Microalgae cofiring in coal power plants: Innovative system layout and energy analysis

摘要

This paper investigates the smart integration of a 500 ha microalgae culturing facility with a large scale coal power plant (758.6 MWe): a fraction of the CO2 contained in the coal plant flue gases is used for the algal cultivation, a fraction of the low-temperature flue gas heat available is used for the biomass drying, finally the produced biomass is co-fired in the coal plant. The produced algal biomass represents approximately 1% of the boiler heat input.
