Consider the following pairs related to different types of hydrogen:1...
1. Grey Hydrogen: Incorrectly matched. Grey hydrogen is produced from natural gas but without carbon capture technology, which results in high CO₂ emissions.
2. Blue Hydrogen: Incorrectly matched. Blue hydrogen is produced from fossil fuels with carbon capture, utilization, and storage (CCUS) technology, reducing CO₂ emissions.
3. Green Hydrogen: Correctly matched. It is generated via the electrolysis of water powered by renewable energy sources like solar or wind, making it a sustainable form of hydrogen with no CO₂ emissions.
4. Pink Hydrogen: Correctly matched. It is created through electrolysis powered by nuclear energy, offering low emissions since nuclear power does not produce carbon emissions.
Thus, pairs 3 and 4 are correctly matched, making the total correctly matched pairs three.
