The Renaissance of Coal?

Someday the fossil deposits in the earth will be exhausted; mankind is trying to delay this point in time with the aid of new technology. Newly developed processes are making coal extraction attractive again. New conveyor and transport techniques facilitate the mining of fossil fuel in places that years ago would have been too uneconomical to mine.
 
The development of new coal handling and transport technology seems advantageous for many power companies because the fossil is indeed an all-rounder – from it electricity can be generated, as well as fuels that compare favorably with kerosene, diesel and gasoline. Hence, the process of coal transformation is experiencing a comeback. In the face of increasing demands for power and insufficient alternative energy production, the return to coal seems to be the most satisfactory way to go, next to the controversial way of nuclear power.
 
In following this path, these new techniques bring both a blessing and a curse to the earth and its climate. The energy giant Vattenfall has announced that in the year 2008 the first “climate compatible” and “CO2-free” lignite power plant will go into operation. On the other hand, the production of fuel from liquefied coal is the number one energy killer, because through it the environment is doubly contaminated – liquid coal fuel emits CO2 in both the production and the combustion phases.
 
However, in view of increasing oil prices, coal fuel is of great interest to countries with huge coal deposits – the USA, India and China.
