Tesla is leading the electric car industry for years. The CEO of this company Elon Musk has a strong opinion about hydrogen and hydrogen fuel cells. Because previously he described hydrogen fuel-cells as “extremely silly,” But his views and opinions aren’t shared or agreed by everyone in the autos sector.

Users need to plug the vehicle into a charging point while charging the batteries of an electric car. A few years ago, the billionaire and electric vehicle magnate said at the Automotive News World Congress, “It’s just very difficult … to make hydrogen and store it and use it in a car,” Musk said. “The best-case hydrogen fuel cell doesn’t win against the current case batteries, so then, obviously … it doesn’t make sense.”

He added later, “That will become apparent in the next few years. There’s … no reason for us to have this debate, I’ve said … my piece on this, it will be super obvious as time goes by, I don’t know what more to say.”

The U.S. Environmental Protection Agency explained hydrogen fuel cell vehicles in this way, “similar to electric vehicles … in that they use an electric motor instead of an internal combustion engine to power the wheels.”

Furthermore, Fuel cell electric vehicles and hydrogen energy (FCHEA) said, “a zero-emission option with a performance they expect and no change to daily routines — long-range, quick refueling, and the ability to scale to larger platforms without adding restrictive weight and size.”

It also added, “Also, given the limitations of battery weight and recharging for long haul trucking, a significant opportunity also exists for medium- and heavy-duty delivery vans, trucks, buses, trains, and planes.

Electric vehicles have batteries that need to be charged by plugging the vehicle into a charging point, whereas fuel cell vehicles are utilizing hydrogen gas to generate their electricity onboard. Major auto-making firms including Toyota and Hyundai have produced hydrogen fuel cell vehicles. Some smaller manufacturers like Riversimple are also manufacturing hydrogen-powered cars.
