New reality for hydrogen That realism is reflected in the numbers of our latest deep dive report into the hydrogen industry. And from a low base, renewable green hydrogen from electrolysis will grow 100-fold in the same time period. This will mean more clean hydrogen in Europe and China, although the later will also turn to coal to meet hydrogen demand. DNV There is no hiding from the fact that clean hydrogen sits at the expensive end of decarbonization. That will happen not because clean hydrogen is competitive on its own, but because it will receive the support it needs.
