1. A system comprising:
a reformer configured to react methane with steam to produce a reformer product stream comprising carbon monoxide and hydrogen;
a combined cycle power generator fluidically coupled to the reformer, the combined cycle power generator comprising:
a steam turbine connected to a first end of a common shaft and configured to rotate the common shaft in response to receiving steam;
a gas turbine connected to a second end of the common shaft and configured to rotate the common shaft in response to receiving a mixture of fuel and air;
a power generator coupled to the common shaft, the power generator configured to convert rotational energy from the common shaft into electricity; and
a water boiler fluidically coupled to the steam turbine and configured generate steam in response to receiving heat; and
a switch that can adjust between a first position and a second position, wherein in the first position, the switch is configured to direct exhaust from the gas turbine to the reformer, and in the second position, the switch is configured to direct exhaust from the gas turbine to the water boiler; wherein the reformer is a part of an ammonia production system; the reformer comprises a reformer reactor and a second water boiler; the reformer reactor is configured to discharge the reformer product stream; the reformer product stream comprises methane; and the second water boiler is configured to generate steam in response to receiving the reformer product stream.
