From geology to economics: Technico-economic feasibility of a biofuel-CCS system

Abstract : This paper presents a method to estimate the technical and economic feasibility of capturing and geologically storing CO 2 resulting from biomass fermentation. The methodology is applied to the case of bio-refineries in the Paris Basin, France. The first step is to build a 3D geological model of the area studied and to choose the optimal injection location from geological and environmental constraints. Then, based on this information, the design of the CCS system (pipeline length, number and type of wellbores, surface equipment ...) and the estimation of the technical feasibility (sufficient storage capacity, risk analysis and management ...) can be performed. The last step is the estimation of the environmental benefits of this system (through a carbon and energy footprint) and its economic long term feasibility thanks to a discounted cash flow analysis. The impact of geological constraints on the economic feasibility of the system is estimated through a sensitivity assessment on the number of required injection wellbores
