It is the most abundant rank of coal, with deposits found around the world, often in rocks of Carboniferous age. Bituminous coal is formed from sub-bituminous coal that is buried deeply enough to be heated to 85 °C (185 °F) or higher. Bituminous coal is used primarily for electrical power generation [1] and in the steel industry.
The scale of the project transforming swathes of barren salt desert on the edge of western India into one of the most important sources of clean energy anywhere on the planet is so overwhelming ...
