Quantum Fuel Systems Technologies Worldwide Inc. has delivered its type IV compressed hydrogen storage tanks to a fuel cell bus manufacturer for use in fuel cell buses to be operated on public routes. The tanks are based on Quantum's lightweight, polymer-lined, all-composite tank technology, and the company said it achieved substantial reductions in material cost improvements, as well as improvements in material utilization and manufacturing efficiency compared to its prior-generation hydrogen tanks.

The tanks were tested and validated to address extreme temperature conditions and are certified to Japan’s Reiji Kijyun hydrogen high pressure vessel codes.
