Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If serpentine configured steel pipe systems are used for storage, then storage capacity is provided, but corrosion and leaks occur reducing reliability
Solution Approach 1:
The patent employs multi-layer composite tubing structures combining different materials (e.g., polymer liners, metallic reinforcement layers, protective coatings) to achieve both corrosion resistance and structural integrity. The composite construction allows the system to maintain reliability while providing adequate storage capacity for hydrogen and hydrocarbon media.
2Ease of operation
If above ground pipelines are used for storage, then access and monitoring are improved, but security risk and public safety concerns increase
Solution Approach 1:
The patent utilizes underground installation of the coiled tube structures within protective encasements or buried configurations, nesting the storage system within the ground infrastructure. This approach maintains monitoring capabilities while reducing security risks and public safety concerns associated with above-ground pipelines.
3Quantity of substance
If underground rock bearing storage is used, then large volume storage is achieved, but permeation losses increase especially for hydrogen
Solution Approach 1:
The patent employs specialized composite materials with low permeability characteristics, particularly for hydrogen storage applications. The multi-layer construction includes barrier layers designed to minimize gas permeation while maintaining structural integrity for large volume underground storage.
4Quantity of substance
If tube trailers are used for localized storage, then mobile storage capacity is provided, but transportation costs and emissions increase
Solution Approach 1:
The patent enables storage facilities to be pre-installed at locations near production or consumption points, eliminating the need for continuous transportation of storage containers. The coiled tube structures can be installed directly at hydrogen production facilities or refueling stations, providing localized storage that reduces transportation requirements.
5Ease of manufacture
If traditional manufacturing and installation methods are used, then construction is completed, but carbon emissions and transportation costs increase
Solution Approach 1:
The patent utilizes modular coiled tube sections that can be manufactured separately and assembled in place, reducing the need for extensive material transportation. The segmented approach allows for localized manufacturing and reduces the carbon footprint associated with transporting large quantities of piping materials to remote installation sites.
