Fossil Fuel Power Summary
Fossil Fuel Power Summary - Part 1
While fossil fuels are an abundant source of energy, their distribution between countries varies widely. Gas and coal based power generation contribute approximately than 23% and 36% respectively to the world's electricity production.
- Fossil fuel based power systems contribute approximately 60% of the worlds power.
- While fossil fuels are an abundant source of energy, coal and natural gas distribution between countries varies widely - in quality, quantity and extractability.
- There are three primary classes of coal based power generation technologies.
1) Pulverised Fuel (the most common)
2) Circulating fluidised bed combustion
3) Gasification - While there are two classes of natural gas fired power - gas turbines are the most common in the power industry. Industrial frame turbines are use for stationary power generation. They are suited for both open and combined cycle operation and peaking, intermediate and base load applications.

While control technologies do exist for most greenhouse and non-green house gas emissions,
implementation remains an environmental challenge for fossil fuel plants.
- While emission control technologies exist for most greenhouse and non-green house gas emissions, they still remain an operational, cost and environmental challenge from fossil fuel plants.
- Open cycle capital costs are mostly the combination of the gas turbine and balance of plant costs. The combined cycle costs are dominated by heat recovery steam generator at nearly 60% of costs.
- For conventional coal fired power plants, the turbine and boilers make up less than 15% of the overall capital cost of a plant.
- The gasifier and balance of plant (including cooling) is more than 60% of the capital cost of a gasification based power plant.
