Q-LITE™ Hydrogen Tanks

Hydrogen generates power in a fuel cell, emitting only water vapor and warm air. Quantum has been an innovator in automotive hydrogen fuel storage and the first to develop a 70 MPa (10,000 psi) tank, the highest weight efficiency tank on the market. Our tanks have been used by multiple automobile OEM’s including GM, Toyota, Daimler, and others. We’ve also built tanks at various pressures for aerospace applications.
