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. Green hydrogen matters because it offers a solution for decarbonizing sectors that are otherwise hard to electrify. Renewable electricity and batteries work well for cars and home power, but heavy industries and long-distance transport pose a bigger challenge. Industries like steel, cement, refining, chemicals, and fertilizer production require high heat or chemical feedstock that green hydrogen can provide without fossil fuels businesswire.com businesswire.com. Likewise, fuel-cell hydrogen can power long-haul trucks, ships, and potentially aviation where batteries are too heavy or have insufficient range. As one expert put it, hydrogen at scale can act as the “Swiss army molecule that could do anything” in a clean energy system theguardian.com – from storing surplus solar power to fueling
