3. Main features of Type IV compressed hydrogen tank
3.1 Hydrogen impermeability
Type IV hydrogen tanks are at the heart of clean energy storage technologies. They use composite materials to store hydrogen under high pressure. These tanks play a fundamental role in the viability of hydrogen-powered vehicles: they are lighter and more resistant than traditional metal tanks. Understanding the phenomena of diffusion, solubility and permeability is essential to optimize their design and manufacture.
