❤OSAKA GAS Hydrogen saving technology using carbon nanotubes (compared with other 3 methods) In the case we achieve to success to save hydrogen with 10wt% 1. Compared with hydrogen saved compound metal CNTs tank 2. Compared with hydrogen compression method ** CNTs tank 500km Tank weight: 100-180kg 500km Compound metal tank when saved 5kg hydrogen Tank weight: 300kg 500km Compressed hydrogen tank 170km ** Presuming the same capacity of tanks and same level of pressure (I.e. if CNTs tanks save 5kg hydrogen) 3. Liquefied hydrogen method has problems about high liquefication cost and vaporization of liquefied hydrogen (Reference) 5kg hydrogen allows fuel cell vehicles to run about 500km 42
