1. Toyota has been working on hydrogen-powered cars the longest, having put 23 years into the technology. Here we see its hydrogen car, the Toyota Mirai.
The automaker has been selling the Toyota Mirai in Japan since December 2014, but began sales in California in October 2015 — marking the first time hydrogen-powered vehicles were sold in the United States.
The automaker has sold 836 Toyota Mirais in California since its launch, a Toyota spokesperson told Business Insider. Toyota plans to sell 30,000 a year worldwide by 2020.
The Toyota Mirai can drive for 312 miles before needing a refuel and reaches a top speed of 111 miles per hour.
The Mirai has a frontal radar system so it can detect potential collisions and automatically employ the brakes.
The car is also equipped with a camera so it can detect lane drift. If the car detects the driver is drifting out of his lane, a noise will go off as an alert.
The car comes with two touchscreens. The top one can be used for music selection and navigation, while the one on the bottom controls the temperature and audio output.
The EPA recently gave the car an estimated range of 366 miles — the longest range of any zero-emissions vehicle. Honda says the Clarity has a refuel time of just three to five minutes.
The Honda Clarity will cost around $60,000 and has a targeted monthly lease of $500.
3. Lexus wants to unveil its hydrogen-powered car in 2020, but we have yet to hear details on its range or other specs.
It's worth noting that Lexus' parent company is Toyota.
4. Audi unveiled a concept car, the h-tron quattro, at the 2016 Detroit Auto Show that the automaker says can drive 372 miles on hydrogen alone.
Audi says the mustard yellow, fuel cell car can go from 0 to 62 miles per hour in under 7.1 seconds.
The h-tron quattro comes with a "virtual cockpit" that replaces the instrument panel and center console with digital screens.
The Audi h-tron quattro also comes with a driver assist system that projects your surroundings in real-time so you can change lanes and merge easier.
And the interior of the car offers plenty of legroom and comes with television screens for passengers in the back seat.
It's still unclear if Audi will go through with making a production version of the hydrogen car, but the automaker is exploring the technology.
5. BMW is working on a hydrogen car starting in 2020.
BMW will collaborate with Toyota to build the hydrogen drivetrains in its 2020 car.
BMW says its hydrogen car will have a range exceeding 300 miles and a refuel time of under five minutes.
6. Ford is aiming to launch the first affordable, mass-market vehicle by 2017.
In January 2013, Ford announced it was teaming up with Mercedes-Benz's parent company Daimler and Nissan to accelerate the creation of fuel cell technology. There's no word yet on how the car will perform.
