Threaded Modular Hydrogen Pressure Vessel for Large-Capacity Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current pressure vessels for high-pressure hydrogen gas have limited storage capacity, are difficult to produce and transport due to their size and weight, and require increased facility costs and inefficiencies when multiple vessels are installed.
Innovation Solution
A pressure vessel composed of multiple steel pipes or tubes connected by screw threads, allowing for easy assembly and disassembly, and enabling the vessel to be produced and transported in smaller, more manageable units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the outer diameter or length of each pressure vessel is increased to increase the capacity per pressure vessel, then the hydrogen gas storage capacity is improved, but the pressure vessel becomes difficult to produce and transport due to its size and weight
Solution Approach 1:
The pressure vessel is divided into multiple sections, each with a volume of 300 L or less, that can be connected in series. This segmentation allows each section to be easily produced and transported, while the overall storage capacity is increased by connecting multiple sections together to form a longer pressure vessel with total volume of 600 L or more.
2Quantity of substance
If the number of pressure vessels installed is increased to increase the hydrogen gas storage capacity, then the storage capacity is improved, but the facility cost increases and efficiency decreases
Solution Approach 1:
Multiple pressure vessel sections are connected in series to form a single integrated pressure vessel with total volume of 600 L or more. This merging approach reduces the number of separate vessels needed, thereby reducing the number of valves, support stands, and other components required, which lowers facility cost and improves operational efficiency.
3Quantity of substance
If a pressure vessel with large capacity is produced, then the hydrogen gas storage capacity is improved, but it becomes difficult to transport to the installation site requiring extensive operations
Solution Approach 1:
The pressure vessel is constructed from multiple sections that can be manufactured and transported separately to the installation site, where they are then connected in series. This segmentation enables transport of smaller, more manageable components without requiring extensive nighttime transportation operations or special transport vehicles.
