Large-scale blue hydrogen may still be needed, even if green H2 is cheaper, says Shell VP

By Leigh Collins 

Blue hydrogen may well be more expensive than green H2 by 2030, as some analysts predict, but large volumes of the blue variety — produced from natural gas with carbon capture and storage (CCS) — might nevertheless still be needed, Shell’s top hydrogen executive explains in a Recharge podcast.

Paul Bogers, vice-president, hydrogen, at Shell, argues that the power sector will need an awful lot of renewable energy to decarbonise, so there may simply not be enough wind or solar power available to produce green hydrogen on top of that.

Decarbonising power needs to happen first… electricity demand is going to double at least by 2050. So if then, on top of that, a significant proportion of that electricity also needs to go towards green hydrogen production, you’re making that challenge [of decarbonsing the power sector] much harder,” he explains.
