The Hydrogen Risk Assessment Models (HyRAM) tool, developed by Sandia National Laboratories, is a widely used software platform for conducting quantitative risk assessment (QRA) of hydrogen systems. It integrates validated physical models, probabilistic data, and engineering methods to evaluate hazards associated with hydrogen production, storage, and refuelling infrastructure.
HyRAM enables users to simulate accident scenarios such as hydrogen leaks, jet fires, and explosions, and to assess their impact on people and infrastructure.
The tool supports the development of codes and standards, safety planning, and infrastructure design by providing a consistent and science-based framework for risk-informed decision making.
HyRAM was first introduced as a prototype around 2015–2016, with Version 1.0 released in 2016, and has since evolved into the more advanced HyRAM+ platform, which continues to be actively developed (latest versions 2023–2025).
This continuous development makes HyRAM a key digital tool supporting the safe deployment of hydrogen technologies worldwide.
