Authors have discussed the possibility of fluidising coal, either into gases such as methane or other higher hydrocarbons in liquid form using bacteria. Methanogenic bacteria has been suggested as a possibility; however adaptation of methanogenic bacteria or other microorganisms for converting solid coal to liquid or gas may lead to pumping of these fluids from bore holes. Consequently conventional mining involving hazards, such as fire, explosion, poisonous gases, roof falls and other manmade risks such as run away of tubs, etc. may be avoided. Two distinct possibilities of using these gases have been suggested. One utilising gas fired thermal power pants or alternatively for storing them in cylinders or transportation through pipe lines is a distinct possibility. The other possibility, that is generation of power directly as fuel cell has also been critically examined. Use of photosynthetic bacteria along with adapted methanogenic bacteria, thereby utilising coal for cell formation and solar energy as source of energy for bacterial growth has been suggested for better environmental and ecological balance. Authors have also compared merits and demerits of suggested technology with underground coal gasification.
