Sorry. Natural Gas Liquids. Some combination of methane, ethane, isobutane, and propane, which are compressed/chilled to a liquid state for transportation and used to power electric generators.

Natural Gas Liquids. I remember seeing Liquid Natural Gas quite a bit, but I guess we can just shuffle the letters around however we want.

Edit: If you want to know the difference (more details here)

What Is Liquefied Natural Gas (LNG)?

Liquefied Natural Gas is natural gas that has been cooled to approximately -162 degrees Celsius. At this temperature, methane—the primary component of natural gas—transforms into a liquid. The process reduces the volume of the gas by about 600 times, making it easier to store and transport over long distances.

What Are Natural Gas Liquids (NGLs)?

Natural Gas Liquids are a group of hydrocarbons found in natural gas and crude oil. They are extracted as part of natural gas processing or crude oil refining. NGLs include ethane, propane, butane, isobutane, and natural gasoline. Unlike LNG, which is predominantly methane, NGLs are heavier hydrocarbons with distinct chemical and physical properties.

Natural gas turbines can bypass the need to boil water and drive steam turbines, because the actual combustion of the gas creates the rotational energy directly.

Steam turbines are pretty great, though. Not sure how the rest of a coal plant operates, but the turbines themselves shouldn't be touching any combustion byproduct.
