Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wind turbines face challenges in providing alternative power outputs and efficient integration of electrolysis systems, particularly due to the need for flexible power conversion and modular assembly for service and transportation.
Innovation Solution
A wind turbine design comprising at least two separate units, one housing a rotor-supporting assembly and the other an electrolysis cell stack, allowing for modular assembly and disassembly, with units resembling shipping freight containers for ease of handling and integration of power conversion systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electrolysis cell stack is integrated into the nacelle with the rotor-support assembly, then the power conversion system is compact, but the system becomes difficult to service, replace, and transport
Solution Approach 1:
The wind turbine system is divided into separate modular units: the nacelle containing the rotor-support assembly and generator, and the electrolysis cell stack housed in a separate container. This segmentation allows independent servicing, replacement, and transportation of each module without affecting the other components, directly resolving the serviceability issue while maintaining power conversion functionality.
2Productivity
If the electrolysis system is built as a custom integrated structure, then it is optimized for specific functions, but transportation and handling costs increase
Solution Approach 1:
The electrolysis cell stack is housed in a standardized shipping container that serves multiple functions: it protects the electrolysis system, provides a standardized transportation unit, offers modular assembly capability, and can be stacked or positioned flexibly. This universal container approach enables the system to maintain optimized chemical production functionality while dramatically reducing transportation and handling costs through standardization.
3Ease of operation
If the electrolysis cell stack is placed in a separate container, then transportation and service become easier, but the integration complexity between units increases
Solution Approach 1:
The separate electrolysis container and nacelle are connected through integrated power and fluid connection systems. The generator in the nacelle directly powers the electrolysis cell stack in the separate container, and fluid pathways are established for water supply and hydrogen output. This merging of power and fluid systems across the modular boundary enables easy handling and transportation of separate units while maintaining functional integration through standardized connection interfaces.
