When can the killer treasure a betting knight? Three major problems of using coal as a energy source:
- Lot of ash generated causing disposal problems and occupational health hazards to the workers.
- Sulphur dioxide emissions.
- Carbon dioxide emissions contributing to green house effect.
Clean Coal technology is a developmental technology aimed tackling the above mentioned problems. It uses the technology available to reduce generation of carbon dioxide and removal of sulfur dioxide generated from burning the coal while producing power. The coal is prewashed so as to reduce the amount of ash produced. The resulting carbon dioxide gas is trapped in deep logical formations like abandoned coal mines oil wells and in saline formation or in the sea. These technologies have their own negatives and positives and are not proven on an industrial scale. But still it is an attempt to address the concern of the global warming due to the carbon dioxide emissions. Clean coal technology is still at the nascent stage but we cannot do without coal which is the cheapest and most abundantly available fossil fuel.
