Systems and methods for carbon capture

A system, comprising:

• an internal combustion engine comprising an intake and an exhaust, the intake being configured to receive an engine operating fluid comprising a mixture of air, natural gas, and reformed fuel, wherein the reformed fuel is provided by a hydrogen production module;
• a carbon capture device fluidly connected to the exhaust, the carbon capture device being configured to receive exhaust gas from the exhaust, and to remove carbon dioxide from the exhaust gas;
• and
• a hydrogen production module fluidly connected to the intake, and including a recirculation circuit having a reformer catalyst module, the hydrogen production module being configured to produce the reformed fuel by removing hydrogen gas from fluids in the recirculation circuit using the reformer catalyst module, the fluids comprising reformer natural gas, wherein:
• the hydrogen production module comprising a hydrogen control module configured to increase or decrease an amount of the hydrogen gas removed from the fluids to control a concentration of water vapor in the exhaust gas, wherein
• an increase in the hydrogen gas removed decreases an amount of hydrogen gas in the engine operating fluid, thereby decreasing the concentration of water vapor in the exhaust gas, and wherein
• a decrease in the hydrogen gas removed increases the amount of hydrogen gas in the engine operating fluid, thereby increasing the concentration of water vapor in the exhaust gas.
