Re: ero emissions? DropBear

The big difference between Hydrogen and the gases normally used for diving is that hydrogen under pressure reacts chemically with the tank, causing embrittlement and rupture.

Another problem is that hydrogen has a very low calorific value compared with hydrocarbons. That means either a B****y big cylinder of gas (bulky and heavy) or store the fuel as liquid with all the fuel costs of liquifaction and allow it to slowly (over a few days) boil away. **Don't store the car in a garage at home or anywhere enclosed near me if you go down this route.**

So, with a low pressure cylinder, the range will be exactly what?
