Hydrogen safety covers the safe production, handling and use of hydrogen, particularly hydrogen gas fuel and liquid hydrogen. Hydrogen possesses the NFPA 704 's highest rating of four on the flammability scale because it is flammable when mixed even in small amounts with ordinary air.
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.
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.
The Toyota Mirai is the biggest-selling hydrogen fuel cell car, but it still only sold about 22,000 units globally by the end of 2022. There were only 2,737 Mirais sold in 2023, and just 245 in ...
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 ...
[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]
You've probably heard of fuel cell cars. They use hydrogen gas to make electricity to power a motor that drives the car. The waste product: water vapor. The technology is clean, ...
