Low-carbon hydrogen standards will help emissions debate

Recent debate over environmental credibility of blue hydrogen could be solved by clear and enforceable standards, says panel at Hydrogen Economist briefing

Questions about the environmental credibility of blue hydrogen could be dealt with by clear and enforceable standards for all low-carbon forms of the fuel, according to panellists speaking at a Hydrogen Economist Mena briefing in Dubai. Publication of the paper ‘How green is blue hydrogen?’ in the journal Energy Science and Engineering in mid-August caused controversy in the global hydrogen industry.
