The National Algal Biofuels Technology Roadmap Workshop, held December 9-10, 2008, was convened by the U.S. Department of Energy's Office of Biomass Program in the Office of Energy Efficiency and Renewable Energy (EERE). The primary purpose of the workshop was to discuss and identify the critical barriers currently preventing the economical production of algal biofuels at a commercial scale. The workshop addressed topics and technical barriers such as: algal biology, feedstock cultivation, harvest and dewatering, extraction and fractionation of microalgae, algal biofuel conversion technologies, co–products, etc. This document is intended to provide a comprehensive roadmap report that summarizes the state of algae-to-fuels technology and documents the techno-economic challenges that likely must be met before algal biofuel can be produced commercially. Taking these barriers into consideration, this roadmap also serves to make research and funding recommendations that will begin to lay the groundwork for overcoming the technical barriers that currently prevent the production of economically viable algal-based biofuels.
