Developing Florida Biomass Resources

Florida has ~10% of US

biomass resources

51% statewide tree coverage

80% of it is commercial

15 million acres of forest land

10 million acres of farm land

• #1 in sugarcane and citrus

• #1 in forest residues

• #1 in urban wood waste

• #2 in vegetable (waste)

100MW Biomass Power Plant - Gainesville

Renewable Energy Center

Biomass to ethanol plant - INEOS

Algae to ethanol pilot plant – Algenol

University of Florida cellulosic ethanol biorefinery

Climate allows year around

energy crop growth, high

crop yield and conversion

efficiency

Scalable Algae Cultivation

Open pond Closed photobioreactor (PBR)

• Low investment

• Low biomass density (huge

water volume to process)

• Low yield

• High investment

• High biomass density

• High yield

A plastic platform with

proprietary integrated aeration

system – floating on water body

Innovative Approach: Horizontal Bioreactor (HBR)

• Low capital cost

• High cell density & productivity

• A fraction of water use (< 1/4th)

• Lower cost of downstream processing

• Thermal control

• Contamination barrier

• Floating (or on the ground)

• Readily scalable (modular)

Power, Water, Heat, and Cooling By Dr. Lear

• Single unit for power, water, cooling, heat

• Life cycle cost advantage

• Increased design efficiency

Fuel and Emissions

• Ultra-low emissions

• Fuel flexibility

• Cost-driven fuel choices

• Enables opportunity fuels

• Enhanced energy security

Grid Impact

• Sub-second response time

• High part-load efficiency

• Operate ~75% load

• Vary output for frequency control

• Reduce spinning reserves

• Increased stability, decreased cost
