N2 - This paper discusses a few promising physical and chemical technologies for the utilization and conversion of CO2 from a 500 MW coal-fired power plant into viable economic products. The main areas of interest were microalgae biomass production (pond and bioreactor production), supercritical CO 2 extraction technology, fixation of CO2 into organic compounds (production of various chemical products), and trireforming of CO 2 for synthesis gas production. The value added products that can be produced from these four main technologies are: biomass (high and low grade), biomassderived products (pharmaceutical, chemical or nutritional), synthesis gas, specialty products (extracted using supercritical technology), organic carbonates (linear, cyclic or polycarbonates), carboxylates (formic acid, oxalic acid, etc), salicylic acid and urea. The method employed for CO2 utilization depends on the desired products. It can be concluded, however, that chemical conversion and tri-reforming are the leading technologies when the aim is to sequester the most possible CO2. Despite the small percentages of CO2 being utilized by biological and scCO2 technologies when compared to the total amount emitted by a 500 MW power plant, the value-added products and yield are considerable.
