Why is hydrogen gas a good alternative for fuel? How does it work? Do you see any problems with hydrogen gas in cars?

Hydrogen has a high octane rating which is a good indication of its power output. It also has no pollution since when it burns it forms water as a product. It essentially is like an LPG system except it works at higher pressures.
This is where the problems come in since high pressures can be very lethal if anything were to go wrong. However it can be done safely since carbon fibre tanks are basicly indestructible but its the delivery points which are the concern. If a car enters a crash then you want the critical points to be well sealed otherwise an explosion can happen.
But its proven that it can be done safely but its still a concern and is the main argument against mass production of hydrogen cars. There have been cars made like the Honda which is legal in California.
The main reasons however that it hasn't been mass produced yet isn't because of the safety. Thats just a front. Its actually because it has economical viability issues since hydrogen is really cheap and can be made really simply in anyones backyard. You just perform electrolysis on water and you can make hydrogen yourself. Also oil companies have been fiercely against the proposal of hydrogen cars since that would dramatically affect their profitability.
In my opinion, hydrogen is the future since it has to be one of the best fuel sources and its proven since they use it in rockets which need the largest power output per volume. Its cheap and easy to make. And other alternatives such as electric cars just can't compare to the power requirements needed.1
