THE PLACE OF BIOENERGY CARBON CAPTURE AND STORAGE IN THE FUTURE ENERGY-CLIMATE REGIME: A LONG-TERM ANALYSIS WITH TIAM-FR

摘要

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