Our expertise and services help hydrogen facilities improve siting and meet regulations
We have a depth of experience supporting regulatory compliance for hydrogen projects. This ranges from reviews of fire codes to application of NFPA 2 to interfacing with regulatory authorities. Our experience has helped projects navigate through regulatory challenges such as fueling station siting and hydrogen system fire protection.
Our consequence analysis services have proven invaluable to many hydrogen projects. Through the use of CANARY by Quest, consequence modeling software, we can describe and quantify hazard scenarios. Many codes and standards allow performance-based studies to describe the potential impacts, in some cases this allows projects to deviate from the prescriptive regulations. These services have been successfully applied to pipelines, refineries, fueling stations and storage systems.
Risk quantification may be provided in addition to code compliance and consequence analysis. A quantitative risk analysis (QRA) allows the probabilistic factors to be combined with the consequence analysis to present risk results. Quest has applied QRA to hydrogen projects to calculate risk to people, equipment and building occupants.
Safety and siting evaluations for hydrogen fueling stations: 2020/2021, California.
Facilitated a process hazard analysis (PHA) for each station to evaluate inherent hazards of the system, and evaluated the siting and layout of each station, based on NFPA 2 requirements. Where spacing did not meet the prescriptive siting in NFPA 2, a performance-based analysis was performed. Quest contributed crucial feedback during the design phase to help the project achieve code compliance and improved safety.
QRA for hydrogen systems addition to a natural gas compression station: 2021, California.
Performed a detailed consequence analysis and frequency analysis on hydrogen and natural gas systems in order to evaluate risk to people and equipment. Quest presented the people and equipment risks and provided a risk assessment with recommendations for risk mitigation, to allow the project to focus resources on the mitigation of high-risk areas.
Siting and code compliance for hydrogen fuel-cell vehicle repair: 2021, multiple US locations.
Reviewed the applicability of codes and standards to each facility within the local jurisdiction. Quest provided guidance on code compliance in order to allow repair and service of hydrogen-powered vehicles, with considerations for applicable repairs and fuel venting.
Siting of occupied buildings in a refinery with a hydrogen production unit: 2020, California.
Modeled and evaluated hazards due to hydrogen production and distribution within the refinery. Quest provided consequence modeling results for the hydrogen hazards and made recommendations for siting of occupied buildings.
Building siting study for a flare testing facility: 2015-2020, Oklahoma.
Evaluated and modeled hazards from multiple systems, including a proposed a liquid hydrogen storage system. Recommended potential locations for the hydrogen system based on the hazards and the locating of existing occupied buildings. Quest helped the facility achieve a safer layout that met the guidelines through consequence modeling and hazard evaluation.
QRA for hydrogen-powered bus refueling systems: 2008, California.
Quest conducted a QRA for a refueling system in a suburban area intended for public transport buses. The location of the hydrogen systems was evaluated and assessed with a risk-based process. Quest helped to show that the design of the facility did not adversely impact the public or operating personnel.
Consequence modeling for a hydrogen pipeline: 2006, California.
Quest provided modeling calculations for potential releases from a proposed hydrogen pipeline, which were compared to an existing natural gas pipeline. The results allowed the project to meet California regulations.
Comparative QRA for hydrogen reactor options: 1995.
Analyzed the consequences and frequencies two hydrogenation reactors. The resulting risk was then compared and discussed. Quest provided a way to compare the safety risks from the two hydrogen reactor options through expertise is consequence and frequency analysis.
