They started building gas plants next to existing plants many years ago. They were called peaking plants. Perhaps coal plants will be called peaking plants and the gas will carry the load.
Here is a simple chemistry lesson for all. Carbon(which is in coal) is 12, oxygen is 16 but oxygen is diatomic so O2 is 32 and CO2 is 44 atomic mass units. Well it works the same if we are talking about tons. 12 tons of carbon needs 32 tons of oxygen to burn making 44 tons of CO2. A guy that worked in the control room of the Cayuga power plant said they could go through a 50 ton car load of coal in 12-15 minutes. So say out of the 50 ton of coal there is 36 ton of carbon. Even though there may not be 14 tons of ash, water, sulfur and other things. That said, 36 ton of carbon will need 96 ton of oxygen and make 132 ton of CO2 in about 15 minutes.
There was a trail with 100 cars of coal that went through Terre Haute every day headed to just that one power plant in Indiana. About half the states rely on coal based electricity.
I don't think there are too many people who can wrap their head around just how much CO2 is generated each day making electricity in this country. You would have to learn how to use a scientific calculator and the number would be too large for most of us to comprehend.
