Alternative Fuel Products
Ethanol
Combinations
Ethanol is a fuel blending component that is used widely by major
oil companies and distributors. According to Ethanol producer Iogen
(www.iogen.ca),
approximately 12% of all US gasoline is currently blended with Ethanol.
Ethanol is considered an 'alternative' fuel component, as it can
be produced from domestically-produced agricultural products. Ethanol
has been used in low concentrations (less than 10%) with no changes
in engine components or fuel handling and delivery systems. Ethanol
can be used in higher concentrations (up to 85%) in specially-designed
'Flexible Fuel Vehicles', described below.
E10 refers to a gasoline-based ethanol product. This typically
has a combination of 90% gasoline and 10% ethanol, but the percentage
of ethanol can range from 5.7% to 10% in accordance with the specifications
of the customer. E10 is commonly used throughout the United States
and can be used in all gasoline vehicles without engine modification.
E85 (85% ethanol, 15% gasoline) is currently available at
approximately 400 gas station pumps in the United States, according
to the National Ethanol Vehicle Coalition (www.e85fuel.com). Flexible-Fuel
Vehicles (FFVs) are designed to run on regular unleaded or any ethanol
fuel blend up to 85% Ethanol. Special onboard diagnostics "read"
the fuel blend, enabling drivers to fuel with E85 or regular unleaded
if E85 is not available. Today, Ford Motor Company, General Motors,
and Daimler-Chrysler Corporation all offer E85 engines as standard
equipment in certain vehicles.
These vehicles come with the same factory warranties as gasoline
vehicles. Ethanol has lower energy content vs. gasoline, and is
'hygroscopic', meaning that it can draw water into the fuel from
the surrounding air. These characteristics can create lower fuel
efficiency and handling problems in Ethanol-based fuels. ReFuel's
technology is intended to make up for the typical loss of performance
with ethanol blends. ReFuel's technology is designed to enable a
clear homogenous solution, eliminating typical problems with water
that cause phase separation, and thereby improving combustion.
Biodiesel Combinations
Biodiesel is an "alternative" fuel component that can be produced
from domestically grown Soybean and other oil crops, as well as
waste oil and animal fats. Biodiesel requires no engine modifications
or changes in the fuel handling and delivery systems. Biodiesel
delivers similar horsepower, torque, and miles per gallon as conventional
diesel, while producing significantly lower emissions of Carbon
Monoxide, black smoke, and particulate matter.
B20 (blend of 20% Biodiesel with 80% conventional diesel)
has limited distribution in the US currently, although all diesel
vehicles can use this fuel. According to the National Biodiesel
Board, usage of Biodiesel in the US was 30 million gallons in 2004,
vs. a total on-road diesel consumption of 34 billion gallons, according
to the Energy Information Administration. Federal and state fleets
are mandated to use B20 if available, to meet their targets for
the Energy Policy Act and EO13149 compliance (discussed below).
According to the EPA, one drawback with Biodiesel is that it increases
emissions of Nitrous Oxides. ReFuel's technology is designed to
enhance the performance of B20 by eliminating this Nitrous Oxide
increase, while also substantially increasing the reduction of black
smoke and particulates.
