Systems and Methods for Producing and Using Hydrogen from Natural Gas in Mobile Applications
Applications of a natural gas reformer to mobile systems are described. A reformer with a plasma device is used to reform natural gas or light hydrocarbons to H2 and carbon. A vehicle includes the reformer, a natural gas reservoir, and a fuel cell. The fuel cell uses the H2 generated by the reformer to charge a battery in the vehicle or power an electric motor of the vehicle. Such systems are further used to distribute carbon, where carbon produced by the reformer is sorted to remove carbon black or nanostructure carbon, with each type of carbon compressed and or stored separately for use or commercialization. Such systems are further used to retrofit or otherwise reduce weight of electric vehicles (EV). Batteries installed in an EV are removed and replaced with a natural gas reservoir, reformer, and fuel cell, reducing the weight and improving efficiency of the EV.
1 . A method of powering a vehicle from natural gas, comprising:
supplying a feedstock to a reformer within the vehicle;
producing, by the reformer, hydrogen from the feedstock;
generating, by a fuel cell, electricity from the hydrogen; and
using the generated electricity to power an electric motor.
2 . The method of claim 1 , further comprising, after the step of generating electricity:
storing the electricity in a battery; and
wherein the step of using the generated electricity to power an electric motor further comprises:
supplying stored electricity from the battery to the electric motor and powering the electric motor with the supplied electricity.
3 . The method of claim 1 , further comprising storing the feedstock in a feedstock reservoir within the vehicle.
4 . The method of claim 1 , further comprising introducing the feedstock into the vehicle from an external source.
5 . The method of claim 1 , wherein the feedstock comprises natural gas or other light hydrocarbon.
6 . The method of claim 1 , further comprising pressurizing the feedstock prior to the step of supplying.
7 . The method of claim 1 , wherein the vehicle comprises a land vehicle, an aircraft, a marine vessel, or a spacecraft.
8 . The method of claim 1 , further comprising storing, in a container within the vehicle, a carbon byproduct generated by the reformer.
