Most hydrogen today is produced by steam reforming from natural gas. Which means hydrogen cars are more expensive natural gas cars. There is green hydrogen produced by electrolysis of water. But it more expensive than other sources. It only makes sense when fossil fuel sources aren't allowed. Hydrogen cars are a bad idea. Now, they aren't green and don't have infrastructure. In clean electricity future, battery cars will be better. Hydrogen will be important in the future for industrial processes that need heat. And maybe for long-distance transportation like planes and ships where electricity won't work. But those only make sense with green hydrogen.
