1. A system configured to produce hydrogen gas, the system comprising:
a first container, the first container including a first container body having a first opening, the first container body defining a first interior storage area accessible through the first opening, the first container body including a material configured to enable microwave radiation to pass therethrough, wherein the first container body holds a quantity of liquid inside, wherein the liquid comprises water;
a quantity of aluminum particles received within the quantity of liquid in the first interior storage area of the first container body, wherein the aluminum particles have a size ranging from about 1 mm to about 10 mm;
a microwave emitter configured to direct a microwave to the first interior storage area;
a steam condenser having a first end in fluid communication with the first opening of the first container body, a second end opposite to the first end thereof, and an elongated steam condenser body extending between the first and second ends thereof; and
an effluent conduit having a first conduit end in fluid communication with the second end of the steam condenser, a second conduit end opposite to the first conduit end, and an elongated effluent conduit body extending between the first and second conduit ends,
wherein, when the first interior storage area of the first container contains the quantity of liquid inside, the microwave emitter is configured to direct the microwave to the first interior storage area such that the microwave can travel through the first container body and through the liquid inside of the first interior storage area to cause the hydrogen gas to be emitted from the liquid, the quantity of aluminum particles being a catalyst for a microwave dissociation reaction of the water, and
wherein the steam condenser is positioned above a surface of the water inside of the first interior storage area.
