Hydrogen Storage
Hydrogen must be stored at extremely high pressures to achieve practical energy density. Composite pressure vessels, typically made with carbon fiber reinforcement, provide the strength required to safely contain that pressure while dramatically reducing weight compared with steel, making hydrogen storage feasible for transportation and other weight-sensitive applications.
