Green hydrogen as future sustainable energy sourceConcept of green hydrogen energy, Molecule of H2 in hands shine on a backdrop with stars

The ever-increasing population of the world demands more energy day by day. Conventional energy sources are going to deplete day by day and cause climate change. The future of mankind depends on the use of renewable energy sources or sustainable energy like the use of solar energy, wind energy, geothermal energy, hydroelectric energy, green hydrogen, etc. Currently, the world is taking steps towards using and making renewable energy sources popular. Slowly and steadily governments encourage citizens to use renewable energy in their day-to-day lives in order to save Mother Earth from climate change like global warming – greenhouse effects.

Why green hydrogen?

Hydrogen is considered a green energy source because it can be produced through the electrolysis of water using renewable energy sources such as solar or wind power. The product is known as “green hydrogen,” which produces hydrogen without emitting greenhouse gases, making it a clean and sustainable alternative to fossil fuels. Additionally, when hydrogen is used as a fuel, the only byproduct is water, making it a potentially valuable source of clean energy for transportation, heating, and power generation.

Several countries around the world are currently using it as a clean and sustainable energy source. Some examples include:

  1. Germany: The German government has set a goal to produce 5 GW of it by 2030 and is investing in research and development to make it cost-competitive with fossil fuels.
  2. Japan: Japan is investing in it as part of its efforts to reduce greenhouse gas emissions and achieve its renewable energy goals. The Japanese government has set a target to produce 800,000 tons of it by 2030.
  3. South Korea: South Korea has set a target to produce 6.2 GW by 2040 and is investing in research and development.
  4. Australia: Australia is investing in it as part of its efforts to reduce greenhouse gas emissions and achieve its renewable energy goals. The Australian government has set a target to produce 1 GW by 2030.
  5. United States: The United States has set a target to production of 10 GW by 2030, and is investing in research and development.
  6. Canada: Canada has set a target to produce 5 GW by 2030.

India’s green hydrogen projects

India has announced plans to increase its use of it as part of its efforts to reduce greenhouse gas emissions and achieve its renewable energy goals. The Indian government has set a target to produce 5 GW of hydrogen by 2030 and has established a National Hydrogen Energy Mission to develop the hydrogen ecosystem in the country.

As part of this mission, several green hydrogen projects have been proposed and are under development in India. For example, the Indian Oil Corporation is planning to set up a green hydrogen production facility in Gujarat and the National Hydrogen Energy Board (NHEB) is working on a pilot project to produce it from renewable energy sources in Tamil Nadu. Additionally, The Indian Renewable Energy Development Agency has also announced plans to establish a Green Hydrogen Production and Refueling Demonstration Project, in partnership with private companies.

India is also looking to import it from other countries, as part of its plan to reduce the cost of the technology and to make the hydrogen infrastructure more robust. In summary, India is actively working on several projects and has set ambitious targets to increase its use of this clean energy source.

These are just a few examples, but many other countries around the world are also exploring the use of it as a clean energy source. The use of green hydrogen is likely to grow in the coming years as the cost of producing green hydrogen continues to decrease, making it more competitive with fossil fuels.

FAQs:

1. What is green hydrogen and how is it different from other types of hydrogen?

Green hydrogen is produced from renewable energy sources such as wind or solar power, while other types of hydrogen, such as gray and blue hydrogen, are produced from waste fossil fuels and carbon.

2. Why is it considered a clean energy source?

Green hydrogen is considered clean because its production produces no carbon emissions, making it a sustainable and environmentally friendly energy carrier.

3. How is green hydrogen produced and what are the main technologies involved?

Green hydrogen is typically produced through a process called electrolysis, in which water is split into hydrogen and oxygen using electricity generated from renewable sources. Advanced electrolysis technologies such as PEM and alkaline electrolyzers are commonly used.

4. What are the main applications of it?

Green hydrogen has many applications, including fuel cell vehicles, industrial processes, energy storage, and grid balancing, making it a versatile clean energy solution. 

5. What are the challenges and barriers to the widespread adoption of green hydrogen?

Challenges include high production costs, the need for widespread infrastructure, and the instability of renewable energy sources. Addressing these challenges is critical to increasing green hydrogen production.

6. Are there any notable projects or initiatives driving green hydrogen adoption globally?

Yes, many countries and organizations have launched initiatives to promote green hydrogen, including large-scale hydrogen production projects, research and development efforts, and incentive policies.

7. How does green hydrogen help reduce greenhouse gas emissions?

Green hydrogen can replace fossil fuels in many different sectors, reducing emissions related to transportation, industry, and power generation, and helping to fight climate change.

8. What is the current cost of producing green hydrogen and how are these costs expected to change in the future?

The cost of producing green hydrogen is gradually decreasing thanks to technological advances and economies of scale. Industry experts predict production costs will become more competitive in the coming years.

9. Can green hydrogen play a role in achieving a carbon-neutral future?

Yes, It is seen as an important part of the transition to a carbon-neutral economy, as it could provide a clean energy source for sectors struggling to decarbonize.

10. How can individuals and businesses get involved in this sector?

Individuals and businesses can support this industry by investing in renewable energy projects, advocating for supportive policies, and seeking opportunities to integrate hydrogen technology into their operations.
