- Hydrogen is no more dangerous than any other flammable gas and much less
- dangerous than gasoline. Hence, storing it involves no greater hazard
- than the propane bottle that you probably have in your garage to run
- your camp stove or propane torch. When stored as a hydride it is
- probalby less dangerous because of the low pressure involved.
-
- Like the hysteria about radioactivity, most people have seen pictures of
- the Hindenburg disaster and believe hydrogen is the worst. But the facts
- are that two thirds of the people on the ship walked away from the
- disaster and of the 35 people who died, three were burned by diesel
- fuel and other flamable materials and 32 were killed by jumping to the
- ground.
-
- A hydrogen gas pipline is probably the the most efficient way to
- transport energy and at the other end you can convert it to electricity
- and fresh water with 96% efficiency via PEM fuel cells - considerably
- more efficient than high voltage DC transmission lines.
