Green Hydrogen- Future Energy Source

The world is in a unique and necessary phase of energy transition, where emerging low-carbon technologies are replacing existing fossil fuel assets and are shaping a new energy paradigm.

The world is in a unique and necessary phase of energy transition, where emerging low-carbon technologies are replacing existing fossil fuel assets and are shaping a new energy paradigm. Rise of technologies such as solar and wind, lithium-ion batteries, and alternative fuels have paved the way for decarbonization in various end-use sectors. However, there are certain sectors like industry and heavy transport that are hard to decarbonize using the current low- or zero-carbon technologies. The government is investing in Green Hydrogen as a clean and renewable resource for the future. Hydrogen is the most abundant element in the universe. This clean energy source is becoming more and more popular as we look for ways to reduce our reliance on fossil fuels. As the world looks to a greener future, one potential solution is green hydrogen.


Hydrogen is an energy carrier and can be used for a wide array of energy and industrial applications. It can also be stored for long time. The opportunities and challenges of hydrogen emerge from its energy characteristics.

Based on the sources and processes, hydrogen can be classified into various colours:

  • Black / Brown / Grey hydrogen

    It is produced via coal or lignite gasification (black or brown), or via a process called steam methane reformation (SMR) of natural gas or methane (grey). These tend to be mostly carbonintensive processes.

  • Blue hydrogen

    It is produced via natural gas or coal gasification combined with carbon capture storage (CCS) or carbon capture use (CCU) technologies to reduce carbon emissions.

  • Green Hydrogen

    Green hydrogen is produced using electrolysis of water with electricity generated by renewable energy. The carbon intensity ultimately depends on the carbon neutrality of the source of electricity (i.e., the more renewable energy there is in the electricity fuel mix, the “greener” the hydrogen produced).

Benefits of Green Hydrogen

The latest energy source, Green Hydrogen is a clean, renewable. It is an alternative fuel that is produced from renewable resources instead of fossil fuels. The advantages of this are many. It is a clean fuel that produces no emissions, making it a key part of the fight against climate change. Additionally, it is a versatile fuel that can be used in a variety of ways. For example, it can be used to power vehicles, as a fuel for industry, or even to store energy.The primary benefits of this energy include reducing reliance on traditional fuels, reducing green house gas emissions, and protecting the environment.

Government on  Hydrogen Energy

The Indian government is investing in the production of green hydrogen, which is much cheaper to produce than traditional hydrogen. This will help the country become a global leader in the production of hydrogen, which is needed to power our cars and bring us closer to a clean energy future. The Government of India wants to make India a Green Hydrogen Hub under the National Hydrogen Mission. Prime Minister Narendra Modi announced the National Hydrogen Mission in August 2021. The government is considering hydrogen and ammonia as the major fuels of the future. It will replace fossil fuel (petrol, diesel, coal) in future. or this, the Government of India announced the Green Hydrogen Policy in February 2022. Under this, the use of low-carbon technologies for hydrogen production will be promoted. India has set a target of producing 5 million tonnes of green hydrogen by 2030.

Fututre of Green Hydrogen In india

Hydrogen can play a critical role in India’s energy transition by enhancing its industrial competitiveness in an increasingly decarbonizing world, boosting economic development, reducing CO2 emissions, and improving public health and quality of life.India can play a leadership role at the global level in moving forward the hydrogen economy. India has a unique opportunity to become a global leader in the hydrogen energy ecosystem. With proper policy support, industry action, market generation and acceptance, and increased investor interest, India can position itself as a low-cost, zero-carbon manufacturing hub, at the same time fulfilling its goal of economic development, job creation, and improved public health.

Challenges to implementing green hydrogen

There are many challenges to implementing green hydrogen, but it is definitely possible. Here are some of the main challenges:

  1. Cost: Green hydrogen is still quite expensive to produce, so it may not be viable for large-scale use just yet.
  2. Infrastructure: We need to develop the infrastructure to support green hydrogen production and use. This includes everything from manufacturing plants to refueling stations.
  3. Education and awareness: We need to educate people about it and its benefits. This includes making sure people know how to use it and why it’s important.
  4. political support: We need political support to make green hydrogen a reality. This includes government subsidies and regulations that promote green hydrogen production and use.
  5. Technical challenges: There are still some technical challenges associated with green hydrogen production. These need to be addressed before this hydrogen can be widely implemented.

                        Despite these challenges, this is a promising technology that could help us transition to a cleaner, more sustainable future.
