The colours of hydrogen. Hydrogen has many colours, and we frequently refer to green, turquoise, blue and grey hydrogen. Since this versatile energy carrier is actually a colourless gas, one might well ask what these colours actually mean. We show what colours hydrogen is classified as, what the meaning behind these colours is, and how they are
