A system includes a capture system, a storage system, and a return system. The capture system is configured to receive an outlet gas from a gasification system and to extract a component gas of the outlet gas using a regenerable material during a start-up operation of the gasification system. The storage system is coupled to the capture system and is configured to store the component gas extracted by the capture system. The return system is configured to return the component gas from the storage system to the gasification system during a normal operation of the gasification system.
