L’approche économique des transitions énergétiques et l’innovation environnementale: une application au CCS et au BCCS
Journal Title: Revista Romana de Statistica - Year 2011, Vol 59, Issue 3
Abstract
Si les innovations environnementales vont être amenées à jouer un rôle décisif dans les transitions énergétiques, leur mise en ouvre n’a rien de spontané et nécessite de faire appel à des schémas incitatifs crédibles et des mesures réglementaires fortes. Les techniques en jeu sont en effet lourdes, engageant des externalités de réseau et des économies d’échelle, avec une forte incertitude technique et économique. Les techniques de capture et de stockage de carbone, à partir d’énergie fossile (CCS) ou de biomasse (BECCS) n’échappent pas à ces limites, auxquelles il faut ajouter celles pesant sur le prix du carbone évité, sur leur statut réglementaire, et leur acceptabilité. En tout état de cause l’intégration de ces techniques reste une priorité pour les systèmes nationaux d’innovation. Summary While the environmental innovations will play a key role in the transition towards new energetical systems, their implementation is rather difficult to be set up and will require some incentive and regulatory schemes. The techniques at stake are rather difficult to implement, implying scale and network économies, with an important technical and economic uncertainty. Carbon capture and Storage technique, from fossil fuels (CCS) or biomass (BCCS) are moreover submitted to the evolution of mitigation costs and of their acceptability. It is really a new challenge for the national Innovation system to help to develop these techniques.
