BioCNG Overview
BioCNG, LLC
Sales and Marketing for BioCNG
Formed in 2010-First system was piloted at the Dane
County Landfill in Madison WI
Headquarters in Madison, WI
Unison Solutions, LLC - Exclusive manufacturer of the
BioCNG system
Cornerstone Environmental Group-Engineering Services
Design
Project Management
Permitting
Energy Values to Consider
Gasoline= 33.4 kWh/gallon energy content
$0.12/kWh @ $4.00/gallon
CNG
$0.07/kWh@ $2.50/gasoline gallon
equivalent (GGE)
Energy Conversion
30 to 40% of biogas energy can be
converted to electricity
70 to 90+% of biogas methane can be
recovered as CNG vehicle fuel
O & M Cost Example
Biogas upgrading= $0.36/GGE
CNG Fueling Station= $0.20/GGE
$0.56/GGE
$0.017/kWh Compare to co-generation.
Characteristics of Biogas
Projects
Small scale producers of biogas
High quality, low contaminant gas
May have a captive vehicle fleet
Trucks & Buses Shifting To CNG: Cleaner, Quieter & Cheaper Fuel Fleets, Communities & Drivers Love Them

Fuel Type and Pathway
Carbon Intensity for Fuels and Renewable Substitute gCO2e/MJ
Biogas-to-CNG Benefits
• Green Fueling Infrastructure
– Distributed cleaner, greener infrastructure
• Greenhouse gas reductions
– Negative Carbon Intensity Pathway
• Homegrown Fuel
– Fuel savings (and credits) accrue to local public and private entities
– Infrastructure primarily from local sources - GC, electric,
construction, permitting, fueling station
• Significant cost savings
– 50-75% savings over current gas/diesel cost
• Control and distributed source
– Fuel cost locked in for 15-20 years
Biogas-to-CNG Summary
Low cost fuel and fixed long term
Short-term pay back with w/RINS and credits
Compatible with all CNG infrastructure
Greenest fuel
Fits the scale of digester projects
