Universal sensitivity to our environment and environmental considerations have led to the development of projects that not only minimize GHG (Green House Gas) emissions, but also help to displace GHG emissions from existing plants as well as other emissions sources. Thus, one of the more significant advantages for gas turbine, combined cycles and gas reciprocating engines is the potential for GHG reductions as compared to less efficient systems. This monetization of GHG reductions serves as a significant driver/incentive for the development of gas-turbine and gas-engine-based cogeneration applications. Cogeneration applications range from industrial applications such as pulp and paper mills, steel mills, and chemical processing plants to commercial and civic-based applications like.
