Among the alternatives CO2 storage in geological media has significant advantages. Experience and sophistication gained in mining and oil industry is a readily available infrastructure of knowledge, techniques and understanding. All the available methods may apply with a reasonable cost since terrestrial storage areas can be used by inland and seaside locations of emissions. However, it must be stated that available methods of geological storage, still, need elaborate researches. Since the global emissions of CO2 is expected to rise, depending on the industrial development and increase of population. Pessimistic approaches project at approximately 150 years for live of coal and the shorter lives for others. Therefore, in addition to researches for the newer and safer energy resources, enhancing the geological storage methods of CO2 need to be paid more effort, since it is the only available method which can be applied to eliminate significant amounts of CO2.
