(Lawrence Berkeley National Laboratory) A Realistic Technology and Engineering Assessment of Algae Biofuel Production

This report assesses the economics of microalgae biofuels production through an analysis of
five production scenarios. These scenarios, or cases, are based on technologies that currently
exist or are expected to become available in the near‐term, including raceway ponds for
microalgae cultivation, bioflocculation for algae harvesting, and hexane for extraction of algae
oil.  Process flow diagrams, facility site layouts, and estimates for the capital and operations
costs of each case were developed de novo.  This report also reviews current and developing
microalgae biofuel technologies for both oil and biogas production, provides an initial
assessment of the US and California resource potential for microalgae biofuels, and
recommends specific R&D efforts to advance the feasibility of large‐scale algae biofuel
