Green hydrogen refers to hydrogen fuel produced using renewable energy to split water molecules via electrolysis, yielding hydrogen gas with zero greenhouse gas emissions businesswire.com. It contrasts with traditional “grey” hydrogen, made from natural gas via steam reforming, and “blue” hydrogen, which is similarly made from fossil fuels but with carbon capture to reduce emissions globenewswire.com. Because green hydrogen’s production doesn’t emit carbon and its use only produces water vapor, it is seen as a crucial clean energy carrier for a sustainable future businesswire.com.
