Types of hydrogen Green hydrogen is hydrogen gas produced through electrolysis of water — an energy intensive process for splitting water into hydrogen and oxygen— using renewable power to achieve this. Brown hydrogen is produced using coal where the emissions are released to the air. Grey hydrogen is produced from natural gas where the associated emissions are released to the air. Blue hydrogen is produced from natural....Read More
