Ontario Opportunity
5.6 Million ha of agricultural land
Based on the German example, the integrateduse for production of
food, feed and energy cropscould generate 3700 m3/ha/year of
methane
This is enough gas for almost 9000 MW ofelectrical capacity
Biogas power plants with gas storage can operateas peaking
plants

Economics: SOP Calculation
Power produced: 335 kW
Power price: $0.11/kWh
Annual operating hours: 8300
Annual revenues: $305,855
Fuel Cost: $0
Maintenance costs (59,000 hrs): $4.04/oph
Annual Maintenance costs: $33,532/yr
Unforeseen allowance: $15,000/yr
Total annual costs: $48,532/yr
Net revenues: $305,855 - $48,532 = $257,323
Capital cost estimate: $900,000
Simple Payback: $900,000 / $257,323 = 3.5 years

Can a Biogas CHP plant provide CO2 fertilization?
With biogas containing >40% CO2 it would be attractive
for CO2 fertilization
Primary challenge is to maintain a consistent fuelquality and
composition
Fuel treatment is critical
