Green hydrogen involves producing hydrogen gas using renewable or other low-carbon electricity. For example, electricity generated by wind farms or solar parks is used to power an electrolyzer, which chemically splits water into its constituent parts, hydrogen and oxygen. The hydrogen fuel can be stored and transported by pipeline or road to supply end users in the industrial or transportation sectors. When used to power fuel cell vehicles, for example, the use of hydrogen to generate electricity emits only water vapour and warm air as waste products, making it a zero emissions vehicle.
