Biodiesel
Basics
Presented by
Stuart Stranahan
President, Olympic BioFuels
Introduction
- Mono Alkyl Esters
of Long Chain Fatty Acids
- High performance substitute
for petroleum diesel fuel made from vegetable oils
- Renewable, cleaner
burning
- Can be made from domestic
sources
What is Biodiesel?
Introduction
What is Biodiesel?
- It can be used in any
diesel engine with
little or no modification
- Engines built before
1993 may require
some natural rubber parts to be replaced
- Fits into existing
infrastructure
- Can be blended with
petroleum at any ratio
Introduction
What is Biodiesel?
Benefits:
- Burns more efficiently; oxidized
fuel, high lubricity
- Increased fuel economy
- Increased engine life
- Lower maintenance costs
Introduction
What is Biodiesel?
Drawbacks:
- Slightly higher “gel”
point than petro-diesel
- Oxidative instability →
Long-term storage
issues

Both can be addressed with additives

Energy Balance
Source:
How to Make Biodiesel by Halle, Carter. Pub LILI
- Petroleum requires
~1 BTU of energy spent
to produce only 0.8 usable BTU's of liquid
fuel
- For that same
BTU of energy spent,
Biodiesel returns ~3.2 BTU's = approx.
4 X more usable energy than petroleum
The energy for biodiesel
comes
from the Sun -- for free.
Environment
Carbon Neutral
- Carbon emissions from Petroleum
are
extracted from the Earth and persist in
the atmosphere
- Carbon from Biodiesel
is reabsorbed by
the plants grown for vegetable oils
Other
Impacts
- Human Health Impact:
Biodiesel is the
only fuel to have a complete human health
impact study done on it. NBB & EPA
- Biodiesel was found
to be:
- Non-toxic
- Non-hazardous
- Biodegradable

The
Answer?
- Biodiesel is not
THE answer to the world's energy demands.
- We must explore and
develop ALL renewable energy sources:
- Biofuels (biodiesel,
ethanol, ...)
- Solar (Photovoltaic
and passive)
- Wind
- Geothermal
- Tidal

The
Answer?
- Biodiesel is not
THE answer to the world's energy demands
- However, we will require
liquid fuels for transportation for the foreseeable future.
- Trucking
- Railways
- Shipping
- Mass transit
- Personal vehicles

The
Answer?
- Biodiesel is not
THE answer to the world's energy demands
- The Ethanol industry
is experiencing some difficulties.
- Hydrogen cells are
not proven and there is no existing infrastructure for it.
- Quality issues

Our
Plan
Small Business,
Big Impact
- Olympic Biofuels is
building a small-scale
biodiesel production plant in Kitsap County
- When we prove the business
model works,
we will replicate it
-
Producing locally reduces dependence outside the
community and boosts commerce, keeping
revenues in the region.
Our
Plan
How Much?
2006-2007:
500,000 gallons of biodiesel
50,000
gallons of glycerin
A modest plan that can be adjusted.
2008-2009:
1,000,000 gallons of biodiesel
100,000 gallons of glycerin
Interior (e.g. brewery)
The equipment in a biodiesel plant is
similar to a brewery
Hood Canal Brewery equipment: A Neighbor!
Our tanks; a little bigger.
