Integrating biomass with this technology holds promise for reducing fossil fuel consumption and achieving negative carbon emissions.

This study used ASPEN Plus to analyze the performance of a 550 MW staged, pressurized oxy-biomass combustion power plant. The results indicate that air separation unit (ASU) is the main energy consumption unit.

This improvement is mainly due to the higher moisture in Bio-SPOC flue gas, allowing for more latent heat recovery.
