Résumé:	La biomasse et le stockage géologique du carbone (CCS) sont deux méthodes ayant un grand potentiel dans la réduction des émissions de CO2. Leur bilan carbone respectif tend vers la neutralité et évite une contribution à l'augmentation du CO2 dans l'atmosphère. En revanche, le couplage de ces deux techniques conduit à pomper activement le carbone de l'atmosphère et engendrer des bilans négatifs. De plus, la spécificté des gaz de biomasse capturés ouvre des perspectives sur de nouveaux moyens de sécurisation des sites de stockage.
