Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current subsurface storage systems for high-pressure gases face challenges in efficient installation, servicing, and remediation due to complex configurations and the need for concrete backfilling to secure storage containers.
Innovation Solution
A subsurface storage pod system featuring a pod hanger support plate with upper and lower plates, interlocking support flanges, and annular bushings to secure and support storage containers, allowing for individual container replacement and removal without concrete backfilling, and incorporating ventilation channels for gas flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If storage containers are cemented into place with concrete backfilling, then storage container stability is improved, but installation complexity and remediation difficulty increase
Solution Approach 1:
The support system is divided into modular components including a support plate with multiple support structures, each independently configurable to hold storage containers. This segmentation allows for easier installation and removal compared to monolithic concrete backfilling, as each support structure can be independently adjusted or removed without affecting the entire system.
Solution Approach 2:
The support structures are designed with adjustable and reconfigurable features, allowing the system to adapt to different installation scenarios and container configurations. This dynamic capability enables simpler installation and remediation processes compared to fixed concrete structures, as the support system can be modified or removed as needed without permanent site modification.
2Stability of the object's composition
If complex configurations are used to secure storage containers, then storage container stability is improved, but servicing efficiency decreases
Solution Approach 1:
The support plate incorporates multiple discrete support structures that can independently secure individual storage containers or groups of containers. This segmentation enables selective access and servicing of specific containers without requiring modification of the entire support system, thereby improving servicing efficiency while maintaining stability.
Solution Approach 2:
The support structures are designed to be removable and reconfigurable, allowing for easy removal and replacement of storage containers during servicing operations. This design enables efficient container exchange without permanent fixtures, improving productivity during maintenance and remediation activities.
3Productivity
If individual container replacement is enabled, then servicing efficiency is improved, but support structure complexity increases
Solution Approach 1:
The support plate is designed with modular support structures that can be independently configured and removed. Each support structure is a self-contained unit that can hold one or more storage containers, allowing for individual container replacement without affecting other parts of the system. This modular approach enables efficient servicing while keeping each individual support component relatively simple in design.

AI summary
Apparatus for the subsurface storage of one or more pressurized gases such as hydrogen, compressed natural gas, etc. A subsurface storage pod includes a pod hanger support plate configured to span an opening of a well bore that extends into a subsurface formation. The support plate includes an upper plate with storage container apertures extending therethrough, a lower plate configured to be supported by a support pad that surrounds the well bore opening, and at least one support flange that extends between and interconnects the upper and lower plates. Gas storage containers extend through the storage container apertures and into the well bore. A vent aperture allows flow of gases from within the well bore to the surrounding environment. The support flanges may be arranged as interlocking members in a crossing pattern, and the lower plate can be arranged as discontinuous segments installed between adjacent pairs of the interlocking members.
