Is Iowa ready to lead the era of cellulosic energy?
By BRUCE BABCOCK, ROBERT BROWN
and GREGORY GEOFFROY
Iowa has made tremendous strides in developing its ethanol industry, and we
are, without question, the nation's leader in production of grain ethanol from corn.
But we have taken only the first step in achieving our shared vision of Iowa
sustaining its leadership in the emerging bioeconomy.
If we are to continue our leadership role, we must focus more on the long term
than our present good fortune. Specifically, we must begin thinking about the
"next phase" of biorenewable fuels. Most experts believe the next phase will be
the generation of "cellulosic ethanol" and other biofuels from abundant
lignocellulosic plant material. These experts believe this next phase is not far
away, with the first commercial plant producing cellulosic ethanol as early as
2010.
Lignocellulose is the structural material of the plant world, more commonly known
as plant fiber. It is the major constituent of most crop residues, such as
cornstalks, wood and grasses. Although it is much more difficult than corn grain
to break down into sugars from which ethanol and other products are produced,
the potential supply from agriculture is many times larger than that of corn grain.
Experts agree that the costs of growing enough corn to meet all of our needs for
food and feed and to supply more than about 8 percent of future demand for
transportation fuels will be high. To make a significantly greater dent in our
dependence on foreign oil, we must look to sources such as lignocellulose. We
need to address both the technical and policy issues that will make this prospect
a reality in Iowa and the United States.
Scientists and engineers have been investigating the technical challenges of
cellulosic ethanol for more than 30 years, but research is just now beginning to
emerge from the laboratory into pilot-scale tests and demonstration plants. Many
states are beginning to position themselves to be the technology leaders and
manufacturing centers for cellulosic ethanol, and it is dangerous for Iowa to
assume that just because it has emerged as the leading producer of grain
ethanol, it will also become the capital of cellulosic ethanol.
As the leading corn producer in the United States, it was reasonable to expect
the grain-ethanol industry to locate here to be close to its resource base.
However, lignocellulosic energy crops are not currently part of the mainstream of
American agriculture, and virtually any state with significant agricultural or
forestry resources can compete in this emerging industry. This time, Iowa will
have to create its competitive advantages in advanced renewable fuels.
The time is now for Iowa's leaders to start formulating policies and programs to
ensure that Iowa continues its leadership into the era of advanced renewable
fuels prepared from lignocellulosic energy crops. Some of the critical topics that
must be addressed include:
- Policies and incentives that encourage investment in cellulosic ethanol and
other renewable fuels in Iowa, including greater use and availability of E-85
blends (85 percent ethanol).
- Support for expanded research into renewable-fuels production from
lignocellulosic materials and research into the viability in Iowa of high-yield
biomass crops, like miscanthus, along with an analysis of how farm programs
affect that viability.
- Support for the infrastructure investments that will be essential to enable Iowa
to continue to be the low-cost provider of biofuels.
- A variety of conservation and environmental issues to ensure that Iowa's
environment and resource base are not degraded from increased biofuels
production.
- The impact of the biofuels industry on Iowa's traditional agricultural base.
To help formulate those policies and programs, we will convene a meeting Nov.
28 at Iowa State University for biorenewables technology and policy experts from
industry and academia, members of the Iowa Legislature, and representatives of
state and federal government agencies and other key Iowa groups to generate
specific recommendations for Iowa's leaders.
There is urgency to act, since other states are moving decisively to encourage
the growth of the advanced renewable-fuels industry within their borders. It is
imperative that we not let others assume the lead and as a result garner the
benefits that Iowa now enjoys.
BRUCE A. BABCOCK is director of ISU's Center for Agricultural and Rural
Development; ROBERT C. BROWN is director of ISU's Office of
Biorenewables Programs; and GREGORY L. GEOFFROY is president of
Iowa State University.
Attend the meeting
Iowa State University will convene a meeting on Tuesday, Nov. 28, to discuss
emerging policy issues related to the development of the biofuels industry in
Iowa.
The meeting will begin at 8 a.m. at the Scheman Continuing Education Building
on the ISU campus and will feature technology and policy experts from industry,
academia and government and representatives from other interested
organizations.
For more information, contact John Anderson, Office of the President, ISU, (515)
294-2042, jrander@iastate.edu.
The meeting is open to the public.
