This work was presented at the TechConnect Conference in Boston, MA on June 17, 2019. NETL is evaluating the environmental life cycle impacts of algae biofuels synthesized using CO2 from five types of thermoelectric power plants. The power plants considered in the analysis are (1) Subcritical Pulverized Coal-fired Power Plant (SubPC), (2) Supercritical Pulverized Coal-fired Power (SCPC), (3) Solid Oxide Fuel Cell Power Plant (SOFC), (4) Oxycombustion Pulverized Coal Plant (OxyPC), and (5) NGCC to model algae biofuel pathways. Both flue gas and captured (amine-based solvent) CO2 scenarios are considered. Algae-to-biofuel conversion is modeled via Combined Algae Processing (CAP) and Hydrothermal Liquefaction (HTL) pathways with the algae cultivation in open raceway ponds (ORPs) and photobioreactors (PBRs).
