WP3 – Hydrogen jet fires effects

WP3 – Thermal and pressure effects of hydrogen jet fires and structure integrity

The research pillar “Thermal and pressure effects of hydrogen jet fires and structure integrity” will be investigated through a comprehensive set of experimental, theoretical and numerical studies. The work addresses the knowledge gaps highlighted in WP1 and the development of innovative engineering solutions for the prevention and mitigation of accident involving hydrogen jet fires. The WP is led by DTU and it aims at fulfilling the following objectives:

•   Improve the principal understanding of hydrogen jet fire on life safety provisions in underground transportation systems and their structural integrity.

•   Generate unique experimental data to support further development and validation of relevant physics models, simulations, hazard and risk assessment tools.

•   Perform numerical simulations to support the experimental campaign and get insights into hydrogen jet fire effects on life safety, property and environment protection.

•   Develop novel engineering correlations for fire safety engineering in underground transportation systems and similar confined spaces with presence of hydrogen vehicles.

•   Study thermal effects of hydrogen fire on structure integrity, erosion of road and lining materials and spalling of concrete.

•   Identify and evaluate innovative safety strategies and engineering solutions to prevent and mitigate consequences of hydrogen jet fires in underground transportation systems.

•   Underpin key RCS outputs and recommendations for inherently safer use of hydrogen vehicles in underground transportation systems by PNR research on hydrogen fires.
