Review on studies of the emptying process of compressed hydrogen tanks
Compressed hydrogen tanks are now widely used for onboard hydrogen storage in fuel cell vehicles (FCVs). However, because of the high storage pressure and the low thermal conductivity of carbon fibre reinforced polymer (CFRP), the emptying of such tanks during driving or emergency release can cause a significant temperature decrease
Empty Tank
Empty Cars. Tank cars used for transporting liquids will often be returning the "empties" to be refilled. (They cannot be used for any other chemicals in order to avoid contamination.) But empty cars are not truly empty—they can contain up to 3% of the fully loaded volume of liquid and are known as residue cars.
Hydrogen energy future: Advancements in storage technologies
