2. New Generation Biomass Overview
Our mission is to develop, own and operate
biomass, renewable energy and biofuel facilities:
– Biomass Power Generation Facilities
– Combined Heat and Power (CHP) – Wood or
Natural Gas
– Anaerobic Digester and Landfill Gas/Power
– Biofuels

3. Biomass Energy Generation

4. Biomass vs Other Renewables and
Fossil Fuels

5. New Generation Biomass
Technology Choices
• Woody or crop residue biomass power production
– New plants
– Conversion of existing coal plants to biomass
• Torrefied wood co-firing with coal in existing power
plants – up to 100% replacement
• Biomass direct injection – up to 15%
• Biomass mixing with coal for co-firing – up to 5%
• Municipal Solid Waste – Waste to Energy
• Anaerobic digester power production and biogas
production
• Landfill gas power and biogas production

6. Woody Biomass Power Generation
Typical Biomass Plant – 15 MW
Truck Dump

7. New Generation Biomass
Woody Biomass Sources
Sources:
• Forest management (fire reduction) thinning
• Beetle kill
• Sawmill waste
• Wood processing waste
• Wood diverted from landfills
• Used railroad ties
• Noxious or invasive species
• Construction and demolition
• Orchard prunings and nut shells
• Paper mill waste
• Brush clearing - juniper

8. Conversion of Coal Plants to
Biomass

9. New Generation Biomass
Coal Plant Conversion to Biomass
• NGB can Convert Existing Coal Power Plants to
Biomass for Production of Renewable Energy
• Utility Receives Payment for Existing Plant
• Long Term Contract for Renewable Electricity at
Current Rates
• Existing Staff is Transitioned to New Biomass
Operation – No Lost Jobs

10. Torrefied Woody Biomass

11. Torrefied Wood Co-Firing in Existing
Coal Power Plants
Heat &
Residence Torrefied
Time
Wood –
Wood Chips
Power Plant
Super Fuel

12. Torrefied Wood Co-Firing with Coal in
Existing Power Plants
• No Plant Modifications Needed
• Torrefied Wood Blends With Coal – Same Density,
Same Heat Value
• Torrefied Wood Pulverizes in PC Plants Like Coal
• Repels Water – Can be Stored Outside for Long
Periods
• Can be Made from Any Wood

16. Torrefied Wood Co-Firing with Coal in
Existing Power Plants
Option 1
• NGB can Develop New Facilities near the Power
Plant to Produce Torrefied Wood
• NGB has Access to Technology for Torrefied
Wood

17. Torrefied Wood Co-Firing with Coal in
Existing Power Plants
Option 2
• NGB can Arrange Contracts for Purchase of
Torrefied Wood in the US and Deliver to Europe
• NGB Can First Provide Torrefied Wood for a Test
Co-Firing at the Power Plant

18. Torrefied Wood Co-Firing with Coal in
Existing Power Plants
Path Forward:
• Torrefied Wood Test Co-Firing at the Power
Plant
• LOI for Torrefied Wood Supply Contract

19. Cofiring of Biomass in Coal Plants

20. New Generation Biomass
Cofiring Biomass in Coal Plants
• Switchgrass Direct
Injection
• Alabama Power - Plant
Gadsen
• Switchgrass is Ground
and injected in separate
burner
• 10% Renewable Energy
production

21. Waste to Energy

22. New Generation Biomass
Waste to Energy Benefits
• Reduces Waste Going
to Landfills
• High Power Availability
• WTE is Accepted in EU and US as Renewable
Energy
• Technology is Conventional Combustion or
Plasma Gasification

23. New Generation Biomass
Conventional Waste to Energy Facility
Technology:
Material Recycling, Production of a Refuse
Derived Fuel and Conventional Combustion
•Plant Size: 20 MW
•Waste Disposal: 340,000 Ton/y*
•Electricity Produced: 150,000,000 kWh/y
*No tires included

24. New Generation Biomass
Conventional Waste to Energy Process

25. Anaerobic Digester Energy

26. New Generation Biomass
Anaerobic Digester Energy Benefits
• Fuel Supply is Inexpensive
and Plentiful
• Solves Difficult Waste Entec Pig Manure Plant– 12 MW
Problems
• Plants Use Biodegradable Wastes that Can’t Be
Converted to Energy Economically Otherwise
• Great for Manure Conversion to Biogas or Power
• High Availability – Base Load Power
• AD accepted in US and EU as Renewable Energy

27. Anaerobic Digester Energy Facility
Typical Woody Biomass Plant – 15 MW
Truck Dump
3.2 MW requires
about 3 acres of
landody Biomass

28. Landfill Gas Energy

29. Landfill Gas (LFG)
• Landfill Gas Occurs from the Decomposition of
Organic Material in Landfills
• LFG Power Plant Sizes Typically Range from
0.25 MW to 50 MW
• LFG is 50% Methane/45% CO2/ 5% N2
• Can be used to generate power, or cleaned up
for pipeline quality natural gas

30. Landfill Gas Power Generation
Landfill Gas Energy Projects and
Candidate Landfills

31. Landfill Gas
• Landfill Gas Power Generation Cost is Very
Competitive
• Reciprocating Engines are Used to Generate
Electricity – Modular and Cost Effective
• Gas Cleanup is the only Major O&M Cost
• Remote Operation

32. New Generation Biomass
