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 government 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 administration 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 sponsors 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 pertaining to the health of the public. The Institute acts
under the responsibility given to the National Academy 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 associate 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 National 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.

Sustainable Development of Algal Biofuels

Preface

The desire to develop energy sources that can provide greater environmental and security
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 several decades. Two factors that influenced the
consideration of algal biofuel production in the past were the costs 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 transportation 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 government 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.
