Hydrogen-powered automobiles have been an idea for a while, and yet despite the many advances in technology, hydrogen cars haven't caught on.

One reason why is because hydrogen fuel-cell technology doesn't have enough hydrogen infrastructure.

Hydrogen is the most abundant element in the world, and as a bonus, when it's burned, the only thing emitted from the tailpipe is water.

Many individuals believe that hydrogen-powered vehicles are an essential step in promoting sustainable transportation. However, while hydrogen fuel cell cars don't emit greenhouse gasses, hydrogen isn't entirely clean, and on top of that, hydrogen fueling stations are still very scarce, limiting the cars' success.

Overall, hydrogen cars have numerous advantages, but the biggest disadvantage is the lack of hydrogen infrastructure.

Currently, hydrogen fueling stations are rare. There are only 9 in the entire state of California, which ultimately makes hydrogen Automotives impractical because hydrogen can't just be pumped into your average gas tank.

Ultimately, in order for hydrogen alternative vehicles to become a real option, hydrogen infrastructure needs to grow, and if that happens, hydrogen-powered vehicles could be a great option for those looking to reduce their carbon footprint.
