  This paper presents the results of a series of full-scale fire tests investigating the use of an intumescent coating material to prevent or extend the time for the initiation of thermal runaway when an electric vehicle battery casing containing lithium-ion battery (LiB) modules is subjected to an external fire.

  This paper describes a study the aim of which was to develop a model for the calculation of minimum ignition energy that only requires hydrogen-air mixture composition and temperature as inputs. The study investigates the use of laminar flame thickness to estimate the critical flame kernel. The validity of the correlation was assessed against previous experiments for hydrogen concentrations in air in the range 9-75% vol. with initial temperature equal to ambient. The applicability of the model was extended to hydrogen-air mixtures formed by releases from storage and equipment at cryogenic temperature, and the correlation was then validated against experiments carried out for the PRESLHY project on hydrogen-air mixture with temperatures in the range 123-293 K.
• A CFD analysis of liquefied gas vessel explosions

  This paper presents a study of BLEVEs for liquid hydrogen (LH2) vessels using CFD analysis. The CFD model was validated against CO2 BLEVE experiments, and hydrogen BLEVE scenarios were then simulated based on tests conducted in the 1990s for automotive applications. The parametric CFD analysis considered different filling levels as well as initial pressures and temperatures of the tank content with the aim of assessing the extent to which initial conditions influence the resulting blast wave.
