A carbon capture system includes a hydrogen production module. The hydrogen production module is used to control the amount of hydrogen entering an internal combustion engine to reduce an amount of water vapor generated by the internal combustion engine, thereby increasing the efficiency of the carbon capture device. If too much water vapor is detected in an exhaust of the engine, the amount of hydrogen produced by a hydrogen production module can be increased, thereby reducing the amount of hydrogen entering the engine and reducing the amount of water vapor generated by the engine. A reformer catalyst can be used by the hydrogen production module to remove at least a portion of hydrogen in a fuel stream of the engine.
