Prosumer Gas Network Bypass for Bidirectional Gas Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers are unable to feed gas into the gas grid, leading to inefficiencies and potential climate-warming gas emissions, as storage facilities are limited and renewable energy production fluctuates.
Innovation Solution
A prosumer system with a bypass and meter configuration that allows gas to be fed into and extracted from the gas network, bypassing final pressure regulators and using intelligent meters to monitor and control gas flow and composition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If consumers can only store gas temporarily and then consume it themselves, then gas can be stored for later use, but the storage facility must be completely full before generation can be shut down or excess gas must be released into the atmosphere
Solution Approach 1:
The gas network acts as an intermediary storage medium between the prosumer's generation and consumption. Instead of requiring the prosumer's local storage facility to be completely full, excess gas can be temporarily stored in the gas network infrastructure and then consumed when needed, eliminating the need to shut down generation or release gas to atmosphere.
2Adaptability or versatility
If a bypass is designed to guide gas past the final pressure regulator into the gas network, then gas can be fed into the gas network, but the final pressure regulator cannot reduce the pressure of the gas in this mode
Solution Approach 1:
The system dynamically switches between different operational modes (introduction mode and acceptance mode) depending on whether gas is being fed into or extracted from the gas network. In introduction mode, the bypass is activated to guide gas past the final pressure regulator, while in acceptance mode, the final pressure regulator is activated to reduce pressure. This dynamic adaptation allows the system to handle bidirectional gas flow without requiring permanent complex pressure regulation infrastructure.
3Measurement precision
If intelligent meters are used to monitor and control gas flow, then gas flow and composition can be monitored, but the system complexity increases
Solution Approach 1:
Intelligent meters provide real-time feedback on gas flow quantity and composition to the control system. This feedback enables the control system to automatically adjust valve positions, pressure regulators, and other components to maintain optimal operating conditions, ensure accurate billing, and detect leaks or anomalies, thereby justifying the added complexity through improved measurement and control capabilities.
