Ehrhart, Brian D.; Hecht, Ethan S.; Devin, Michael C.; Groth, Katrina M.; Reynolds, John T.; Blaylock, Myra L.; Carrier, Erin E.; Schroeder, Benjamin B.

The HyRAM+ software is an open-source toolkit that provides publicly available models and default input values to enable straightforward and consistent safety assessments for hydrogen and other alternative fuel systems, such as natural gas and propane. The HyRAM+ quantitative risk assessment calculation incorporates annual likelihood of leaks or failures for both compressed gaseous and liquefied flammable fuels, as well as probabilistic models for the effects of heat flux and overpressure.
