Question

The amount of Hydrogen produced in electrolysis is: *
1 point
Option 1.Thrice of Oxygen
Option 2.Twice of Oxygen
Option 3.Same as Oxygen
Option 4.Four times of Oxygen​

Answer 1

Explanation:

Considering the industrial production of hydrogen, and using current best processes for water electrolysis (PEM or alkaline electrolysis) which have an effective electrical efficiency of 70–82%, producing 1 kg of hydrogen (which has a specific energy of 143 MJ/kg or about 40 kWh/kg) requires 50–55 kWh of electricity.
