Many auto companies are investing heavily in hydrogen fuel cells but battery-electric vehicles are just as compelling

It's the most commonly-occurring element in the universe, it can be burned in a combustion engine or used to fuel electric motors, and it's vastly cleaner emissions-wise than gasoline. The automotive industry seems to have settled on hydrogen as the magic bullet solution to the looming energy crisis, and each year we see a number of fuel cell concept cars showcased by the major manufacturers -- but it's a technology with some serious hurdles to overcome before it becomes viable. So how does hydrogen compare to batteries as a means of propelling transport in the future?


Is hydrogen the answer? Honda is one of many major auto companies that think so -- stating in a recent release on their FCX concept that "Hydrogen will fuel the next generation of global vehicles. It's a fact accepted by the entire industry. And given that it's the most commonly-occurring element in the universe, supply is not an issue."

But what about the new and coming generations of plug-in electric vehicles? As with Hydrogen fuel cell vehicles, its early days yet, but pure electric vehicles seem to have a few strong points of their own. So, with a focus on fuel cells rather than hydrogen fueled internal combustion engines, let's take a look at the set of requirements a transportation fuel source has to meet to be viable, and see how hydrogen and batteries compare...
