The Forgotten History of Hydrogen Engines
The first hydrogen engine was proposed in
1820 by Reverend W. Cecil, but by the
1870s, gasoline took over, thanks to the invention of the
carburetor. While hydrogen became essential for
rocket fuel in space exploration, its role in transportation faded. With today’s push for
clean energy, the big question remains—can hydrogen make a comeback in internal combustion engines?

Hydrogen vs. ICE & EVs – How Do They Compare?
Hydrogen engines offer unique benefits like
high flame speed, wide flammability, and low emissions, but they struggle with
efficiency. While gasoline engines are
11-27% efficient, hydrogen fuel cells reach
40-60% efficiency, and
EVs powered by renewables can exceed
70% efficiency. Hydrogen combustion
still produces NOx emissions, raising questions about its environmental advantage over
battery-electric vehicles.

Why Hydrogen ICE Vehicles Never Took Off
In
2023, only
14,500 hydrogen cars were sold globally, compared to
14 million EVs. Despite some interest in
Hâ‚‚-powered trucks and off-road vehicles, hydrogen combustion faces major challenges:
high costs, poor fueling infrastructure, and competition from more efficient fuel cell vehicles (FCEVs). Industry predictions estimate only
10,000 hydrogen ICE trucks by 2030—a tiny fraction of the global market.
