Biodiesel Overview
Wendy ClarkNational Renewable Energy LaboratoryGolden, Colorado
What is biodiesel?
• Mono-alkyl esters of fatty acids (i.e. methyl or ethyl esters)
• Must meet the quality requirements of ASTM D6751• Typically used as blend with petrodiesel (up to 20%)• $1/gal tax credit for agri-biodiesel (vegetable oil/animal fat), $0.5/gal for
waste cooking oil – initiated in January 2005
100 lb triglyceride + 10 lb alcohol = 10 lb glycerine (byproduct) + 100 lb Mono-alkyl estersoy oil methanol Biodiesel

How is Biodiesel being used in the USA?
• As a blending stock with petrodiesel (B20)– Federal, state, and alternative fuel provider fleets– EPAct and Executive Order Compliance– School Buses– Emissions Reductions
• In low levels with petrodiesel (B2)– Lubricity and Ultra Low Sulfur Diesel Fuel– Agriculture supporting its own product
• Very limited B100 Use

Biodiesel is truly renewable
Petroleum diesel uses 1.2 MJ of fossil energy to produce 1 MJ of fuel product energy.
Fossil energy ratio = 0.83
Biodiesel uses 0.31 MJ of fossil energy to produce 1 MJ of fuel product energy
B100 Fossil energy ratio = 3.2
B20 reduces life cycle petroleum consumption by 19%B20 reduces life cycle CO2 emissions by 16%

Biodiesel Production Process –Crude Products
Fat or Vegetable Oil
Excess Methanol
Catalyst(caustic soda, NaOH)
Crude Biodiesel for Purification
Crude Glycerol for Sale or Purification
Methanol for Purification and
Recycle
Potential Impurities in Biodiesel• Methanol
– Degrades some plastics and elastomers, corrosive– Can lower flashpoint to unsafe levels (fire safety)
• Unconverted/partly converted fat (bound glycerin)– Results in very poor cold flow properties, injector and
in-cylinder deposits, potential engine failure
• Glycerin (free glycerin)– Results in injector deposits, clogged fuel filters, deposit
at bottom of fuel storage tank
• Catalyst– Excessive injector, fuel pump, piston, and ring wear,
filter plugging, issues with lubricant
ASTM D6751-06e Limits Impurities
• Flashpoint 130ºC minimum – Limits methanol to very low level
• Total glycerin is limited to 0.24 wt% maximum
• Free glycerin is limited to 0.02wt% maximum
• Sodium + Potassium limited to 5 ppm max and sulfated ash is limited to 0.020 wt%– Limits catalyst and other impurities
• It is critical to insure that all B100 meets D6751 limits
4
Biodiesel Degradation• Biodiesel can degrade in storage:• Oxidation
– Increases acidity (limited in D6751-06e to 0.5)– Forms gums– A stability requirement will likely be added to D6751
• Microbial contamination– Biodiesel is biodegradable– Microbes form films or mats that can plug filters– Requires water in storage tank– Storage tank housekeeping issue/biocide treatment– Also an issue for petroleum fuels
ASTM Specification For Blends
•Engine manufacturer’s top priority
•Need ASTM specifications for biodiesel blends
•Do not exist today
•Critical for protection of engines from poor quality fuel
•A necessary requirement is an oxidation stability specification for B100
•These issues are preventing engine manufacturer’s from offering warranty coverage – thus a significant market barrier
Can B100 Stability Ensure B20 Stability?
Yes, B100 stability appears to be an excellent predictor of blend stability, 3 hour Rancimat ensures low deposits and 6 hr Rancimat in the blend

Stability Study Conclusions
• Similar data available for 5% biodiesel blends• Blend stability is dominated by B100 stability• A 3 hr Rancimat IP for B100 appears to be
adequate to ensure stability of both B5 and B20 blends
Emission Benefits of B20
• Broad agreement on reductions on PM and toxics– 10 to 20% reduction in PM, depending on engine, test
cycle, and other factors– Aggregated toxics ~5% lower
• Impact on NOx emissions is uncertain– But EPA analysis of published data found B20 causing
NOx to go up ~2%– Based on engine testing– Several states have considered outlawing biodiesel
because of this• California and Texas in particular
NREL Vehicle Testing Summary
• Average change in NOx for B20 use is -0.6% – not statistically significant
• Magnitude and direction of NOx impact is cycle dependent

Fleet Evaluation Summary
• Also examining:– Fuel filter plugging issues– Fuel quality– Lube oil degradation– Emissions
• Need to couple with engine dynamometer durability• To have major impact need to complete 5 or 6 similar
studies
Closing Remarks• Biodiesel is a significant sustainable energy resource for the United States• Poor understanding of oxidation stability is limiting development of ASTM specifications for blends
– initial results shows that ensuring B100 stability will ensure the stability of blends
– additional research is required to relate fuel stability to engine durability
• There are not sufficient data to say if B20 blends cause NOx, on average, to go up or down
• Indications are that as little as 5% biodiesel increases the reactivity of PM in a DPF
• Interim results show no difference in operating costs or engine wear for use of petrodiesel versus B20
– much more in-use data is required to fully understand B20 impacts• Major research need is testing of biodiesel in post-2006 engines

Slide 1
Introduction/Overview
I appreciate the opportunity to participate in this years Congress and on this panel. My job
today is to discuss a broad range of E-85 topics.
Interest in E-85 has grown dramatically in the past two years. There are a number of factors that have
lead to this increased interest.
E-85 and the Fleet OperatorPresented by Robert E. Reynolds, Downstream Alternatives Inc.

Slide 2
The 2005 Energy Policy Act contained a requirement to use 7.5 billion gallons per year of
renewable fuels. President Bush touted ethanol and biofuels in his State of the Union Address and his
administration advocates the production and use of 60 billion gallons of ethanol by 2030. These ac-
tions are in recognition of rapidly increasing oil prices that result from world politics, unstable supply
sources and increasing world oil demand. And it is now significantly cheaper to produce a gallon of
ethanol than a gallon of gasoline.
Ethanol, used predominantly in E10, has expanded dramatically and ethanol production has
increased in response.

Slide 3
This slide shows the ethanol plant population as of April 2005. Actually a map of April 2006
would be even more impressive. In April there were 101 active plants at 4.56 billion gallons per year
capacity. There were 36 plants under construction with a total capacity of 1.86 billion gallons per year
and there were also 9 plants undergoing expansion. Another 111 proposed projects with at least 50 of
these likely to be built represent another 4 billion gallons annual capacity. So ethanol is a hot topic, its
use is increasing and new plants are being built. But the lofty ethanol volumes envisioned by the
current administration can only be reached using E-85 in flexible fuel vehicles (FFV).
The automakers, especially GM and Ford, have initiated programs to increase demand for E-85
and their flex fuel product line-up.
E-85 and the Fleet OperatorPresented by Robert E. Reynolds, Downstream Alternatives Inc.

Slide 4
The highest profile program is probably GM’s “Live Green Go Yellow Program” but Ford is
also actively promoting E-85. There are now over 5 million FFV’s in use with hundreds of thousands
being added each year. The product line of vehicles continues to expand.
These slides cover recent and current product offerings listed on the National Ethanol Vehicle
Coalitions website: www.e85fuel.com. As you can see the product line includes a number of vehicles
suitable for fleet applications and government use.

The Benefits of FFV’s
Slide 7
There are a number of motives for considering alternate fuel vehicles. For some fleets it may be
a mandate, for others it may be participation in a Clean Cities Program, or simply a desire to be envi-
ronmentally responsible and / or reduce energy use. There are, of course, options other than FFV’S
such as hybrids and natural gas vehicles. But FFV’s offer some unique advantages. They require no
special or compressed fueling such as with natural gas. They are largely the equivalent of their gaso-
line counterparts. Unlike hybrids they do not cost more or have the added complexity of the electric
drive systems. Should a decision be made to switch between E-85 and gasoline or vice versa, such a
change is readily accommodated. If it is necessary to fuel up away from the central fleet fueling unit
E-85 and the Fleet OperatorPresented by Robert E. Reynolds, Downstream Alternatives Inc.
9
and E-85 is not readily available you can simply fill up with gasoline. Finally service intervals and
maintenance costs are similar to gasoline vehicles.
The Benefits of E-85
E-85 is a liquid fuel so it is handled similar to gasoline. Existing facilities can often be con-
verted from gasoline to E-85 And perhaps most important of all, it appears that ethanol and E-85 may
in the long term, be cheaper than gasoline. There are, of course, numerous public policy benefits as
well including:
Slide 8
E-85 and the Fleet OperatorPresented by Robert E. Reynolds, Downstream Alternatives Inc.
10
Considerations for the Fleet Manager-Fuel Costs per Mile
While the motivation for switching to alternative fuel vehicles and fuels may vary, the fleet
manager needs to consider several things before selecting a specific vehicle/fuel combination.
Slide 9
E-85 and the Fleet OperatorPresented by Robert E. Reynolds, Downstream Alternatives Inc.
11
Obviously the vehicle needs to suit its intended use. For some fleet managers that may be a
Pick -Up, Van or SUV, for others a mid or full size sedan and, in this budget conscience era, for others
perhaps this means a small economy model. FFV’s can fill most of these categories, except that at
present there aren’t many small economy models. Of course FFV’s excel in the cost category because
they have traditionally sold at or near the same price as their gasoline counterparts.
Vehicle maintenance and service frequency is also a consideration because it contributes to the
overall cost of vehicle operation. Once again FFV’s do well in this category because their service
intervals are the same as on the base non-FFV vehicle.
For Centrally Fueled Fleets the manager will need to look at storage and dispensing issues.
Retrofitting or installing an E-85 fueling facility is relatively inexpensive especially when compared to
a compressed gas installation. However, a fleet manager likely will not convert all vehicles at one time.
If they only have one storage tank, but vehicles requiring two different fuels, there will be a need for
new additional equipment or alternative fueling options. I’ll talk more about these issues in greater
detail momentarily.
Vehicle range will be an issue for some fleet managers. Compared to operating on gasoline
FFV’s can only travel about 75% of the distance on a tank of E-85 Rather or not this has any impact is
very fleet, or even fleet segment, specific. Still, FFV’s operating on E-85 will have better range than
gaseous fueled vehicles and can, of course, run on gasoline when circumstances dictate. Ideally the
fuel selected will be widely available. Of course E-85 can be blended at terminals that dispense E10.
As such, it is widely available for bulk purchase for delivery to fleet facilities. However, it is not yet
widely available at retail or card lock facilities so if the fleet is not centrally fueled then fuel availability
would need to be examined in more detail.
Finally, fuel cost on a miles driven basis needs to be considered. This is where things get a little
more complicated. First E-85 is really E75 in the winter, E80 in spring and fall and E-85 in summer.
Ethanol does not contain as much energy as gasoline (lower btu). In fact E-85 (E75, E80) contains
about 73% to 76% the Btu content of gasoline. So the purchase price must be 73% to 76% that of
gasoline to provide the same fuel cost per mile driven.
E-85 and the Fleet OperatorPresented by Robert E. Reynolds, Downstream Alternatives Inc.
12
Slide 10
In May ethanol was at 282.4 ¢pg and gasoline was at 218.4¢. At those prices E-85 would cost
10 to 11 cents more than gasoline and deliver fewer miles per gallon. With gasoline at 218.4¢ pg what
the numbers should look like are this:
E-85 and the Fleet OperatorPresented by Robert E. Reynolds, Downstream Alternatives Inc.
13
Slide 11
In this slide we can see that to achieve parity pricing on a miles driven basis you would need to
purchase E-85 at 159.41 ¢pg (E75 at 166.35 ¢pg) to achieve the same fuel cost per mile.
Obviously if you are purchasing on quotes / bulk fuel contracts you need to negotiate a price for
E-85 that reflects the difference in its energy content. So before you make a decision to convert fleet
fueling equipment you want to be sure that E-85 will be competitively priced.
E-85 and the Fleet OperatorPresented by Robert E. Reynolds, Downstream Alternatives Inc.
14
Considerations For The Fleet Manager – Fuel Specifications
If you contract for bulk purchases of E-85 you want to be sure it will be on specification. The
industry specification for E-85 is ASTM Designation: D5798. Standard Specification for Fuel Ethanol
(Ed 75-Ed 85) for Automotive Spark Ignition Engines.

Slide 13
E-85 and the Fleet OperatorPresented by Robert E. Reynolds, Downstream Alternatives Inc.
16
Slide 14
First the Ed 75 – Ed 85 terminology is simply the technical way of acknowledging that the
ethanol portion of the blend is made up of “denatured ethanol” which itself contains 2% to 5% hydro-
carbons. There are three Classes of E 85 based on volatility needs. In cold climate class 3 is required.
It contains more hydrocarbons to aid with cold start and warm up performance. In summer months
Class 1 or 2 is adequate. The ASTM specifications list the grade requirement by month and by state, or
in some cases portions of a state. For instance in Missouri Class 3 is specified for mid October through
mid April, and Class 2 for mid April to mid May and mid September to mid October. From mid May to
mid September Class 1 is required. These requirements minimize the chance that a fuel fails to provide
adequate cold start and warm up performance. There are also requirements specified in ASTM D5798
that address various areas.
ASTM D5798 also includes the test procedures to test these properties, instructions on sam-
pling techniques, and a discussion of the significance of the specified properties. Obviously these are
E-85 and the Fleet OperatorPresented by Robert E. Reynolds, Downstream Alternatives Inc.
17
not things a fleet operator is going to test for. However, purchase agreements should specify that the E-
85 supplied will meet the most current version of ASTM D5798.
Considerations for the Fleet Manager–Central Fueling Facility Conversions
If you are thinking of converting to E-85 and also converting your central fueling facility to E-
85 (meaning you have identified a source for competitively priced, on spec product) there are some
system requirements that are slightly different than for gasoline. First you must decide if you are
converting existing equipment or installing a new system. If you have multiple tanks and dispensers
you may be able to simply convert existing equipment. If you have only one storage tank it is likely
that you would need to keep it for gasoline storage for existing fleet vehicles. In this case your E-85
fueling system would likely be a new install.
Slide 15
E-85 and the Fleet OperatorPresented by Robert E. Reynolds, Downstream Alternatives Inc.
18
If you are converting, the first issue is the storage tank. Steel tanks are suitable for E-85 Fiber-
glass tanks must be rated for 100% ethanol. We recommend cleaning the tank before conversion.
Ethanol’s solvent effect will loosen / remove built up gums, sediment, etc. You may be able to avoid
this step if you are converting from E10 by raising the level 1st to E 35 then to E 85.
Regular gasoline dispensers have components that are not compatible with E 85. As such a new
retrofitted dispenser is required (or retrofit of an existing dispenser if available). Dispensers should be
equipped with a 1 to 2 micron filter. Finally the dispenser hose and nozzle need to be alcohol compat-
ible. Anything that is rated for use with methanol is also suitable for use with E 85.
As I was preparing this paper, UL was finalizing draft requirements for E 85 dispensing equip-
ment. The applicable standards are UL 87, UL 25 and UL 79.
There are a number of metals compatible with E 85 but there are also many that are not.
Slide 16
Similarly there are plastics and elastomers that are compatible and those that are not.
E-85 and the Fleet OperatorPresented by Robert E. Reynolds, Downstream Alternatives Inc.

Slide 17
New Installations: If you are installing a new facility your system design will be based on real estate
available, local regulations, permitting requirements, and anticipated storage requirements.
E-85 and the Fleet OperatorPresented by Robert E. Reynolds, Downstream Alternatives Inc.
20
Slide 18
Above ground storage tanks (ASTs) are an attractive option where excavating for an under-
ground storage tank (UST) is costly or impossible due to subsurface conditions. AST’s are usually
smaller than UST’s often around 3,000 – 4,000 gallons capacity, although larger sizes are available.
However, smaller delivery size will cause the delivery cost per gallon to increase.
AST’s require secondary containment such as impervious dikes to contain spills, overflow, or
leaks due to tank rupture. State requirements for single wall tanks may differ from those for double
wall tanks. Most permits require a high level alarm and automatic shut off to prevent overfill as well as
either a permanently mounted sight gauge or manual “tank sticking” during unloading.
Underground storage tanks are used more frequently than ASTs. Typical tank sizes are 8,000 to
12,000 gallons. Steel tanks or fiberglass tanks that are UL rated for 100% ethanol can be used. Regu-
lations for USTs storing E-85 are the same as the regulations for storing gasoline.
E-85 and the Fleet OperatorPresented by Robert E. Reynolds, Downstream Alternatives Inc.
21
Obviously, selection of a qualified UST installer is critical. Many states license or otherwise
certify UST installers. Of course, there is a lot more to the UST system than just the tanks. You will
have various piping, electrical, submersible pumps, etc. as well as concrete work. Obviously all
parts of the system in contact with the fuel need to be specified as E 85 compatible.
Above ground the process is similar to the conversion process described earlier. The dis-
penser and all its accessories must be E 85 compatible.
The cost of a new installation can fall in a fairly broad range depending on tank size, excava-
tion difficulties and the type and number of dispensers. I have seen small tank single dispenser
installations below $30,000 up to the $45,000 range.
The AFDC website, which I will provide information on at the end of my presentation, has
actual example quotations for various installations.
You and your contractor should be aware of all codes and standards that must be complied
with.
Slide 19
E-85 and the Fleet OperatorPresented by Robert E. Reynolds, Downstream Alternatives Inc.
22
These include NFPA codes 30 and 30A and Federal Spill Prevention Measures. Many states
also have spill regulations and product delivery laws, and of course there are usually state and local fire
codes. Finally there are hazardous material regulations. Addressing these issues before starting the
project will eliminate any unpleasant surprises.
There are also various permitting requirements. These requirements and the associated costs
should be the responsibility of the installation contractor. So bid specifications and contracts should
specify this.
You may be able to offset some of the cost of installation through various funding sources.
Slide 20
E-85 and the Fleet OperatorPresented by Robert E. Reynolds, Downstream Alternatives Inc.
23
There are federal tax credits available that were included in the 2005 Energy Policy Act and
some states such as Colorado and Kansas have tax credits available for E 85 outlets. However, some of
these may only be available for retail outlets. Other funding sources to check with include the National
Ethanol Vehicle Coalition (NEVC) and the Clean Cities Coalition (if you are in a participating area).
Slide 21
No presentation of this type would be complete without some information on safety and fire
fighting. E 85 is a flammable liquid and should be treated with the same caution as gasoline. This
includes an emergency action plan. You should also issue material safety data sheets (MSDS) to per-
sonnel who might come in contact with the fuel. Your local fire department should be advised which
installations are E 85 since extinguishing an E 85 fire is different than extinguishing a gasoline fire. In
E-85 and the Fleet OperatorPresented by Robert E. Reynolds, Downstream Alternatives Inc.
24
particular, large E 85 fires should be extinguished with an AFFT / ATC fog or foam and water spray.
Additional information on fire fighting is available from the Renewable Fuels Association. For small E
85 fires, carbon dioxide, halon or dry chemical extinguishers marked B, C, BC or ABC should be used.
Turnkey Fueling: One fueling option I did not mention is contractor turnkey fueling. This is where
a contractor brings a truckload of E 85 and fuels the vehicles overnight. Product is metered and
coded by vehicle providing accurate, by vehicle, fueling records. At present I am aware of only a
couple of companies providing this service but as E 85 Fleet Sales increase others may begin to
provide this service. These services can eliminate, or delay, the need for costly installation and may
be particularly attractive during transition from a gasoline only fleet to a flex fuel vehicle fleet.
Obviously I have tried to cover a lot of ground here today and time doesn’t permit going into
extensive detail on every topic. So I want to provide you with a number of information sources
where you can find expanded information on the topics I’ve covered.

By far the most informative website is the Alternate Fuels Data Center. This is a U.S. DOE
sponsored site which has an E-85 Tool Kit that covers nearly every item I have spoken about today.
This site also includes a number of useful links to such sites as the Clean Cities Coalition, NFPA,
EPA’s UST site, the EIA, EPACT, OSHA and many others. The National Ethanol Vehicle Coalition
also has a website with a variety of information on E-85 and flex fuel vehicles. The Renewable
Fuels Association website has a number of useful documents and information papers. Finally if you
wish to acquire a copy of ASTM D5798 you can also go to the ASTM website. Collectively these
websites and their links will get you about anything you need to know.
I hope the material covered proves useful to you. Thank you and I would be happy to try and
answer your questions if the schedule permits.
