Concept of solar-hydrogen-methanol energy system for the transportation sector in Japan is outlined. In the system, methanol is produced with CO<SUB>2</SUB> recycled and H<SUB>2</SUB> produced by electrolysis with photovoltaic power.<BR>Concerning CO<SUB>2</SUB> recovery from the exhaust gas of a 10, 000 kW diesel engine to be used in the methanol energy system, the effects of CO<SUB>2</SUB> recovery parameters such as gas and liquid flow rates, liquid concentration, and stripping temperature on the engine performance and the attainable CO<SUB>2</SUB> recovery ratio are analyzed on the basis of a mass transfer calculation model for a packed column with aqueous monoethanolamine solution. Heat rejected from the engine is used for CO<SUB>2</SUB> recovery, but reduction in the engine output power is not avoidable, which is mainly caused by the shortage in power of turbocharger and the supplemental supercharging power. Both the maximum attainable CO<SUB>2</SUB> recovery ratio and the reduction in the engine output power depend on the ratio of the stripping steam feed rate to the flow rate of the exhaust gas.
