Shared-Support Hydrogen Storage Assembly for Dual Pressure Levels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hydrogen storage assemblies require separate installations for different pressure levels, leading to labor-intensive construction and large ground area usage, as they cannot efficiently store pressurized hydrogen at varying pressures without requiring excessive space and resources.
Innovation Solution
A storage assembly design that incorporates a primary pressure vessel for lower pressure and a secondary pressure vessel for higher pressure, supported by a shared support, reducing the need for multiple installations and optimizing ground area usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If two separate storage assemblies are built for different pressure levels, then hydrogen can be stored at both 35 MPa and 70 MPa, but the construction becomes very labor intensive and requires a relatively large ground storage area
Solution Approach 1:
The patent combines two separate storage assemblies into one integrated structure. The first and second cylindrical pressure vessels are supported together by a shared support structure, merging what would traditionally be two separate installations. This reduces the number of individual supports needed and simplifies the overall construction while maintaining the ability to store hydrogen at both 35 MPa and 70 MPa.
Solution Approach 2:
The shared support structure serves multiple functions: it supports both the first pressure vessel (35 MPa) and the second pressure vessel (70 MPa), provides a common foundation for both storage assemblies, and reduces the overall footprint. This multi-functional design eliminates the need for separate support structures for each pressure level.
2Adaptability or versatility
If two separate storage assemblies are built for different pressure levels, then hydrogen can be stored at both 35 MPa and 70 MPa, but a relatively large ground storage area is required
Solution Approach 1:
By merging the support structures of two separate storage assemblies into one shared support system, the patent significantly reduces the ground area required. The shared support provides a common foundation that eliminates redundant structures, allowing the storage vessels to be positioned more closely together than would be possible with separate installations.
Solution Approach 2:
The patent utilizes vertical stacking by positioning the first and second cylindrical pressure vessels at different heights relative to the shared support. This three-dimensional arrangement allows both storage assemblies to coexist in a compact footprint, reducing the horizontal ground area while maintaining both pressure storage capabilities.
3Ease of manufacture
If separate support structures are used for each storage assembly, then each assembly can be independently constructed, but the construction becomes more labor intensive
Solution Approach 1:
The shared support structure consolidates multiple construction tasks into fewer individual works. Instead of constructing four separate supports (two for each storage assembly), only three supports are needed. This reduces the labor intensity and time required for construction while maintaining the ability to independently construct and commission each pressure vessel.
