Environmental protection and specifically Climate Change, has been become a global problem not only of social responsibility but also an obstacle for economic growth and development. The 5th Assessment Report of the International Panel on Climate Change (IPCC) and the 2015 Paris Agreement conclude it is needed to reduce the Greenhouse Gasses (GHG) emissions and even to develop carbon Negative Emission Technologies (NETs) to limit the global average temperature increase to 2 ºC during the present century. The energy sector is considered as one of the major contributors to anthropogenic CO2 emissions. Capture and Storage (CCS) technologies are an interesting technological option to reduce CO2 emissions from these punctual large emitters. The combination of CCS technologies with thefact that CO2 emissions from biomass combustion are considered neutral opens the possibility to Bio-Energy with Carbon Capture and Storage (BECCS), a recently proposed alternative among NETs. BECCS development wouldcontribute to achieve Paris Agreement objectives on atmospheric GHG concentrations. Chemical Looping Combustion (CLC) has been studied during the last decades as a promising capture technology due to the low cost of CO2 capture and its low energy penaltyassociated [1]. This technology allows the combustion in a N2-free atmosphere. The oxygen is transferred to the fuel by a solid Oxygen Carrier (OC) circulating between two fluidized bed reactors. In the fuel reactor the fuel is oxidized and an almost pure CO2 stream generated. In the air reactor, the oxygen carrier is regenerated in air. The objective of this work is to analyze the feasibility of the CLC with biomass as a BECCS technology. For that purpose, three biomass residues (pine sawdust, olive stone and almond shell) were evaluated between 900-1000ºC in a continuous 500 Wth unit operating under In situ Gasification-Chemical Looping Combustion (iG-CLC) mode at Instituto de Carboquímica (ICB-CSIC, Spain) withlow-cost oxygen carriers.
