Blue hydrogen is produced from natural gas. Green hydrogen is produced from electrolysis of water where the energy is comming from a renevable source. (Imagine solar panels which are directly connected to an electrolysis plant.) “Green-ish” hydrogen is produced from electrolysis of water where the energy is comming from the grid. (And thus as green as your grid is.)
