Quadrogen Overview
Quadrogen has developed proprietary biogas clean-up technology and H2 Booster technology with support from NRC-IRAP.
The full-scale sub-megawatt class biogas clean-up unit has been in operation for more than 2 ½ years at OCSD WWTP, California.
Received the Purchase Order for US $ 1.0 million to clean-up biogas for a project in Wyoming, USA.
A $7.5million Quad-generation Demonstration project using landfill gas is in progress. The project is supported by SDTC, BC ICE Fund, BCBN, BC Investment Agriculture Foundation and NRC-IRAP.
Multiple sites under consideration for projects in Europe.

Silica deposits in engine from siloxanes in fuel
Biogas:50 - 60% Methane35 - 40% Carbon Dioxide0-11% Nitrogen
Case Study:Landfill Gas Cogeneration7.4 MWe installed capacity1.3 ¢/kWh maintenance cost< 70% availability of engines Annual Loss of Revenue:$1.62 million@ 70% avail. and 10 ¢/kWh
Biogas is green but not clean

15,000+ hours of operation of IBCS at OCSD WWTP
Performance Since June 2011, the system has been running successfully. The unit has accumulated more than 15,000 hours of operation
at OCSD and processed more than 18 million cubic feet of biogas. We continue to receive data from FuelCell Energy, Inc.
High level of performance being maintained exceeding the customer target.
> All Sulfur species < 25 ppbv> All Siloxanes below non detectable level (< 100 ppbv)> All VOCs below non detectable level (< 10 ppbv)> All halides below non detectable level (< 10 ppbv)
No major maintenance work has been done on the system yet.

Inputs Landfill Gas: ~ 100 standard cubic feet per minute
(MAXIM pipeline carries up to 3,300 scfm) Air: ~2,500 lb/hr Water: ~ 1 gallon per minute for fuel cell
Outputs Up to 300 kW electrical, 0.36 GJ/hr thermal, 100 kg/day of renewable
hydrogen, produced on demand Fuel cell exhaust: ~ 75% N2, 13% CO2, 8% O2, 4% steam
(negligible NOx, SOx, CO, PM10, VOCs) Condensate from LFG: ~ 0.25 gallons per hour, collected in above-grade
tanks emptied periodically by a liquid-waste services contractor. LFG contaminants adsorbed on long-lasting media (2+ yrs), then spent
media is vacuumed into a solid waste truck for off-site recycling or disposal.
