SYSTEMS AND METHODS FOR PRODUCING HYDROGEN AND BYPRODUCTS FROM NATURAL GAS
Producing hydrogen and carbon from hydrocarbons in a single-step process is described. A feedstock including natural gas or other light (e.g., <C5) hydrocarbons is introduced to a plasma reformer. The plasma reformer typically includes a non-thermal plasma. The plasma separates hydrogen from the carbon of the feedstock, yielding H2 and carbon black. The carbon is separated from the H2, and the H2 is further used as fuel (e.g., generating electricity via fuel cell) either contemporaneously or at a later time, stored, pressurized, or dispensed to a vehicle. Excess electricity generated form the H2 is stored in a battery, and excess is either stored or pressurized. Carbon black is further condensed to reduce volume for storage or transport.
1 . A cost-effective method of producing H2 and carbon, comprising:
introducing a feedstock to a reformer;
using the reformer to concurrently separate H and C from the feedstock; and
separating produced H2 and carbon.
2 . The method of claim 1 , wherein the feedstock comprises natural gas or another hydrocarbon with no more than 5 carbon.
2 . The method of claim 1 , wherein the reformer uses a plasma.
3 . The method of claim 2 , wherein the plasma is a non-thermal plasma.
4 . The method of claim 1 , further comprising the step of storing the H2 and the carbon.
5 . The method of claim 1 , wherein a feedstock storage is distal to the reformer.
6 . The method of claim 1 , further comprising the step of conveying the H2 to a storage or a distribution point.
7 . The method of claim 6 , wherein the storage or distribution point is proximal to the reformer.
8 . The method of claim 1 , further comprising the step of pressurizing the produced H2.
9 . The method of claim 1 , further comprising the step of compressing the produced carbon.
10 . The method of claim 1 , wherein at least 20% of the carbon is in a nanostructure form.
11 . The method of claim 6 , wherein the H2 is dispensed to a vehicle.
12 . The method of claim 11 , wherein the vehicle is one of a California DMV class vehicle, a locomotive, a propeller vehicle, a turbine vehicle, a sea craft, or a construction vehicle.
13 . The method of claim 1 , wherein a portion of the H2 is used by a fuel cell to produce electricity.
14 . The method of claim 13 , wherein the electricity is used to power at least one of the reformer, a step of storing the H2 or carbon, a step of condensing the H2 or carbon, or a step of dispensing the H2.
15 . The method of claim 1 , further comprising a step of providing H2 for use as a fuel contemporaneous to separating the produced H2.
16 . The method of claim 15 , wherein the H2 is used as a fuel in proximity to production of the H2.
17 . The method of claim 15 , further comprising a step of altering a rate of production of H2 according to a demand for electricity derived from the fuel.
18 . The method of claim 17 , wherein the electricity demand is from one of an electricity grid, an electricity storage capacity, an electrically operated device, an electronic system, or a plasma device.
19 . The method of claim 15 , further comprising the step of using the fuel to generate electricity, and storing unused electricity in a battery.
20 . The method of claim 15 , further comprising the step of storing excess fuel in a pressurized tank.
21 . The method of claim 15 , further comprising using a fuel cell to convert and store excess fuel as electricity.
22 . The method of claim 1 , wherein the method is localized to one of a building or a vehicle.
23 . The method of claim 22 , wherein the building is one of commercial, residential, industrial, or utility.
