Case Study · Design Intelligence
Decoding piston rings for oil-free hydrogen.
A global maker of polymeric seals needed best in class piston ring designs for oil-free hydrogen compressors. We combined patent analysis with in-depth expert interviews to uncover know-how the industry rarely shares.
The Client
The client is a leading global manufacturer of polymeric seals and engineered components for harsh applications. It wanted a design guideline for piston rings in oil-free, high-pressure hydrogen compressors.
The Challenge
Contain the molecule.
Stop the leak.
Hydrogen’s small molecular size makes it hard to compress and contain, demanding tight tolerances and designs tailored to each operating condition. Prescouter was asked to build a design guideline when much of the know-how is proprietary.
