Abstract

An anti-fire safety system (1) for a transport vehicle (100) having one or more storage tanks (101) storing hydrogen (H2), the anti-fire safety system (1) comprising at least: a first hydrogen-releasing system (12, 14) which is configured, notably in case of a fire event on board of vehicle (100), to release outside the vehicle hydrogen (H2) contained in at least one of the storage tanks (101); and a second release system (32, 34, 36, 38, 40, 42, 44) which is arranged to intervene and bypass the first hydrogen release system (10, 12) under predetermined operative conditions, wherein the second release system (32, 34, 36, 38, 40, 42, 44) is configured to transform by means of a chemical reaction, at least a part of bypassed hydrogen (H2) flowing outward from at least one storage tank (101), into at least one different substance.

Description

【Technical field】 [0001] The present invention relates to a fire safety system for a vehicle having hydrogen stored thereon and related vehicles equipped with such a fire safety system. 【Background technique】 [0002] As we all know, safety requirements are the most important in the field of transportation, and this requirement is more stringent and demanding for transportation vehicles on which flammable gases are stored. [0003] In particular, in the case of vehicles transporting gaseous hydrogen, or modern vehicles on which compressed gaseous hydrogen is stored for use as propulsion, such as hydrogen-powered trains, the occurrence of on-board fires may lead to the need for appropriate and A very dangerous situation to be responded to in a timely manner. [0004] For this purpose, vehicles are usually provided with fire protection systems; in particular, according to a possible solution, each tank containing gaseous hydrogen is equipped with a thermally activated pressur...
