Presently the global warming by CO2 emission from fossil fuel burning is becoming a serious issue. Especially, coal is the worse fossil fuel, because it emits the largest amount of CO2 per unit amount of heat generation. There seem to be two ways of reducing substantial CO2 emission rate of coal; they are, reforming coal to synthesis fuel with less CO2 emission and removing CO2 from hue gas of coal fired power station after burning coal. Present paper proposes two nuclear heat application systems which reform coal to methanol and four systems which produce chemical products or gasoline with CO2 collected from Rue gas of coal fired power stations, as future options for reducing CO2 emission from coal. Advantage and disadvantage of the proposed systems are discussed.
