Are hydrogen cars the answer?

Hydrogen's Dirty Secret Although hydrogen fuel-cell cars have their advantages to petrol-fueled internal-combustion automobiles, they still don't offer the performance nor the convenience that most consumers desire. As of now, automotive engineers still have a long way to go before they could compete with gas-operated automobiles. There are plenty of obstacles that scientists have to overcome in order to make the hydrogen fuel-cell car up to par with the petrol-fueled car. There are plenty of …

…travel substantial distances (due to high density of the gas and limited space to hold it in), the high cost and constant required-maintenance of fuel cells (due their fragility to bumps or vibrations), the difficulty to "refuel" these automobiles in a timely manner, and the fact that the cars themselves are so expensive to buy altogether. All of a sudden, the hydrogen fuel-cell cars don't seem so great and economical compared to its petrol-fueled counterpart.
