Abstract

A system for producing hydrogen gas includes a first container, a microwave emitter configured to direct a microwave to the first container, a steam condenser, a second container and an effluent conduit. The first container includes a first container body configured to hold a quantity of water and aluminum particles inside. The steam condenser connects the first container with a first end of the effluent conduit. A second end of the effluent conduit can be inserted in the second container. The microwave emitter can be operated to direct a microwave to the water and aluminum particles (when the water aluminum particles are present inside of the first container). The radiation of the water and aluminum particles with the microwave will cause hydrogen gas to dissociate from the water. The hydrogen gas will travel through the steam condenser and the effluent conduit to be stored in the second container.

Dependent claims

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.

A method for producing hydrogen gas, the method comprising:

inserting a quantity of water in a container, wherein the container includes a container body having an opening, the container body defining an interior storage area accessible through the opening, the container body including a material configured to enable microwave radiation to pass therethrough;
inserting a quantity of aluminum particles within the water in the container body, wherein the aluminum particles have a size ranging from about 1 mm to about 10 mm;
irradiating the water in the container with a microwave for a period of time to produce a gas effluent, the gas effluent including hydrogen gas, wherein the microwave is generated by a microwave emitter, the microwave emitter being configured to direct the microwave to the interior storage area of the container body, the quantity of aluminum particles being a catalyst for a microwave dissociation reaction of the water;
condensing steam from the water with a steam condenser, the steam condenser having a first end in fluid communication with the opening of the 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, wherein an effluent conduit has 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;
and
collecting the produced gas effluent,
wherein the steam condenser is positioned above a surface of the water inside of the interior storage area.
