Hydrogen is hazardous for 2 reasons.
1. It can exclude oxygen which means you can suffocate (this is true for almost any gas).
2. It is VERY flammable (or explosive) when mixed with air or oxygen. It is flammable from a very low concentration in air to a very high concentration in air which is unique. Most flammable or explosive gases are only explosive in a limited range of concentrations.
It is also very light (the lightest gas) and will accumulate in high trapped places (like up at the ceiling).
Handled properly it isn't especially reactive or dangerous though.

A hydrogen tank on a car isn't much more dangerous than a fuel tank on a car. There are different ups and downs for explosions. When a liquid fuel tank ruptures the gasoline spills and stays on the ground. It is a present threat to any ignition sources near the ground. When a gaseous fuel tank ruptures, the fuel blows away. It is dangerous for about 2 minutes after the rupture. Simply creating a hole in the tank won't cause an explosion either. There has to be both oxygen and hydrogen in the tank for an explosion. The tank has to rupture long enough for the air to mix before finding a spark. Just hope the car crash isn't into a building. Then the ruptured fuel tank will spill the hydrogen into a contained space. That is much more dangerous. Hydrogen is produce from two sources: 1) oil or natural gas products 2) water. Oil has a much more dense concentration of hydrogen gas and is the preferred medium to take the gas from. I believe water makes up about 10 or 20 percent of world production, but don't have source to back that up. A better direction to look at in butanol as a fuel source. It is a better fuel source than gasoline or ethanol. It doesn't evaporate as quickly as gasoline mixes. It is far less corrosive than ethanol and in some cases gasoline. And it has only slightly less energy than normal gasoline. It would be a straight replacement. There are two different efforts to build pilot plants for producing butanol from agricultural waste currently that I know of. Biodesiel beats it, but desiel engines aren't popular.

It's very reactive. Reference_The Hindenberg
