Abstract

The objective of the present work is the study of the optimal possibilities for a future implantation of Bio-Energy with Carbon Capture and Storage (BECCS) and the comparative analysis of the most promising ones. The selection process of the optimal alternatives was based on existing studies. Principally, the proposed results by TESBiC were followed. This study starts from a selection of 28 possible viable technologies for the use of biomass and CCS, and an exhaustive comparison between 8 of them. Finally, Chemical Looping and Carbonate Looping were chosen for further research. To provide the reader with a global vision of the processes, which allows a correct evaluation of the same and in order to maintain at all times an assessment of the negative CO2 emissions, three parameters are analyzed by comparision of this technologies with a coal reference power plant without CCS. From a technological point of view it is important to know how efficient the processes are, and specifically in this case, what capture capacity exists. For this, the CO2 capture efficiency is analyzed through the investigation of the most recent investigations. In an environmental level, the fulfillment of the 2ºC target implies that global CO2 emissions will have to be reduced to zero or even need to become negative in the future, due to this the Emissions Factor is analyzed in order to give a vision of the potential reduction of emissions. Finally, it is essential to take into account the economic viability of these technologies if their future implementation is intended, for which the Levelized Cost of Electricity is calculated. However, for an evaluation of the options that are really worthwhile and advisable, only the relationship between CO2 emissions and electricity generation costs can really estimate the potential. Due to this, the avoidance cost will also be studied. For the results, the creation of a range of uncertainty was necessary to cover the variation of data found in the literature. The emissions obtained for Chemical Looping are in the range of -849.11 / -777.93 [kg/MWhe] at a cost between 132.51 / 82.37 [€ / MWhe]. For co-fire Carbonate Looping the emissions have reached ranges of -592.19 [kg / MWhe] for costs of 99,67 [€ / MWhe]. In general, the avoidance costs obtained for Chemical Looping are lower, although the range of uncertainty is higher, and this technology has a high suitability for small plant scale. For Carbonate Looping, the possibilities of mixing fuel are much greater due to the presence of two reactors, and a worth possibility of this process is the possibility of use existing coal plants, since it is a plant that is additionally integrated to the existing one.
