Which of the following pairs is/are correctly matched? Black hydrogen ...
Black hydrogen: Produced by use of fossil fuel
Black hydrogen is not produced by the use of fossil fuels. It is actually a term used to refer to hydrogen produced from fossil fuels like coal or natural gas with carbon capture and storage technology to reduce carbon emissions.

Grey hydrogen: Produced through electrolysis, but using energy from nuclear power sources
Grey hydrogen is produced through steam methane reforming, a process that converts natural gas into hydrogen. It is not produced through electrolysis using energy from nuclear power sources.

Pink hydrogen: Produced through Natural Gas
Pink hydrogen is produced through electrolysis using renewable energy sources like wind or solar power. It is not produced through natural gas.
Therefore, the only correct statement is that Pink hydrogen is produced through natural gas.

Which of the following pairs is/are correctly matched? Black hydrogen ...
Only Statement 1 is correct.
‘Green hydrogen’, the emerging novel concept, is a zero-carbon fuel made by electrolysis using renewable power from wind and solar to split water into hydrogen and oxygen. This ‘Green hydrogen’ can be utilised for the generation of power from natural sources — wind or solar systems — and will be a major step forward in achieving the target of ‘net zero’ emission.
Black hydrogen is produced by use of fossil fuel, whereas pink hydrogen is produced through electrolysis, but using energy from nuclear power sources.
Grey hydrogen is produced from natural gas.
