Closing the TIMES integrated assessment model (TIAM-FR) raw materials gap with life-cycle inventories

Abstract : Energy system models ignore raw materials cycles and in-use material stocks. In this paper, we introduce a material accounting method as a first step towards addressing the raw materials gap in the TIMES Integrated Assessment Model (TIAM-FR version). The method consists in attributing life-cycle inventories (LCIs) taken from the Ecoinvent 3.3 database to the TIAM-FR technology processes constituting the world energy system. We start by disaggregating the LCIs into three separate life phases (construction, operation, and dismantling) and coupling them to their respective TIAM-FR process outputs (new capacities, operation, and retiring capacities) in order to estimate the annual raw materials requirements. We then demonstrate the method on the electricity generation sector in a baseline scenario on the 2010-2100 horizon. Prospective uses of fossil fuels and metallic and non-metallic mineral materials are quantified dynamically at the life phase level. The construction and dismantling of hydropower, solar and wind capacities generate increasing amounts of metallic and non-metallic raw materials in successive peak and valley periods. However, the total use of raw materials is largely driven by fossil fuels all along the horizon. Finally, we evaluate the sensitivity of global material use to variations in the technologies' dismantling phase. This novel approach can be extended to other energy system models and possibly other energy sectors.
