Sustainable Development of Algal Biofuels The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal govern- ment on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its ad- ministration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also spon- sors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Charles M. Vest is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertain- ing to the health of the public. The Institute acts under the responsibility given to the National Acad- emy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to as- sociate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the Na- tional Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Charles M. Vest are chair and vice chair, respectively, of the National Research Council. www.national-academies.org Copyright © National Academy of Sciences. All rights reserved.

Sustainable Development of Algal Biofuels Preface T he desire to develop energy sources that can provide greater environmental and secu- rity benefits has spurred research and investments in the development of alternatives to petroleum, the dominant source of liquid transportation fuels. Because of its high biomass (and oil productivity in some cases), algae and cyanobacteria (commonly referred to as blue-green algae) frequently have been considered a promising renewable feedstock for fuel production. We all were taught that petroleum and other fossil fuels formed on this planet from plant remains that were compressed for millions of years at high temperatures. It seems fitting that scientists would choose to study some of the most primitive life forms to develop large-scale biofuel replacements for such fossil fuels. Algae have been grown under a variety of conditions for the production of lipids and high-value products for sev- eral decades. Two factors that influenced the consideration of algal biofuel production in the past were the cost of a barrel of oil and the ability to cultivate algae and process them into transportation fuel at a reasonable cost. The U.S. Department of Energy (DOE) had a robust program to develop biofuels from algae from 1978 to 1996, when it was concluded that algal biofuel would not be cost competitive with petroleum soon. Fast forward to 2012, and with advances in genetics and engineering, we are back to the future in considering whether algae can be an economic and sustainable alternative source of liquid transporta- tion fuels. Could it be that use of algae to produce biofuels is the answer to becoming less dependent on foreign oil? At the request of DOE, the National Research Council (NRC) appointed a committee of 15 experts with diverse backgrounds and experience to examine the sustainability of algal biofuels. The committee reviewed many scientific papers and government and industry reports, and listened first hand to company representatives, academic experts, and govern- ment agency program managers who deal with production of algal biofuels. The committee also met three times and held regularly scheduled conference calls to deliberate and reach agreement as to how to best address the charge from DOE to identify potential sustainability concerns, mitigate environmental concerns, and identify indicators of sustainability and metrics that could be used to monitor progress as the technology advances on several fronts. ix Copyright © National Academy of Sciences.
