Biomass/Biodiesel Jessica Baker, Jeanne Cannon, Arthur Bryant
What is it?● Biomass
○ biological material derived from living, or recently living organisms.
○ Main type = Lignocellulosic Biomass○ Wood wastes
● Biodiesel ○ biofuel intended as a substitute for
diesel.
What is it from? Where is it?
Technical Impediments
• High up-front capital costso lack of profitabilityo feedstock transportation costs
• Not enough policy incentives • Change into sugar
What modifications (if any) must be made to existing diesel engines to get them to run on biodiesel?
• Can be used in standard diesel engines.o NOT CARS!o Some Companies void warranty for using biodiesel
• Mix biodiesel with regular fuel• Biodiesel -- better for our engines!
Environmental Impacts• Deforestation • Uses soil degradation• Massive land use*Biodiesel is one of many
alternative fuel options that has the potential to help reduce oil dependence and global warming pollution. But done wrong, biodiesel can actually increase global warming pollution and cause other environmental problems, such as deforestation and loss of biodiversity.
Pros
•Truly a renewable fuel•Widely available and naturally
distributed•Generally low cost inputs•Abundant supply•Can be domestically produced for
energy independence•Low carbon, cleaner than fossil fuels•Can convert waste into energy, helping
to deal with waste
Cons
•Energy intensive to produce. In some •cases, with little or no net gain.•Land utilization can be considerable.
Can lead to deforestation.•Requires water to grow•Not totally clean when burned (NOx,
soot, ash, CO, CO2)•May compete directly with food
production (e.g. corn, soy)•Some fuels are seasonal•Heavy feedstocks require energy to
transport.•Overall process can be expensive•Some methane and CO2 are emitted
during production•Not easily scalable
