First off, the pressure in forklift trucks is 5000 psi not 10,000 psi. How has Ballard shown what you claim?

In terms of safety, how exactly would a tank rupture? The H2 tank is encased inside the fuel cell unit which is covered in thick steel plates which is usually surrounded by the fork truck. The chance of tank rupturing is very, very remote.

Furthermore, each fuel cell power unit is designed according to safety standards which includes rigorous design and testing of the tank. Then each installation must meet the local installation safety codes and then be passed off by the local fire marshall.

No fuel is 100% safe. All fuels explode when combined with a suitable reactant and a spark. LPG is stored in a compressed tank and when it leaks, being heavier then air, it pools. But we have no problem putting these tanks right underneath open flames in our BBQs on our decks beside where our kids play.

As many studies and tests have shown hydrogen is safer then other fuels.

The water being produced being "highly corrosive" is incorrect. The water is deionized and can be poured down the drain with no treatment. Dasani (and other) used to sell deionized water for drinking but it tasted horrible so they added minerals back into it. Now it says remineralized.
