In the past, reciprocating engines had proven to be a more cost effective cogeneration technology at wastewater treatment facilities when compared to fuel cells despite having a much lower electrical efficiency. However tightening air permit regulations have created numerous obstacles for entities that looking to install engine-generators, as in many cases they would be required to either operate them as standby or provide them with Selective Catalytic Reduction (SCR) systems and CO catalysts. These obstacles in conjunction with available grant funding through the California Self-Generation Incentive Program (SGIP) have made fuel cells a more economical cogeneration technology that are also environmentally friendly.
