Solution Overview

Problem

Stranded natural gas reserves, located in remote or difficult-to-access areas, pose significant challenges for utilization due to high transportation and conversion energy inefficiencies, economic costs, and environmental concerns, with current methods like liquefaction and gas-to-liquid conversion being inefficient and costly, and flaring being wasteful and economically unattractive.

Innovation Solution

Converting stranded natural gas into a high energy density material, such as boron or aluminum, through a reduction process using a material oxide, which is then transported to energy markets for energy generation, allowing for efficient energy distribution and monetization while reducing environmental impact.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If liquefaction is used to transport stranded natural gas, then transportation is enabled, but infrastructure cost increases

Engineering Contradiction:
Improvetransportation capabilityVSAvoidinfrastructure cost
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent changes the physical state parameter of natural gas from gaseous to solid by converting it into high-energy-density materials (hydrocarbons with API gravity greater than 30). This parameter change eliminates the need for complex liquefaction infrastructure while enabling transportation through existing liquid/solid handling systems.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces high-energy-density hydrocarbon materials as intermediary substances that convert stranded natural gas into a transportable form. These intermediaries (syncrude, diesel, jet fuel) serve as mediators between the remote gas source and market destinations, replacing the need for direct gas transportation infrastructure.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Quantity of substance

If gas-to-liquid conversion is used, then energy density improves, but conversion energy efficiency worsens

Engineering Contradiction:
Improveenergy densityVSAvoidconversion energy efficiency
Core Design Contradiction:
Quantity of substanceVSLoss of energy

Solution Approach 1:

The conversion process is made self-service by using the stranded natural gas itself as the energy source to power the conversion facilities. The gas is converted into high-energy-density materials that can then be transported and combusted, with the combustion energy potentially feeding back into the system, creating a self-sustaining energy loop that minimizes external energy inputs.

Inventive Principle:
Principle #25Self-service

3Ease of manufacture

If flaring is used to handle stranded natural gas, then economic cost is reduced, but energy waste increases

Engineering Contradiction:
Improveeconomic costVSAvoidenergy waste
Core Design Contradiction:
Ease of manufactureVSLoss of energy

Solution Approach 1:

The patent converts the previously harmful act of flaring (burning gas at wellheads) into a beneficial process by capturing the combustion energy and using it to power the conversion facilities. The stranded natural gas that would have been wasted is instead converted into valuable high-energy-density transportation fuels, transforming an energy loss into an energy gain.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

The present application is directed to a method and system for monetizing energy. More specifically, the invention is directed to the economically efficient utilization of remote or stranded natural gas resources. The invention includes importing a high energy density material into an energy market and distributing the high energy density material (HEDM) therein. The HEDM is produced from reduction of a material oxide such as boria into the HEDM, which may be boron. The reduction utilizes remote hydrocarbon resources such as stranded natural gas resources.
