Green Hydrogen UPSC NOTE


  • Green hydrogen is primarily produced through a process called electrolysis.

  • The main ingredient used for electrolysis is water, which is made up of two elements: hydrogen and oxygen.

  • During electrolysis, an electric current is passed through the water, causing the water molecules to split into hydrogen (H2) and oxygen (O2) gases.

  • Electrolysis takes place inside a device called an electrolyzer, which consists of two electrodes—a positively charged anode and a negatively charged cathode—immersed in water.

  • When the electric current flows through the water, the negatively charged electrode (cathode) attracts positive ions (protons), while the positively charged electrode (anode) attracts negative ions (electrons).

  • At the cathode, protons gain electrons and combine to form hydrogen gas (H2).

  • At the anode, oxygen gas (O2) is produced as a byproduct of the electrolysis process.

  • To ensure the process is green and sustainable, the electricity used for electrolysis should come from renewable energy sources such as solar or wind power.

  • This helps minimize carbon emissions and reliance on fossil fuels.

  • Green hydrogen is distinguished from gray hydrogen, which is produced using fossil fuels and releases carbon dioxide as a byproduct. 

  • Green hydrogen, on the other hand, has no carbon emissions and offers a clean energy alternative.
