Adapting the Standard
What the RFS2 means for the industry.
Five years ago, renewable fuels took a step towards becoming the standard. A renewable fuels volume mandate, the first in the United States, was created. Known as the RFS (Renewable Fuel Standard), this mandate would see many changes over the next five years and accelerate ethanol production at an unprecedented rate.By Julie Flannery-Allen

THE BEGINNING
In 2005, a mandate was set to blend 7.5 billion gallons of renewable fuel into gasoline by 2012. It was the logical amount... at the time.
"The first RFS created market opportunities and financial certainty for a growing industry," adds Rob Skjonsberg, Senior Vice President of Public Policy & Corporate Affairs at POET.
Before the mandate, ethanol had a small primary niche market of adding oxygen to fuel with the purpose of cleaning up polluted cities.
"It was an important development as it set out a vision for ethanol to play out a bigger, broader role in our nation's efforts to reduce our dependence on foreign oil, benefit the environment and to create jobs in rural America, in fact the whole world," says Tom Buis, CEO of Growth Energy. "That challenge was easily met by the nation's ethanol producers."
RECOGNIZING A NEED
In December of 2007, the Environmental Independence and Security Act (EISA) revised and extended the RFS rule.
"EISA's changes were intended to provide a major step toward expanding the production of renewable fuels, reducing our dependence on oil, and confronting global climate change," explains Margo Oge, Director of the EPA's Office of Transportation and Air Quality. "One of the key changes in the Act was greatly expanding the RFS, requiring fuel producers to use at least 36 billion gallons of biofuel in 2022."
Another first, the EISA included competing mandates for advanced and cellulosic ethanol. Incentives were provided for the development of cellulosic commercialization, complementing POET's Project Liberty, a commercial scale cellulosic facility that will produce ethanol from corn cobs. But, RFS2 also capped corn ethanol production at 15 billion gallons.
Additional key changes in the Act included:
- EISA expanded the RFS program to include diesel, in addition to gasoline.
- EISA established new categories of renewable fuel, and set separate volume requirements for each one.
- EISA required EPA to apply lifecycle greenhouse gas performance threshold standards to ensure that each category of renewable fuel emits fewer greenhouse gases than the petroleum fuel it replaces.
REVISION NUMBER 2
On February 3, 2010, the U.S. Environmental Protection Agency (EPA) released its final rule for the expanded RFS.
Known as the RFS2, the rule took effect July 1, 2010, and lays the foundation for achieving significant reductions of greenhouse gas (GHG) emissions from the use of renewable fuels. All conventional biofuels must reduce GHGs by at least 20 percent in order to qualify for these new volume categories. (see sidebar "Fuel Categories," pg. 44)
The good news is that the final rule clarified that that corn grain ethanol meets this requirement and qualifies as a conventional biofuel. This includes all ethanol using corn as a feedstock, existing grandfathered capacity as well as new production.
This is to due to the EPA acknowledging some key points:
- Crop yields are continuing to improve, meaning less land is needed for increased ethanol production.
- Distillers grains are an efficient, high-nutrient animal feed, allowing the same corn to be used for both feed and fuel.
- Agriculture does not have the impact on deforestation that was originally assumed.
FLAWS
But Buis is concerned that it still "contains a couple of troubling barriers for this industry to move forward." Specifically a component called the International Indirect Land Use Change (ILUC) (see "Indirect & Inconclusive", Vital, Spring 2009). And an underwritten clause Skjonsberg has nicknamed the "discrimination clause" which prevents corn ethanol from competing with other feedstocks despite greenhouse gas reduction efforts.
INDIRECT LAND USE CHALLENGE
A relatively new topic of study, Harry Baumes, Acting Director of the Office of Energy and Policy New Uses Office of the Chief Economist, points out the importance of research in this area.
"Many factors affect land use change around the world including economic growth, economic development policies, population and technological developments," says Baumes. "We must be careful that we understand the complexities of market adjustments and that we are as confident as we can be in identifying and quantifying net GHG emission from indirect land use change brought about by biofuels production."
"The only way we can overcome these types of governmental challenges is if we move away from mandates and towards a fairer open market for fuel."
-Rob Skjonsberg, Senior VP of Public Policy & Corporate Affairs at POET
"There's been this debate about indirect land use change -- about what the impact is and how you really measure it," says Buis. "There's no scientific consensus out there that A, it's happening. And B, to what extent it's happening. Then if it is determined that it is...who do you blame for it? Land use changes in other countries occur for a variety of reasons. It's a lot of macro reasons such as domestic purposes for their own consumption or export for economic activity. It's not specifically for the production of biofuels or the result of the production of biofuels. In fact, we tell everyone that in the United States we lose about one or two acres per minute of tillable farmland to suburban sprawl."
But the U.S. farmers and ethanol producers do continue to be blamed for issues beyond their control -- like Brazilian deforestation.
Buis says, "In reality, in Brazil where they are most concerned about deforestation, over the last five years deforestation rates have been cut in half. At the same time, the U.S. ethanol industry nearly tripled its capacity, so there's no real connection there, between what we're doing here in the United States and what is occurring in Brazil."
The EPA rule mentions five categories of feedstock that are expected to result in less or no indirect land use change including:
- Crop residues such as corn stover, wheat straw, rice straw, citrus residues;
- Forest material including eligible forest thinning and solid residue remaining from forest product production;
- Secondary annual crops planted on existing crop land such as winter cover crops;
- Separated food and yard waste including biogenic waste from food; and
- Perennial grasses including switchgrass and miscanthus.
Currently, corn based ethanol falls into the conventional biofuels category with a 20 percent reduction of GHG, but without indirect land use change, the production of ethanol is approximately 52 percent less GHG omissions than gasoline.
So realistically, if this flawed theory were not considered, corn could be a feedstock used to fill the advanced biofuel space of the mandate by all other standards -- except for the discrimination clause.
DISCRIMINATION CLAUSE
In the definitions section of the RFS2, advanced biofuels is defined as "renewable fuel -- other than ethanol derived from corn starch." It goes on to list the types of fuels eligible for consideration: ethanol derived from cellulose, hemicelluloses, lignin, sugar or starch (other than corn starch), waste material, etc., etc., etc.
"The statute specifically prevents corn ethanol from participating in the 'advanced biofuel' category, regardless of the GHG reduction efforts," says Skjonsberg. "It's completely arbitrary and discriminatory."
With corn starch receiving unfair 42 vital || THE ESSENTIAL PERSPECTIVE
treatment, it gives other biofuels an
advantage.
"There's no carve out in the
RFS2 for corn based ethanol," says
Skjonsberg. "A host of competing
feedstocks -- including Brazilian
cane ethanol -- can actually displace
corn's participation in the first 15
bg portion of the RFS2."
It's a tough hand to be dealt.
With a government push towards
diversity in the way renewable
fuels are made, tried and true corn
ethanol gets the short end.
"The only way we can overcome
these types of governmental
challenges is if we move away from
mandates and towards a fairer,
open market for fuel," Skjonsberg
adds. "Ethanol can compete with
gasoline -- we simply need market
access and a movement away from
government caps and parameters.
This industry's potential has
outpaced the government. RFS2
made that very clear."
MEETING THE MANDATE
In an interview with ClearSkies
TV, Buis remarks, "Can we produce
it? Yes. In fact, it's going to take a
combination of efforts. It's going to
take efforts like corn based ethanol
and cellulosic ethanol. We are not
going to back off again. We know
we can do it, just make sure the
public policy corresponds to it¬--to
unleash the entrepreneurial spirit
in America."
In April, POET CEO Jeff Broin
announced POET's cellulosic
ethanol plan at the National Press
Club in Washington, D.C. The plan
sets a goal of 3.5 billion gallons of
cellulosic ethanol production by
2022.
POET plans to achieve this goal
"by adding the technology to our
existing facilities, licensing our
technology to other producers and
finally, transferring our technology
to other forms of biomass such
as wheat straw, switchgrass and
municipal waste," Broin said. "To
put this in perspective, 3.5 billion
gallons is over 20 percent of the
cellulosic ethanol mandated in the
Renewable Fuel Standard."
THE END RESULT
"The expanded use of renewable
fuels is expected to reduce
greenhouse gas emissions by 138
million metric tons when the
program is fully implemented
in 2022. The reductions would
be equivalent to taking about 27
million vehicles off the road,"
concludes Oge.
"From a consumer perspective,
increasing biofuels production and
use in the U.S. will create green
jobs and generate income and
economic gains associated with the
industry's development," Baumes
summarizes. "Increasing the supply
of home grown energy will help to
keep energy costs to the consumer
(and business) down -- for both
transportation fuels and heat/power.
In addition, renewable energy
provides environmental benefits
which all will benefit from."
In hard numbers, Oge explains
how the RFS2 will benefit the
American consumer. "The
increased use of renewable fuels
is expected to expand the market
for agricultural products such as
corn and soybeans and open new
markets for advanced biofuels. We
estimate that the RFS2 program
would increase net farm income by
$13 billion dollars in 2022."
She adds, "Further, by 2022, the
increased use of renewable fuels
is expected to decrease gasoline
costs by 2.4 cents per gallon and to
decrease diesel costs by 12.1 cents
per gallon."
Increased use of biofuels will
provide the solution our country is
looking for. The RFS2 will aid in
breaking oil's 90 percent monopoly
and give consumers the choice of
fuel.
"Even if you disagree on the
threat posed by climate change,
investing in clean energy jobs and
businesses is still the right thing to
do for our economy. Reducing our
dependence on foreign oil is still
the right thing to do for our security.
We can't afford to spin our wheels
while the rest of the world speeds
ahead," said U.S. President Barack
Obama to a group of governors in
early February.
FUEL CATEGORIES
The RFS2 provisions specify four separate categories of fuels, each with their own feedstock and minimum GHG reduction thresholds. Each category has its own annual volumetric use and a corresponding schedule for increases.

If advanced biofuel (50 percent GHG reduction) and cellulosic biofuel (60 percent GHG reduction) meet their volume, additional gallons produced in these categories will eat into what is allowed for corn-based ethanol (renewable biofuel - 20 percent GHG reduction).
BIOMASS-BASED DIESEL
1 billion gallons (bg) by 2012 and beyond; e.g., Biodiesel, "renewable diesel" if fats and oils are not co-processed with petroleum. Must meet a 50 percent lifecycle GHG reduction threshold relative to 2005 diesel baseline.
CELLULOSIC BIOFUEL
16 bg by 2022; renewable fuel produced from cellulose, hemicellulose, or lignin; e.g., cellulosic ethanol, biomass to liquids (BTL) diesel, green gasoline, etc.; Must meet a 60 percent lifecycle GHG reduction threshold.
ADVANCED BIOFUEL
Total of 21 bg by 2022 (Minimum of 4 bg additional); essentially anything but corn starch ethanol; Must meet a 50 percent lifecycle GHG reduction threshold reduction relative to 2005 baseline gasoline.
RENEWABLE BIOFUEL
Total of 36 bg by 2022 (Minimum of 15 bg additional); ethanol derived from corn starch -- or any other qualifying renewable fuel; Must meet a 20 percent lifecycle GHG reduction threshold -- Only applies to fuel produced in new facilities.
