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 ...

The theoretical maximum power output from a hydrogen engine depends on the air/fuel ratio and fuel injection method used. The stoichiometric air/fuel ratio for hydrogen is 34:1. At this air/fuel ratio, hydrogen will displace 29% of the combustion chamber leaving only 71% for the air.
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 ...
[2] [28] John Max of Hydrogen Fuel News believes that hydrogen may, however, be used directly, or as a feedstock for efuel, to keep classic cars on the road. [29] [30] [31] The first road vehicle powered by a hydrogen fuel cell was the Chevrolet Electrovan, introduced by General Motors in 1966. [32]
