Back Story


Several Years Earlier The District Had Exposed Shortcomings of the Aftertreatment Systems for Natural Gas Engines
In 2008 Issued New Regulation for DG Technologies (Rule 1110.2)


Based on “CARB 2007”
Combined Heat in Power in CA Facing Uncertain Future



Compliance of Engine-Base Systems Not Feasible
Emerging Technologies Still Constrained by Cost, Other Shortcomings
No Viable CHP Option in CA
Project Outcome
17

Faced Intractable Problem
Price of Very Low NOx is High CO
 Price of Low CO is High NOx



Final Stages of Project Produced Unexpected
Breakthrough
Highly Positive Attributes
Easily Commercialized
 Modest Cost/Design Impact
 No Significant Performance Penalty
 Appears Transferable to Other Engines
