Hydrogen fuel enhancement from electrolysis (using automotive alternators) has been promoted for use with gasoline-powered and diesel trucks, [14] [15] [16] although electrolysis-based designs have repeatedly failed efficiency tests and contradict widely accepted laws of thermodynamics (i.e. conservation of energy). Proponents, who sell the ...
Pros and Cons of Hydrogen Fuel-Cell Electric Vehicles PRO: The technology works. The California-only Toyota Mirai has a range of up to 402 miles and can be refueled nearly as quickly as a gasoline ...
Using hydrogen's lower heating value, the maximum fuel cell efficiency would be 94.5%. [33] The efficiency of a hydrogen combustion engine can be similar to that of a traditional combustion engine. If well optimized, slightly higher efficiencies can be achieved. The comparison with a hydrogen fuel cell is interesting.
In Brazil, 65% of flex-fuel car owners were using ethanol fuel regularly in 2009, [25] while, the actual number of American FFVs being run on E85 is much lower; surveys conducted in the U.S. have found that 68% of American flex-fuel car owners were not aware they owned an E85 flex.

Since hydrogen station growth has stalled and hydrogen prices exploded, fuel cell sales have stalled too. In the first half of 2023, 1,765 such cars were sold or leased. This year's first half: 298.
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.
[B]y 2025 the last hold outs should likely be retiring their fuel cell dreams.” [151] A 2019 video by Real Engineering noted that using hydrogen as a fuel for cars does not help to reduce carbon emissions from transportation. The 95% of hydrogen still produced from fossil fuels releases carbon dioxide, and producing hydrogen from water is an ...
