Techno-economic and environmental assessment of staged oxy-co-firing of biomass-derived syngas and natural gas

•The co-firing of Biomass-based syngas and NG was considered.•The proposed cycle was shown to achieve a net efficiency of 42.6% and a net CO2 removal rate of 27 kgCO2/MWh.•The techno-economic performance of the proposed cycle is competitive to other power generation cycle.•The LCOE of the proposed c...
