The author of this article makes some good points on that subject:

“Secondly, both forms of clean hydrogen must combine to provide the necessary volumes at the conditions needed to achieve emission reductions in sectors where renewables alone will not suffice, and deep decarbonization through electrification is difficult to achieve. Examples are heavy, long-haul land and maritime transport sectors, steel, cement, chemical, and even refining.

Indeed, large industrial-scale production of blue hydrogen will through economies of scale help the integration of smaller-scale green hydrogen, whether it is produced from surplus renewable electricity or dedicated electrolysis value chains. We need both forms of sustainable hydrogen to succeed in building the necessary infrastructure for hydrogen in time for all sectors of the economy to contribute to tackling climate change.”
