Evaluation of life cycle energy, economy and CO2 emissions for biomass chemical looping gasification to power generation

A life cycle energy use, CO 2 emissions and cost input evaluation of a 650 MW Biomass Chemical Looping Gasification Combined Cycle (BCLGCC) Biomass/Coal Integrated (BIGCC/CIGCC) power generation plants with without (w/o) capture & storage (CCS) are analysed. These were then compared to coal/biomass combustion technologies. The covers the whole process including biomass/coal supply chain, electricity at plant CCS process. showed lower emissions, yet higher costs plants. Coal illustrated input; however biomass can reduce near zero, while BCLGCC BIGCC resulted in negative 680 kg-CO /MWh 769 /MWh, respectively, which is due utilization efficiency for hence less captured stored. Regarding total (TLCCI), equal 149.3 £/MWh 199.6 £/MWh, (TLCEI) both 2162 MJ/MWh 1765 MJ/MWh, respectively.
