Hydrogen fuel cell cars like the Toyota Mirai contain Kevlar-armored tanks that store hydrogen at 700 times the pressure of the Earth’s atmosphere. But this is hard to do on a large scale for ...
Although the automotive industry seems like it’s slowly making a shift towards battery-powered vehicles, hydrogen fuel cell vehicles could be another great alternative to gas-powered cars.
Hydrogen combustion cars are not commercially available. [citation needed] In the light road vehicle segment, by the end of 2022, 70,200 fuel cell electric vehicles had been sold worldwide, [25] compared with 26 million plug-in electric vehicles. [26] In 2023, 3,143 hydrogen cars were sold in the US compared with 380,000 BEVs. [27]
If well optimized, slightly higher efficiencies can be achieved. The comparison with a hydrogen fuel cell is interesting. The fuel cell has a high efficiency peak at low load, while at high load the efficiency drops. The hydrogen combustion engine has a peak at high load and can achieve similar efficiency levels as a hydrogen fuel cell. [34]
[153] [154] A 2021 assessment by CleanTechnica concluded that while hydrogen cars are far less efficient than electric cars, the vast majority of hydrogen being produced is polluting grey hydrogen, and delivering hydrogen would require building a vast and expensive new infrastructure, the remaining two "advantages of fuel cell vehicles ...
There are only about 17,000 hydrogen-powered vehicles on U.S. roads right now, and all of them are in California. Meanwhile, EVs are out there in the millions.
The Hype about Hydrogen contends that global warming and U.S. reliance on foreign fuel imports cannot be solved by the hypothetical hydrogen economy that has been advanced as a possible solution to these problems, and that "neither government policy nor business investment should be based on the belief that hydrogen cars will have meaningful commercial success in the near or medium term."
That's a lot of cars — 1.78 million new vehicles were sold in California last year. Since hydrogen station growth has stalled and hydrogen prices exploded, fuel cell sales have stalled too.
