In 2023, operators plan to retire 15.6 gigawatts (GW) of electric-generating capacity in the United States, mostly natural gas-fired (6.2 GW) and coal-fired (8.9 GW) power plants, according to our Preliminary Monthly Electric Generator Inventory.
The operation of hybrid plant, which can fire both coal and natural gas, has become increasingly more commonplace in recent years. There are several advantages for a power plant to be able to fire both coal and gas including greater fuel flexibility, less environmental emissions and increasing both the capability and efficiency of the plant.
Review of the operational flexibility and emissions of gas- and coal …
2018年2月1日 · Results show that gas-fired power plants are not only more efficient, but also faster and generally less polluting than coal-fired power plants. However, at their respective minimum complaint load, gas plants are less flexible and produced more NOx and CO emissions than coal-fired power plants.
Amber Schrum: Coal Versus Natural Gas in Power Plants
When the full life-cycle greenhouse gas emissions are analyzed, including the production and combustion emissions, the advantage of natural gas is maintained only when burned in modern and efficient power plants. A coal-fired power plant has a thermal efficiency on average of 33 percent, while a gas-fired plant ranges in efficiency from 40 to ...
