Hydrogen fuel is being considered for rail transport applications. As a new technology, it poses risks. We propose to integrate System-Theoretic Process Analysis (STPA) with Structural Causal Models (SCMs) to analyze the risks of new technology systems. The integration allows leveraging the STPA capability of identifying hazardous scenarios for a system, also due to the socio-technical environment in which the system is operated, and the SCM capability of assisting experts in the understanding of risks and in their evaluation. The integration provides a flexible framework that is here applied for the analysis of the hazards and risks emerging from the introduction of hydrogen as a fuel for the rail industry.

Abstract
Hydrogen fuel is being considered for rail transport applications. As a new technology, it poses risks. We propose to integrate System-Theoretic Process Analysis (STPA) with Structural Causal Models (SCMs) to analyze the risks of new technology systems. The integration allows leveraging the STPA capability of identifying hazardous scenarios for a system, also due to the socio-technical environment in which the system is operated, and the SCM capability of assisting experts in the understanding of risks and in their evaluation. The integration provides a flexible framework that is here applied for the analysis of the hazards and risks emerging from the introduction of hydrogen as a fuel for the rail industry.| File | Dimensione | Formato | |
