In the previous paper of this series, risks associated with potential hydrogen vapor cloud explosions were discussed, which is perhaps the most recognizable type of hydrogen hazard. However, hydrogen is stored and transported in high-pressure vessels and pipes, which represents additional inherent hazards. This paper focuses on the hazards of high-pressure hydrogen in application. The sudden release of high-pressure hydrogen gas represents several potential hazards and risks. An accidental failure could result in injuries to personnel nearby if fragments or projectiles are thrown from the failed vessel or pipe. The sudden release of high-pressure hydrogen gas could also cause a blast wave that could injure personnel. Secondary debris impacted by projectiles or blast waves can result in injuries as well. In addition, an accidental release of high-pressure hydrogen gas can result in damage to infrastructure and equipment in the vicinity. Learn more about what BakerRisk does to help mitigate the risk of high-pressure hydrogen gas hazards.
In previous articles in this series, BakerRisk discussed the hydrogen economy and high-level hazards. Additionally, best practices and general guidance for performing a PHA on hydrogen processing facilities to accurately assess all the risks and consequences associated with hydrogen were also covered. This article will focus on the materials and potential damage mechanisms and hazards associated with the operation of equipment exposed to hydrogen, including pressure vessels, pipelines, piping, and other equipment handling hydrogen.
Hydrogen has been used in petroleum refining, fertilizer production, chemical synthesis and many more applications for centuries. Throughout hydrogen’s use, releases have resulted in numerous explosion and fire incidents. Hydrogen is becoming more prevalent as a low carbon energy solution since it can be used both as an energy carrier as well as a replacement for raw materials. As hydrogen is adopted across more industries and applications, continued emphasis on preventing release and escalation is essential.
Test programs, such as those discussed above, have provided significant validation of the current methodologies used to analyze hydrogen hazards. Despite the enormous amount of work done by BakerRisk, the ERC, and others to understand the hazards associated with hydrogen, there is still more work to be done.
As the biofuels industry continues to expand in support of global decarbonization mandates and objectives, facility owners and developers are being challenged to balance production efficiency, operational reliability, and personnel safety.
The promise of hydrogen as the simplest of molecules and perhaps the most challenging and perplexing of energy carriers has the clean energy world diving into hydrogen applications across all major energy categories.
