Green Hydrogen: The Energy of the Emerging Career Options

Consider a world driven by clean, sustainable energy, in which emissions are eliminated and our planet flourishes. Green hydrogen, the fuel of the future, has brought that planet within reach.

What exactly is Green Hydrogen?

Green hydrogen is generated using sustainable energy sources such as solar and wind power. Green hydrogen, as opposed to standard hydrogen, which is created using fossil fuels, is fully carbon-free. This implies that when burned, it does not generate damaging greenhouse gases, making it a key solution to climate change.

Green hydrogen is a versatile fuel that can be utilized for a variety of purposes, including:

  • Power automobiles, trucks, buses, trains, and ships, replacing fossil fuels and lowering emissions from the transportation sector, which is a major source of air pollution.

  • Making of steel, chemicals, and other products without the use of fossil fuels, lowering industrial emissions and supporting a more sustainable manufacturing process.

  • Energy Storage: When renewable energy sources are unavailable, green hydrogen can be stored and used to generate power, assuring a consistent supply of clean energy.

In 2021, the NITI Aayog issued a paper titled "Harnessing Green Hydrogen Opportunities for Deep Decarbonisation in India." The research discusses how green hydrogen could help India meet its net-zero emissions objective by 2070. It also lists a number of obstacles that must be addressed before green hydrogen production and consumption can be scaled up in India.

The high cost of creating green hydrogen is one of the major obstacles. However, as technology advances and economies of scale are realized, the cost is likely to fall dramatically. The National Institute of Technology Aayog is working on a number of projects to encourage green hydrogen research and development in India.
