  1. Green EnergyTrash to Gas to Electricity Jay Babin OWT Thailand

  2. Trash to Gas to Electricity • Use Landfill Gas (LFG) to power an engine to run a generator to produce electricity • Electricity can be used “in-house” or sold to the grid • More gas produced means more power (potentially) • More gas captured means more power • Over 1,200 LFG to energy projects world-wide • From 0.5 MW to >50 MW

  3. Trash to Gas to Electricity • Organic material in landfills will biodegrade. • With oxygen present produce carbon dioxide (CO2) and water • Without oxygen (anaerobic) produce methane (CH4), CO2, and water • Thus need to promote anaerobic biodegradation • Couple with enhanced recovery

  4. Sanitary Landfill Source: BAGCHI Waste Management

  5. LFG Utilization (Trash to Cash)

  6. Puenta Hills , 50 MW

  7. Trash to Gas to Electricity • Landfill gas consists of CH4 (50-60%) CO2 (35-45) and other trace gases (H2S, O2) • Must optimize both gas production as well as gas collection • Collect the gas (horizontal and/or vertical wells) • Pre-treatment (KOP) to remove water • Either Flare • Further treatment (filters/cooler) then generate electricity

  8. LFG Generation for 3,000 TPD to 2010

  9. LFGE Economics in Thailand • Power Pricing -three components: • VSPP Standard Pricing: • Supply • Peak: THB 2.9278/kWh • Off-peak: THB 1.1154/kWh • assume 2.02 Bt/KWh • Ft charge: • THB 0.9255/kWh • Adder: • THB 2.5/kWh • Total of 5.4471 Bt/kWh • VSPP Power Purchase Agreement (PPA)

  10. LFG Economics in Thailand • 1 MW/year Electricity produced provides 7,446,000 kWh (assume 85% available) • = 40,559,106 THB/year • =1,329,806 $US/year @ 30.5 THB/$US

  11. Electricity Revenue (3,000 TPD) • Total electricity revenue is $US 140 Million

  12. GHG Revenue • 130 m3 of = 1 Tonne of CO2 equivalents • GHG income is 46 M $US • TOTAL Revenue = 186 M $US

  13. Costs • Extremely variable • Power costs ~750 K/MW (7.5 M $US) • Gas Collection Infrastructure 1 M $US/MW = 10 M $US • Infrastructure (compound) cost (~400 K/MW) 4 M $US • Labour 1 M $US/year = 22 M $US • O&M 1 M $US/year = 22 M $US • Total 65.5 M $US • Excluding Gas rights (negotiable)

  14. Economics • Revenue = 186 M $US • Cost = 65.5 M $US • Net (excluding gas rights) is 120.5 M $US
