Hydrogen Combustion Risk Analysis (HCRA).

WHA’s formal hydrogen risk analysis tool leads the industry in analyzing hydrogen fire and explosion risk for both systems and components.

Are your systems and components safe for use with Hydrogen?

As the hydrogen economy grows, industry standards and guidelines have quickly become outdated or difficult to navigate. For many new applications, hydrogen-specific standards do not yet exist, and industry is dependent on risk analysis to avoid hydrogen combustion events. WHA International is paving the way to help ensure a safe future for everyone involved with hydrogen.

Your Hydrogen Safety Experts.

For over 30 years, WHA International has helped industries around the world understand and mitigate the risks associated with oxygen, hydrogen, and other hazardous fluids. Based on our experience and knowledge of established methodologies, we’ve developed a Hydrogen Combustion Risk Analysis (HCRA) method, customized to the unique hazards of hydrogen today.

Hydrogen Combustion Risk Analysis Types.

Our risk analysis solutions can be applied to both components and systems utilizing hydrogen or hydrogen blends.

System-Level

Analyzes the overall risks and relationships between components and subsystems within a hydrogen system. Considers design as well as operational and administrative controls.

Component-Level

Analyzes the parts, materials, and overall risks within components intended for use in hydrogen systems.

Hydrogen Combustion Risk Analysis Levels.

We offer combustion risk analyses at several different levels, depending on the level of detail you need.

Level 1: HHC

Hydrogen Hazard Consult

High-level review intended to provide rapid feedback. Typically appropriate for verbal remote review.

Level 2: HHR

Hydrogen Hazards Review

Same approach as a Level 1, but includes a short summary report documenting the results.

Level 3: HCRA

Hydrogen Combustion Risk Analysis

Our most extensive hazards analysis for hydrogen systems and components, including detailed probability rankings and recommended hazards mitigation strategies.

The HCRA Approach.

Our hydrogen risk analysis approach  sets the bar for industry, providing technical risk analysis for your unique installation and operating conditions. The approach analyzes the probability of operations and failure modes that can lead to combustible mixtures and ignition events resulting in fire, deflagration, or detonation. It also considers the consequences of combustion as they relate to personnel safety, system objectives, and functional capability. Our analysis may be supported by quantitative data, modeling, and/or custom testing.

Services include:

  • System documentation and component information review
  • System-level hazard analysis
  • Design review (overall system design and relationships between subsystems and components)
  • Administrative controls review (operating, maintenance, emergency, and training procedures)
  • Material compatibility analysis
  • Combustion consequence and secondary effects analysis
  • Component analysis
