The goal of this paper is to review hazard identification techniques available to evaluate the hazards and risks associated with a hydrogen system. In the previous paper of this series, an historical and future view of hydrogen was provided. This paper provides the reader with an overview of techniques used for evaluating the hazards of hydrogen production and consumption.
Mr. Gandhi is a member of BakerRisk’s Process Safety Group. He is a Process Safety Engineer with over 19 years of experience in controls and safety systems and over 12 years of experience in qualitative hazard and risk analysis. Mr. Gandhi manages Fire and Gas Systems (FGS) and Hazardous Area Classification (HAC) services at BakerRisk, where he has reviewed boilers and heater Burner Management Systems (BMS) to NFPA85 and NFPA86 standards.
Since 2020, he has led the Low Carbon Energy Risk Management group at BakerRisk which comprises of hydrogen and hydrogen carriers, biofuels, and Battery Energy Storage Systems (BESS) sub-groups. He has been a continuous member and leader of ISA at the student, local, and national levels since 2001 and the Hydrogen Technology Committee at CGA. He is the primary committee member for NFPA 715 Gas Detection Standard and is a contributing author on ISA TR84.00.07 Fire and Gas Detection and TR84.00.05 Burner Management System.
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.
