The place of Bio-energy with carbon capture and storage in the future Energy-Climate regime: a long-term analysis with TIAM-FR

International audienceChallenges for energy and climate change involve evolution of the world energy system, especially of the technological mix permitting to satisfy the energy demands. Introducing an industrial scale of carbon capture and storage (CCS), and the combination of bio-energy, carbon capture and geologic storage (BECCS) appears more and more as incontrovertible in an increasing body of literature to reduce future GHG emissions in line with the consensual limit of 2°C temperature increase. BECCS is gaining increasing attention, as this alternative offers a unique opportunity for a net carbon removal from the atmosphere while fulfilling energy needs. The aim of this study is to analyze alternative development paths of the energy system investigating different constraints on the use of BECCS, under the climate policy context issued from the last Conference of Parties (COP 21 in Paris 2015) and the Paris Accord which will depict the future Energy-Climate regime. This analysis is conducted using the global multiregional TIAM-FR optimization model and implementing different pathways to achieve a low-carbon economy, in line with emissions targets expressed under the aegis of the UNFCCC climate negotiations and, according to several assumptions about the regional burden sharing
