New energy carriers and additional risks for user’s safety in tunnels

A joint research project between CETU and INERIS has studied the additional risk for users ‘safety of NEC vehicles in road tunnels through hydrogen, compressed natural gas (CNG), liquefied natural gas (LNG) and electricity (lithium ion batteries). Based on occurrence rate evaluation and phenomena modelling, it was found out that electricity raised no additional risk. Concerning fire or jet fire not triggered by a fire, only hydrogen buses with 700 bars tanks or CNG buses generate a significant additional risk if the orientation of TPRD is horizontal. Vapour cloud explosion and tank rupture have a far lower occurrence than ICE (internal combustion engine) fire but their severity could be significantly higher in certain situations.
