Transcript Biodiesel

Objectives
 Describe how biodiesel may help improve public
health
 Describe the benefits of biodiesel to the
environment
 Explain how biodiesel may help stimulate the
economy
 Describe what energy security is and how using
biodiesel can help attain it
 Explain the future of biodiesel
 Explain the suggested actions to support biodiesel
2
Why Consider Biodiesel?
 Cleaner-burning fuel
 Domestically produced from renewable
resources
 Promotes energy self-sufficiency
 Creation of jobs in agricultural sector
 Almost any diesel vehicle can use biodiesel
with little or no modification
 Easiest fuel to implement due to existing
infrastructure and blending

Advantages of Biodiesel





Energy self-sufficiency
Creation of jobs within the U.S.
Reduced exhaust emissions
Use of domestically grown crops
Growth within the U.S. agricultural sector
Special Note:
NEVER use any clean or used grease or vegetable oil that has not been processed for
biodiesel usage.

Biodiesel Benefits
 There are many benefits of using biodiesel
to fuel vehicles:




Betterment of health and environment
Benefits to the U.S. economy
National energy security
Reduce dependence on foreign oil
7
Health Benefits
 Biodegradable and nontoxic
 Exhaust hot as strong smelling as conventional
diesel
 No threat to human health
 Reduces emissions that cause respiratory
illness
 In 2000, biodiesel became only alternative fuel
in U.S. to complete EPA health effects testing
under the Clean Air Act
8
Did You Know?
The direct benefits from the 1990 Clean
Air Act Amendments are estimated to
reach almost $2 trillion for the year
2020, a figure that dwarfs the direct
costs of implementation ($65 billion).

Environmental Benefits
 Carbon-neutral
 Plants remove carbon dioxide
from the atmosphere
 Made from plant material

 GHG emissions are reduced because biodiesel releases
carbon dioxide that crops originally removed
 According to EPA, biodiesel can reduce GHG
emissions
 Can be used with SCR systems to reduce NOx
emissions, which lead to acid rain
10
Did You Know?
Biodiesel is less toxic than table salt
and biodegrades as fast as sugar.

11
Economic Benefits
 Supports U.S. agriculture and rural
communities
 According to National Biodiesel Board, the
biodiesel industry is expected to create an
additional 74,000 jobs by 2015
 Will increase household income by $4 billion
 Will generate nearly $7.3 billion in GDP
12
Energy Security Benefits
 U.S. is one of the greatest agricultural
product exporters
 Increased demand for transportation
 Dependency of foreign oil to meet
transportation demand
 Use of existing agricultural production and
infrastructure

Renewable Benefits
 Renewable = can be produced and
replenished
 Energy balance = ratio of energy required to
produce/distribute fuel compared to the
amount of energy released when used
 Very high energy balance compared to other
fuels
 3.2 units of renewable energy
 Compared to diesel = 0.83 units
15
Biodiesel – Today and Tomorrow
 Biodiesel has
contributed to the
domestic economy
 Currently roughly
52,000 jobs in
biodiesel industry
 Currently 800
million gallons of
biodiesel produced
 Growing consumer
popularity
 Production of
biodiesel to
increase to 900
million gallons by
2015
 Will support $7.3
million of GDP
 Growth in fleets,
school districts
16
Clean School Bus Program
 Reduce children’s exposure to diesel exhaust and
the amount of air pollution created by diesel
school buses
 School bus facts:
 24 million children in the U.S. ride school buses daily
 On average, students spend 1.5 hours on the school
bus every day
 School buses travel more than 4 billion miles each year
 School buses may leave their engines idling near
schools – this creates indoor and outdoor air pollution
problems
17
The Future of Biodiesel
 Biodiesel will continue supplementing diesel
technology
 Higher blends available at fueling stations
(from B5 to B20)
 Changes at the pump – production increases,
costs decrease
 50/50 mixtures

Suggested Actions
 Recognize that biodiesel is not ethanol
 Become aware of what vehicles are capable of
using biodiesel
 Check for biodiesel emblem on vehicle
 Become a biodiesel advocate
 Check with school districts to see if cleaner
energy is used in transportation
 Encourage school board members and
government officials to attend PRT workshops

Did You Know?
There are roughly 450,000 public
school buses in the United States;
390,000 are powered by diesel fuel.

Test Your Knowledge
1.
Give an example of a biodiesel vehicle that is
successfully reducing carbon emissions.
2. True or False: Biodiesel is the only alternative fuel to
go through the health effects tests under the Clean Air
Act?
3. True or False: The key difference to remember about
biodiesel and ethanol is that biodiesel is meant to run
in gasoline engines, while ethanol will run in diesel
engines.
4. True or False: The majority of diesel vehicle owners
don’t realize that their car may run on biodiesel.
