FAQ.
A hydrogen engine operates by using hydrogen gas as its primary fuel source. It works through a process called combustion, where hydrogen mixes with oxygen from the air to generate energy.
In a hydrogen engine, the hydrogen gas is typically stored in a tank and then delivered to the engine’s combustion chamber. When the hydrogen mixes with oxygen, either through an intake or directly injected into the chamber, it creates a highly combustible mixture.
When ignited, this mixture undergoes combustion, producing energy in the form of heat. This energy is then converted into mechanical energy, which powers the engine and drives the vehicle or machinery.
The key benefit of a hydrogen engine is that its only emission is water vapor, making it an environmentally friendly alternative to traditional combustion engines that produce greenhouse gases.
