World’s most advanced technology-developed Green Hydrogen Fuel Cell Electric Vehicle Toyota Mirai was recently launched


  • Green hydrogen
    • Produced by electrolysis of water using renewable energy (like Solar, Wind) and has a lower carbon footprint.
    • Electricity splits water into hydrogen and oxygen.
    • By Products : Water, Water Vapor


  • Hydrogen is an energy carrier, not an energy source and can deliver or store a tremendous amount of energy.
  • Can be used in fuel cells to generate electricity, or power and heat.
  • Most commonly used in petroleum refining and fertilizer production, while transportation and utilities are emerging markets.
  • Hydrogen and fuel cells can provide energy for use in diverse applications, including distributed or combined-heat-and-power; backup power; systems for storing and enabling renewable energy; portable power etc.
  • Due to their high efficiency and zero-or near zero-emissions operation, hydrogen and fuel cells have the potential to reduce greenhouse gas emission in many applications.


  • India consumes about six million tonnes of hydrogen every year for the production of ammonia and methanol in industrial sectors, including fertilisers and refineries.
  • By 2030, the cost of green hydrogen is expected to compete with that of hydrocarbon fuels (coal, Crude Oil, natural gas).
  • The price will decrease further as production and sales increase. It is also projected that India’s hydrogen demand will increase five-fold by 2050, with 80% of it being green.
  • India will become a net exporter of green hydrogen by 2030 due to its cheap renewable energy tariffs.
