Quantum Fuel Systems Technologies Worldwide has delivered its new, next-generation 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 tank is based on Quantum’s Type IV (polymer-lined, all-composite) ultra-light weight tank technology, incorporating advancements in materials, material utilization, and optimized design, yielding benefits proprietary to its customer.
In developing its new high-pressure hydrogen storage tanks for these fuel cell buses, Quantum also focused on design for cost and manufacturing as its customers move from prototype vehicle demonstrations to production intent fuel-cell vehicle programs. Quantum was able to achieve substantial reductions in material cost and improvements in both material utilization and manufacturing efficiency compared to its prior generation hydrogen tanks.
In addition, Quantum’s next-generation Type IV compressed hydrogen storage tanks were successfully tested and validated to operating conditions beyond current industry standards, addressing extreme temperature conditions found to occur in real world experience from prototype fuel cell vehicle demonstrations. The validation testing resulted in certification of these tanks to the new Japanese Hydrogen High Pressure Vessel Codes, Reiji Kijyun.
Quantum has product commercialization alliances with General Motors, AM General, and Sumitomo. Quantum’s customer base includes General Motors, Toyota, Opel, Hyundai-Kia, Suzuki, Ford, DaimlerChrysler, AeroVironment, and the US Army.
