Process Output History

→ Longest History→ Highest level of Pollutant

i.e. 250tn for 20MW→ No Fuel Flexibility

→ Latest Advancement (10+ years)→ Lowest possible emissions

i.e.10 to 50tn for 20MW→ Widest range of fuel flexibility

→ Extensive history & use→ Controlled Emissions

i.e. 50 to100tn for 20MW→ Limited Fuel Flexibility

→ Short History (30+ years)→ Controlled Emissions

i.e.50 to 100tn for 20MW→ Limited fuel Flexibility

Gasification – A Proven Technology

Advanced Gasification Technology – Key Points

Standard gasification is a high heat partial burn process which breaks down feedstock into it’s basic gaseous elements

Advanced Gasification is a pryolysis process without oxygen or burning which:

offers up to 35% greater efficiency over stoker technology

Produces a reduced emission of 98% below conventional fossil fuel plants & 40% below conventional biomass plants.

Can accommodate a variety of organic feedstock of varying moisture content without impacting Btu content.

Gasification to advanced gasification improvements have been provided by world renowned programs such as: Battelle Labs, NREL, U.S. Department of Energy

At completion, the biomass material is reduced to a minimal inert ash residue with multiple commercial use. (road bed material, landfill fillers, fertilizer extenders, etc)

When additional or replacement fuels are required:

Advanced Gasification = More Fuel Flexibility

“Clean” C&D debris – Includes road & land clearing debris, industry waste (palates, sawdust, paper waste, etc), felled storm debris, urban biomass wastes

• excludes painted and CCA treated wood

Forest Wood Waste – supports proper forest management, is easily processed, and offers good BTU value

Rice hulls & bagasse – an excellent fuel source and beneficial alternative to burning

Energy Crops – such as switch grass and Arundo Donax • Can be grown providing a stable fuel source• provides new industry opportunities

Chicken litter and agricultural waste offer:• high output feedstock• ash becomes usable fertilizer• removes land spread issues

7

Process Flow• Organic feedstock at 3”-

is fed thru a hopper and through an air lock

• In the air lock nitrogen purges out the oxygen

• Blended with steam the feedstock is mixed with 18000f heat

• As the heat mixes an instantaneous reaction “gasifies” the feedstock breaking it down into it’s basic elemental gases

• Cyclones separate the Syngas and any Char

• Gas & char is burned in the combustor generating heat sent to the gasifier

• Closing set to follow receipt of final air permit and interconnection agreement

Feedstock Contracted• Multiple contracts to be signed by using the advantage of below market landfill rates

Permanent financing completed

Equipment Ordered

Construction Ground-breaking• Site work commences

Project Site• In escrow pending financial close

Project shakedown• Systems performance tested

• Output, emissions, feed systems all tested to spec.

• Following acceptable runs –BG&E begins PPA services

Permitting review• Local and federal requirements reviewed during PPA/EPA stage

• Emission requirements & limits

• Other permit issues

Feedstock identified• Preliminary Analysis for availability and cost

Forsyth Power Project – Technology Emission Driven

BG&E selected technology is an EPI starved air fluid bed gasifier coupled with an InDeck recovery boiler.

Back-end emissions controls include a hot ESP followed by a CO2 catalyst and SCR to manage NOx

540 DTPD produces 268 MMBTU/Hr of steam at 9500 F and 1215 psi which directly feeds a 32 MW STG

Project Construction time is 15 to 18 months from ground breaking thru commissioning

12

Technology Supports Feedstock Sources

Extensive private and public studies provided initial support for project and indicated what, where and how much was available.

Selected Feedstock: “Clean” C&D debris – industry waste (palates, sawdust, paper waste, etc), forestry mgmt waste, felled storm debris, urban biomass wastes (from land clearing, landscaping, trimmings, yard biomass, etc), creosote treated woods (telephone poles, RR Ties, etc),

• excludes painted and CCA treated wood

Future Fuel Alternatives

Chicken litter and agricultural waste offers:• high output feedstock• ash becomes usable fertilizer• removes land spread issues

13

Location and partnership with local landfill provides:

Ability to manage landfill tipping fees to attract local wood waste for feedstock

21 days of covered fuel to allow natural drying and plentiful onsite reserves

potential added revenue (from tipping fees) to offset project fuel processing costs

Provides existing staff (at landfill) reducing project fuel management

Solution for ash residue from project
