1. What makes hydrogen a desirable source of power?
Hydrogen is abundant, produces minimal pollution when burned, and can store and deliver energy in a usable form.
2. How is hydrogen produced, and what are the types?
Common methods include steam methane reforming and electrolysis. Types include grey, blue, green, and pink hydrogen, categorized based on production methods and carbon emissions.
3. Why is green hydrogen considered the most sustainable option?
Green hydrogen is produced through water electrolysis using renewable energy sources like wind or solar, emitting no CO2.
4. What are the potential uses of hydrogen?
Hydrogen can be used in fuel cells for electricity and heat, to store renewable energy, and as a feedstock in industries for chemicals and fuels production.
5. What challenges does hydrogen usage face?
Challenges include storage and transport due to its low energy density, high production energy requirements, and the current cost of fuel cells compared to combustion engines.
6. Why is green hydrogen crucial for the energy transition?
Green hydrogen can store and deliver renewable energy, decarbonize hard-to-electrify sectors, and contribute to energy security by diversifying energy sources.
7. How does pink hydrogen differ from green hydrogen?
Pink hydrogen is produced using nuclear power for electrolysis, considered low-carbon but dependent on the sustainability of nuclear energy generation and waste management.
8. What role does green hydrogen play in reducing greenhouse gas emissions?
It can help decarbonize sectors like heavy industry and long-distance transport, crucial for reducing emissions and combating climate change.
