It will undergo its first trial run on the Jind-Sonipat route in Haryana.

• The engine has been made by Indian Railways using indigenous technology, having a capacity of 1,200 horsepower. 
• Only 4 countries (Germany, France, Sweden, and China) in the world have hydrogen-powered trains, producing between 500 to 600 horsepower.

Hydrogen as a Clean Fuel 

• Hydrogen is a clean & versatile energy source with potential to decarbonize transportation, industry, & power generation.
• Types 
  • Blue Hydrogen: Produced from natural gas with a process of steam methane reforming, where natural gas is mixed with very hot steam and a catalyst. Carbon dioxide is also produced as a by-product.
  • Grey Hydrogen: Produced from natural gas via steam methane reforming (SMR). It emits significant carbon dioxide (CO₂).
  • Green Hydrogen: Produced through water electrolysis powered by renewable energy sources (e.g., wind, solar) with no harmful by-products.
  • Pink hydrogen: Generated through electrolysis powered by nuclear energy.

Advantages 

• Abundance: It contributes 75% of the mass of the universe.
• Clean Energy: Water is the only byproduct when used in fuel cells.
• Highly Efficient when Compared to Other Energy Sources

Challenges

• Currently expensive, Storage and transportation of hydrogen is more complex, safety (highly flammable), etc.
