July marks two important milestones that set gas-fired generation on its course to becoming a dominant form of power generation: commercial operation of the world’s first industrial gas turbine in Neuchâtel, Switzerland, in 1939, and commercial operation of the first gas turbine in the U.S. used to generate electric power—a 3.5-MW General Electric (GE) unit […]

Power plant SO2 and NOx emissions have decreased 92% and 84%, respectively, since Congress passed major amendments to the Clean Air Act in 1990. Meanwhile, mercury air emissions from power plants have decreased 90% since 2000, as federal limits on mercury and other hazardous air pollutants from coal-fired power plants went into effect in 2015. […]

Since the 1940s, when General Electric (GE), launched its gas turbine operations, the company has pioneered and commercialized a lengthy list of gas turbine technologies, large and small. As the decarbonization movement gains pace and more renewables flood the landscape, the company’s gas turbines have taken on new crucial roles to provide dispatchability and flexibility. […]

The Environmental Protection Agency (EPA) will refrain from amending the National Ambient Air Quality Standards (NAAQS) for sulfur dioxide (SO2), retaining a 2010 rule, which it said adequately protects public health.  The agency on Feb. 25 said in a notice that a periodically required review of the primary—or health-based—rule concluded no revision was necessary. The […]

For many years, air pollution control (APC) rules and regulations have governed the design and economics of the world’s power generation fleet. These rules have had a tremendous impact, improving air quality

In a bid to tamp down pollution, India’s government in December 2015 notified the country’s coal generators they would need to meet—for the first time—new emissions limits for nitrogen oxides (NOx), sulfur dioxide (SO2), and mercury, as well as tightened limits for particulate matter (PM) and water consumption. The gazetted notification gave new plants until […]

Eight northeastern states are again suing the Environmental Protection Agency (EPA) to force the agency to slash emissions of nitrogen oxides (NOx) and volatile organic compounds (VOCs) blowing in from power plants and other sources in nine “upwind” Midwestern and southern states. The Ozone Transport Region, which was established by Congress under Section 184 of […]

The world’s power sector last year emitted a third of global sulfur dioxide (SO2) emissions, 14% of nitrogen oxides (NOx), and 5% of total particulate emissions (PM2.5), but those emission values have fallen drastically over the last decade even though coal power generation has seen a surge, the International Energy Agency (IEA) said in a […]

India and 73 other countries submitted their carbon emission reduction targets for 2025 and 2030—or Intended Nationally Determined Contributions (INDCs)—ahead of the deadline last week, with just two months remaining until talks to confront climate change are due to begin in Paris.  The United Nations (UN) has so far received 120 separate pledges covering 147 […]
