A frontal road collision between a truck transporting pressurised hydrogen gas and a carBoth vehicles were projected into the fields, on each side of the road. No leakage of hydrogen gas was observed…
Collision between a hydrogen and fuel cells bus and a private car. The car was overtaking the bus and damaged its rear, left side.
The passenger car rolled down the road without driver and hit the hydrogen bus.
The driver of a hydrogen bus reversed into a post.There was some small material damage to the bus. No leakage of hydrogen (or other gases) occurred.
The bus drove into the garage and collided with a folded-out safety barrier. The upper corner of the roof was damaged. Also the first hydrogen tank was affected by the collision but without any…
