Amory Lovins, CEO of Rocky Mountain Institute. "Twenty Hydrogen Myths". 20 June 2003 - "Myth #7. We lack a safe and affordable way to store hydrogen in cars. This problem was solved several years ago. Such firms as Quantum (partly owned by GM) and Dynetek now sell filament-wound carbon-fiber tanks lined with an aluminized polyester bladder instead of the traditional solid metal liner (cutting weight by half and materials cost by a third). Such carbon tanks have ~9–13 times the performance of an aluminum or steel tank, but can’t corrode and are extremely rugged and safe, unscathed by crashes that flatten steel cars and shred gasoline tanks. The car isn’t driving around with highly pressurized hydrogen pipes, either, because the hydrogen is throttled to the fuel cell’s low pressure before it leaves the tank. Such aerospace- style tanks holding up to 700 bar (~10,000 psi) and proven over 1,655 bar (~24,000 psi) have been tested by GM and others in fuel-cell cars and are legally approved in Germany; U.S. authorities, who have licensed 5,000-psi (~350-bar) hydrogen tanks, are expected to follow suit shortly. Linde AG recently installed a 700-bar German filling station for Adam Opel AG."
