Why Are Hydrogen Engines a Bad Idea?
The Biggest Reason Why Hydrogen-Combustion Engines Are No Good? They Create Nitrogen Oxide, Which Isn't Good for People or the Environment. Even Though Carbon...

Hereof, why Hydrogen cars are a bad idea?
In theory, just like a hydrogen fuel cell, a hydrogen combustion engine should not produce the environmentally damaging carbon emissions because hydrogen fuel does not have any carbon in it. Yet, because of the combustion process involved with hydrogen combustion engines, it actually produces nitrogen oxide.
Furthermore, can a car engine run on hydrogen? Hydrogen fuel-cell vehicles, effectively run on batteries powered by hydrogen instead of the electric power grid. The fuel cell converts the hydrogen and oxygen in the air into water, and in the process it produces electricity. As long as hydrogen and oxygen keep flowing into the fuel cell, it never goes dead.
Likewise, people ask, why don't we use hydrogen as a fuel?
First, hydrogen is not as energy-dense as other fuels, meaning that you need a whole lot of it to do a little bit of work. Fuel cells are far more efficient than internal combustion engines, and a hydrogen fuel cell has cleaner emissions than an internal-combustion hydrogen engine.
What are the problems with hydrogen fuel cells?
The only real problem is the issue of safety. Hydrogen is highly flammable – more so than regular fuel – and is harder to contain than oil. This means that any car fitted with a hydrogen fuel cells is a lot more likely to blow up or set on fire if it is exposed to extreme heat, if it breaks down or if it overheats.
