Combustion of Hydrogen Gas

2H2 + O2 → 2H2O

Genel Bakış

Hydrogen gas burns in oxygen to produce water with no carbon-containing products. This makes hydrogen the ultimate clean fuel. The reaction produces a very hot, nearly invisible flame. Hydrogen-oxygen mixtures are explosive within a wide flammability range (4-75% H2 in air).

Günlük Örnek

Hydrogen fuel cell vehicles like the Toyota Mirai emit only water vapor from the tailpipe, as the hydrogen effectively combusts electrochemically.

Endüstriyel Önemi

Hydrogen combustion is central to the hydrogen economy for clean energy. It powers rocket engines (Space Shuttle main engine used liquid H2/O2) and fuel cells.
