Water as a Fuel Market Report Scope & Overview:

The Water as a Fuel Market size was valued at USD 5.31 billion in 2024 and is expected to grow to USD 13.73 billion by 2032 and grow at a CAGR of 12.6 % over the forecast period of 2025-2032.

Hydrogen is completely oxidized in water. Although hydrogen is a highly energetic and combustible gas by itself, the formation of water releases some of hydrogen's useful energy. Water won't hurt you. Water can be electrolyzed into hydrogen and oxygen, however the energy required to break up a water molecule is equal to the energy generated during the oxidation of the hydrogen to form water.
