Lincoln Composites Demonstrates 10,000 Psi TUFFSHELL Hydrogen Fuel Tank

02 June 2002

Advanced Technical Products’ Lincoln Composites division has successfully tested a Tuffshell hydrogen fuel tank with an operating pressure of 10,000-psi (700 bar) and a burst pressure of 25,000-psi (1750 bar).

The 10,000-psi tank was displayed at the California Fuel Cell Vehicle Partnership meeting in Sacramento, Calif. A 5,000-psi hydrogen fuel tank was also displayed at the Society of Automotive Engineers' (SAE) World Congress in Detroit, Mich.

Richard Rashilla, President of Lincoln Composites, stated, ""Designing and manufacturing a 10,000-psi hydrogen tank is not a big challenge for us. In fact, this achievement is the result of only a 4-week effort combined with almost 40 years of pressure vessel design and development experience. Our results speak louder than press releases when it comes to delivering what the market needs. We would like the fuel cell vehicle market to grow as quickly as this extension of our highly reliable Tuffshell fuel tanks. Our experience building high performance pressure vessels with metal or plastic liners enables us to address the Fuel Cell Vehicle market needs for affordable, high- pressure storage tanks with confidence. Our field service record of over 45,000 Tuffshell tanks in natural gas powered vehicles throughout the world demonstrates the tremendous reliability of Lincoln's plastic lined products.""

To enhance the hydrogen storage efficiency for Fuel Cell Vehicles it will be necessary to store compressed hydrogen at much higher pressures than currently used for compressed natural gas. A 10,000-psi tank would significantly increase the driving range of a compressed hydrogen fuel cell vehicle. Most automotive OEMs believe that the additional range is necessary to make fuel cell vehicles viable. Lincoln's 10,000-psi tank has an all- carbon fiber structure with a protective fiberglass over-wrap. Lincoln Composites designed this cost-effective product to meet all requirements of the Draft ISO 15869 standard for hydrogen fuel tanks.
