The rest was produced under 'captive' mining licences for individual industrial use. Coal from the new mining licences, however, can be sold on the open market. Modi has said India will spend INR500bn ( billion) "for creating infrastructures around coal mining," adding the country was targeting gasification of 100mt of coal by 2030.

Out of India's 173 power plants presently, 100 plants have critical level of coal stockpile. India currently generates over 75% of its power through thermal coal. India has repeatedly iterated plans to achieve domestic coal production of over 1 billion mt by 202324 with coal blocks being auctioned to private companies to boost domestic production.

It also has health benefits due mainly to the lower quantity of coal burned per energy generated as well as to small reductions in the sulfur content of coal burned. Cropper's study in fact estimates that washing coal could reduce the number of deaths by 20% per power plant. Currently only 4% of coal in India is washed, and this offers an ...

Both fossil and renewable fuel sources are used widely to produce electricity around the globe. The dependency on fossil fuels for energy leads to the depletion of reserves and various forms of pollution. Coal fly ash (CFA) is one of the most burning issues in the whole world due to its large amount of production in thermal power plants. Every year a million tons (MTs) of CFA are generated ...

So, in summary it can be said that gasificationbased power offers efficiency benefits in the use of water. Raw water use in IGCC plants is lower than in pulverized coal plants. Without CCS, PC plants have a much higher steam turbine output, requiring more cooling water and condenser duties (typical raw water use ratio of :).

Coal oil was used primarily as fuel for streetlights and other illumination. The widespread use of kerosene reduced the use of coal oil in the 20th century. Coking coal is used in largescale industrial processes. The coal is coked, a process of heating the rock in the absense of oxygen. This reduces the moisture content and makes it a more ...
