1. What is the source of grey hydrogen?
• Grey hydrogen is derived from natural gas through steam methane reforming (SMR).
2. How does green hydrogen differ from grey hydrogen regarding CO2 emissions?
• The carbon dioxide generated in grey hydrogen production is not captured. In contrast, green hydrogen, produced through renewable sources, does not emit CO2.
3. Why is green hydrogen considered a potential game-changer for a low-carbon economy?
• Green hydrogen offers a solution to decarbonise various industries, especially those seen as “hard to abate” such as cement, steel, and petrochemicals.
4. What are the challenges associated with green hydrogen?
• While there's optimism and investment in green hydrogen, challenges exist, especially its cost, which is 2 to 3 times that of grey hydrogen.
5. How is India uniquely positioned in the green hydrogen economy?
• India has a strong electricity grid, is rich in renewable energy resources, has a skilled workforce, and aims to reduce dependency on imported fossil fuels, making it ideal for green hydrogen production.
6. How can green hydrogen impact India's energy dependency?
• Investing in green hydrogen can help India decrease its reliance on imported fossil fuels, leading to reduced trade deficits and enhanced energy independence.
7. In conclusion, what is the broader significance of green hydrogen in the global context?
• Green hydrogen has the potential to reshape industries, economies, and our approach to sustainability, leading to a more sustainable future.
These FAQs offer a comprehensive overview of the key insights from the discussion on the Green Hydrogen Revolution, focusing on its global and Indian context.
