Evaluating Elastomer Resilience to Hydrogen for O-Ring Applications in Rapid Gas Decompression Environments

Abstract

The development of high-pressure hydrogen storage and distribution systems necessitates reliable polymeric materials that can withstand exposure to these demanding conditions. These systems utilize various components, including pressure vessels, pipelines, and fuel cell systems, each requiring specific polymeric materials with tailored properties. One critical challenge in this domain is ensuring the integrity of seals, particularly O-rings, exposed to high-pressure hydrogen gas. Rapid Gas Decompression (RGD), also known as Explosive Decompression (XDF), poses a significant threat to the performance and lifespan of these seals. This introduction explores the role of polymeric materials in high-pressure hydrogen applications and delves into the phenomenon of RGD-induced damage in elastomeric O-rings.
