Implications of CO₂ Sourcing on the Life-Cycle Greenhouse Gas Emissions and Costs of Algae Biofuels.

ABSTRACT: Production of algal biomass and its conversion to biofuels are important technological platforms within the larger umbrella of CO₂ capture and utilization. This analysis incorporates a life-cycle assessment (LCA) with respect to global warming potential and techno-economic assessment (TEA) of algae biofuels, focusing on the sourcing and delivery of CO₂. This analysis evolves past work in this area to include high-purity biogenic CO₂, industrial fossil fuel use, fossil power plants, and direct air capture, and uses a Sherwood plot approach to estimate the CO₂ capture energy penalty. We also show that allocation or displacement facilitates a more intuitive distinction between biogenic and fossil sources of carbon. Thus, the LCA better reflects the
