Safeguard High-Hazard Energy Projects with Specialist QRA Studies
As LNG, hydrogen, and green energy infrastructure continues to expand, facilities face unique process safety challenges that conventional hydrocarbon risk models cannot fully address. Cryogenic temperatures, high-pressure systems, hydrogen flammability, and emerging energy technologies require specialized risk assessment methodologies.
Aura Safety provides Quantitative Risk Assessment (QRA) services for LNG terminals, hydrogen facilities, renewable energy storage systems, and other major hazard installations. Our studies help organizations understand accident scenarios, evaluate risk levels, support regulatory compliance, and implement practical risk reduction measures throughout the project lifecycle.
Our QRA Services
Our specialists perform detailed, data-driven QRA studies that evaluate the likelihood and consequences of major accident events, including:
- LNG cryogenic releases
- Hydrogen leaks and jet fires
- Vapour cloud explosions
- Rapid Phase Transition (RPT)
- Cryogenic pool fires
- High-pressure storage failures
- Battery Energy Storage System (BESS) incidents
Using validated consequence modelling and probabilistic risk analysis, we calculate both individual and societal risk, helping demonstrate that facility risks are reduced to As Low As Reasonably Practicable (ALARP).
Our QRA studies also support:
- Facility siting and layout optimization
- Equipment spacing
- Emergency response planning
- Process safety decision-making
- FEED and detailed engineering
Why QRA is Critical for LNG & Hydrogen Facilities
Green energy facilities introduce hazards that differ significantly from conventional oil and gas operations.
Hydrogen
Hydrogen has a very low ignition energy, a wide flammability range, and can leak through extremely small openings. These characteristics require specialized modelling for leak dispersion, ignition probability, and explosion risk.
LNG
Stored at approximately −162°C, LNG releases can produce dense gas clouds, cryogenic effects, pool fires, and thermal radiation that must be accurately assessed.
Green Energy Systems
Electrolysers, hydrogen storage, ammonia production, methanol plants, and battery energy storage systems introduce new process safety challenges that require dedicated risk evaluation.
A facility-specific QRA helps identify hazards early, reduce project risks, and support safe, compliant operations.

Frequently Asked Questions
When should a QRA be conducted?
A QRA is most valuable during the Front-End Engineering Design (FEED) stage, allowing risk findings to influence facility layout and design. It should also be reviewed whenever significant process or operational changes occur, supported where appropriate by formal management of change reviews.
How is hydrogen QRA different from natural gas QRA?
Hydrogen requires specialized modelling due to its low ignition energy, wide flammability limits, rapid dispersion characteristics, and high-pressure storage systems.
Can QRA support regulatory approvals?
Yes. A QRA provides documented risk assessments that support environmental clearances, major hazard facility requirements, and other regulatory processes, depending on project requirements.
Can QRA assist with insurance evaluations?
Yes. Quantified risk information and ALARP demonstrations can provide valuable technical information during insurance risk assessments.
