissions, by replacing them with clean energy sources including bioenergy. In this context induced by the Paris' Agreement and climate change mitigation targets, the bioenergy is being highlighted in the pathway to the decarbonization of our society. The work of this thesis concentrates on the perspectives of bioenergy development aiming to analyze the evolution of bioenergy production in view of policies, global exchange of biomass resources and the sustainable utilization of bioenergy in the long term in a context of decarbonization of societies. In terms of analysis, this thesis focuses also on the better implementation of bioenergy chain in our global energy system optimization model, TIAM-FR. This manuscript is structured in four chapters. The first chapter presents the actual position of bioenergy, bioenergy development strategy as well as the way how they are integrated into our modeling approach. The second chapter is dedicated to present the developments effectuated for the bioenergy chain in the model TIAM-FR. The third chapter shows our work regarding the evaluation of biomass resources potentials. Lastly, the role of bioenergy in the climate change mitigation context has been discussed at a global scale and by a focus on four Asian countries, China, India, Japan and South Korea. (author)
