of the total cost of electricity produced, a coal plant is the cheapest, and a gas red plant comes just after, because gas is more expensive to produce, transport, and store, even though it is the most efcient among all other types of power plants. In the following, we discuss the power generation process of these different
One of the main energy sources utilized to produce power is coal.

A fossil fuel power station is a thermal power station which burns a fossil fuel, such as coal or natural gas, to produce fuel power stations have machinery to convert the heat energy of combustion into mechanical energy, which then operates an electrical prime mover may be a steam turbine, a gas turbine or, in small plants, a reciprocating gas engine.
Flue gases, bottom ash, and fly ash formed during fuel combustion are examples of pollution occurring from the combustion process. Land use of the power plant, coal mining and transport, and feeding of the coal to the combustion chambers can also cause pollution. The cooling water is another pollution source to the surrounding water systems.

Cogeneration Process. Generally, the cogeneration process is the generation of heat energy and power in one system using a single energy resource, which often yields considerable reductions in input energy rate compared to separate systems [25]. From: Comprehensive Energy Systems, 2018. View all Topics.
An integrated gasification combined cycle (IGCC) is a technology using a high pressure gasifier to turn coal and other carbon based fuels into pressurized gas—synthesis gas ().It can then remove impurities from the syngas prior to the electricity generation cycle. Some of these pollutants, such as sulfur, can be turned into reusable byproducts through the Claus process.
Despite the historical tightening of emission constraints from coalfired power plants, its use for power generation has been on the increase mainly due to its availability, cost and the ever increasing global energy demand [2], [3], [4]. This shows that coal will continuously play a major role in meeting the global energy need.
Even before the outbreak of COVID19, fossilfuel power plants faced significant disruption from renewable energy sources, low gas prices, and ambitious decarbonization goals, all of which are changing customer preferences. Now, as the powergeneration industry shifts to the next normal, adopting the latest digital and advancedanalytics technologies has become critical.
