Large-Scale Electrolysis Plant Design and Emerging Safety Considerations, an EPC’s Perspective

Black & Veatch is currently designing and constructing large-scale electrolysis plants throughout the U.S. Building first-of-a-kind electrolysis facilities at scale requires the proper balance of minimizing costs while maximizing safety. Gaps and inconsistencies in codes such as NFPA 2 and CGA require EPCs to perform additional due diligence when incorporating safety by design principles. This talk will discuss Black & Veatch’s experience with safety by design in its projects, including equipment spacing requirements, hydrogen detection considerations, venting vs. flaring, the production of ammonia as an energy carrier with additional safety considerations, implications of hourly load following on electrolyzer selection and design, and other subjects.

This presentation will also describe best practices when discussing hydrogen and associated safety requirements with clients and the public to minimize misinformation about hydrogen. The presentation aims to provide a starting point for discussion between all stakeholders in the hydrogen economy to understand how to best design and implement safety by design in all large-scale electrolysis projects. The safe production of large-scale hydrogen is imperative to increase public confidence and build industry trust, both of which are required for scaling these projects.
