Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current low carbon intensity energy strategies face challenges in reducing greenhouse gas emissions throughout the lifecycle of transportation fuels and hydrogen production, including inefficiencies in energy transmission, high carbon intensity in fuel production and transportation, and the need for specialized infrastructure and equipment, which can negate environmental benefits.
Innovation Solution
Implementing systems and methods that integrate renewable energy sources into feedstock procurement, transportation, refining, and distribution processes to reduce carbon emissions, using techniques such as power generation from wind, solar, and geothermal energy, and blending with plant-derived ethanol and biodiesel, while optimizing refinery processes and transportation modes to maintain low carbon intensity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If renewable energy sources are integrated into feedstock procurement, transportation, refining, and distribution processes, then carbon emissions are reduced, but system complexity and infrastructure requirements increase
Solution Approach 1:
The patent combines multiple renewable energy sources (wind, solar, geothermal) and integrates them across the entire fuel production lifecycle from feedstock procurement through distribution. This merging approach consolidates various low-carbon technologies into a unified system that reduces overall carbon emissions while managing complexity through integrated design
Solution Approach 2:
The system employs multi-functional infrastructure that can handle both conventional and renewable energy inputs, as well as multiple feedstock types. The refining and distribution infrastructure is designed to be versatile, accommodating different low-carbon fuel pathways without requiring completely separate specialized systems for each function
2Object-generated harmful factors
If specialized infrastructure and equipment are deployed for renewable energy integration, then environmental benefits are achieved, but cost and implementation difficulty increase
Solution Approach 1:
The patent employs dynamic system design where the mix of renewable energy sources and feedstock types can be adjusted based on availability, cost, and environmental priorities. The system can adaptively switch between different low-carbon pathways (wind-powered transportation, solar-refined fuels, geothermal-processing) rather than being locked into a single rigid infrastructure configuration
Solution Approach 2:
The system utilizes parameter changes in the form of varying operational conditions for different renewable energy inputs. By adjusting operational parameters (temperature, pressure, processing conditions) based on the specific renewable energy source being utilized, the infrastructure can efficiently handle diverse low-carbon inputs without requiring fundamentally different equipment for each energy type
3Ease of operation
If conventional fuels are used in traditional retail outlets, then consumer accessibility is maintained, but carbon intensity remains high
Solution Approach 1:
The patent introduces low-carbon intermediaries in the form of renewable energy-powered transportation and processing steps between the consumer and the fuel combustion. Even though the end consumer uses conventional fuel infrastructure, intermediary processes (electric vehicle transportation of feedstock, renewable-powered refining) mediate to reduce the overall carbon intensity of the fuel delivered to traditional retail outlets

AI summary
Systems and methods to provide low carbon intensity (CI) transportation fuels through one or more targeted reductions of carbon emissions based upon an analysis of carbon emissions associated with a combination of various options for feedstock procurement, feedstock refining, processing, or transformation, and fuel product distribution pathways to end users. Such options are selected to maintain the total CI (carbon emissions per unit energy) of the transportation fuel below a pre-selected threshold that defines an upper limit of CI for the transportation fuel.
