Nitrogen Oxides
Byproducts generated during high-temperature combustion in gas-fired generator units. They are respiratory irritants and precursors to ozone and PM2.5, with negative effects on air quality and public health.
Timeline (last 90 days)
Units converted from older engines often retain the original combustor design, resulting in noticeably higher NOx emission concentrations, and some models require the addition of selective catalytic reduction equipment to meet local environmental permits.
Gas-fired power generation releases pollutants such as nitrogen oxides (NOx).
Ground-level ozone is formed by photochemical reactions of nitrogen oxides and volatile organic compounds under sunlight, and natural gas units still emit considerable NOx in Texas summers with high temperatures and strong sunshine, boosting ozone formation.
Part of PM2.5 comes from secondary particulate matter formed through atmospheric transformation of sulfur dioxide and nitrogen oxides emitted by power generation.
