Emissions reduction benefits from hydrogen addition to midsize gas turbine feedstocks

The use of hydrogen addition to the natural gas feedstocks of midsize (30–150 MW) gas turbines was analyzed as a method of reducing nitrogen oxides (NOxNOx). The costs of hydrogen addition as a function of its ability to reduce NOxNOx were investigated. Hydrogen addition was evaluated against current control technologies for both existing and new systems to determine its benefits and market feasibility. Markets for NOxNOx emissions credits currently exist in California and the Northeast States and are expected to grow; therefore, potential sale of emissions credits for volunteer retrofits was also included in this study.
