Which statement correctly describes green hydrogen?

Which statement correctly describes green hydrogen?

• A. It is produced via steam methane reforming without CCS.
• B. It is produced by combining natural gas with CCS in a new method.
• C. Green hydrogen is produced via electrolysis using renewable electricity.
• D. It is produced exclusively from fossil fuels with no CCS.

Answer: (C)

Green hydrogen is hydrogen produced by electrolysis of water using electricity from renewable sources. In electrolysis, electricity splits water into hydrogen and oxygen, and if that electricity comes from wind, solar, hydro, or other renewables, no carbon is emitted during production. This is why electrolysis powered by renewables is considered the cleanest hydrogen production route. Other methods rely on fossil fuels and emit CO2 (unless carbon capture is used), so they aren’t green.
