Coal and gas represent the main energy source for the Australian and many other national economies into the foreseeable future. The continuing use of these critical resources requires that greenhouse gas emission issues be addressed. Any serious attempt to achieve reduced emission of CO2 from power generation requires sequestration as a necessary element. A plausible method for cost effective sequestration of large amounts of CO2 is by geological fixing in deep, unminable coal. The key technological and scientific issues regarding capacity, rate, technical viability and site selection form the basis of this proposal.Read moreRead less
