A fossil fuel power plants convert energy of fossil fuel into electrical energy. The fossil fuel is burnt and the energy generated is used to heat the water in a boiler. Then the superheated steam is passed through the blades of the turbine to generate electrical energy. All the three types of fossil fuels are used for this purpose and they contribute to ~80% of the electrical energy generation.
As the fuel can generate bulk power they are being used for generation of the base load of the electric power demand. But, this source of electricity generation is not very green. When the fossil fuel is burnt they release the carbon, in the form of CO2. Also it releases nitrous oxide and sulfur oxide as a byproduct during its burning. When CO2 is known for its green house effects the other gases forms nitric, sulfuric and carbonic acids in rain and causes the infamous acid rain. Further to the same the fossil fuels does contain a certain amount of radioactive element which gets released to atmosphere when it is burnt. Amongst the three types, natural gas is the cleanest fuel and coal is the most polluting. Along with the aforesaid gasses it also releases several loose ash and other particulates which causes severe pollution to the atmosphere. To add to the above harmful effects the procedure is not very efficient causing a good amount of heat to escape.
Whatever may be the harmful effects, we cannot ignore this source of energy. So scientists have devised several solutions to reduce the harmful impacts. The Carbon Capture and Storage (CCS) technology is developed to capture to the extent off 85 – 90% of the CO2 before it is released to atmosphere. Similarly the Electrostatic Precipitator, Cyclone Collector or the Bag‐house is devised to arrest the particulates generated during the burning of coal.
With the advent of new technology, we can now look at biomass as a means to replace fossil fuel power plants. This white paper takes a look at how this is possible and the technologies involved in the same.
