Liebreich: ‘Blue hydrogen will be needed because green H2 alone will not be able to meet demand’

September 20, 2021

Blue hydrogen will be needed in the coming years, despite its greenhouse gas emissions, because it will simply not be possible to meet H2 demand purely with green hydrogen, according to influential independent analyst Michael Liebreich.

The founder of BloombergNEF (BNEF) calculated that just replacing the current annual global demand for grey hydrogen with the green variety would require all the wind and solar power currently installed around the world.

And he found that meeting the International Energy Agency’s hydrogen demand forecasts (in its 2050 net-zero scenario) purely with green H2 would require all the wind and solar power predicted by BNEF to be installed globally (see chart below).

“Try to meet future demand with green hydrogen and you risk absorbing all future wind and solar too, even though [existing] uses [such as fertiliser production and oil refining] should start to decline at some point,” he wrote in a LinkedIn post.

“This is why I have made my peace with blue hydrogen. I simply cannot see sufficient quantities of green hydrogen being produced fast enough and with low enough environmental impacts to meet demand.”
