Scientists and start-ups believe naturally occurring hydrogen could be the next major geological breakthrough, unleashing huge amounts of hydrogen to power the clean energy transition. Researchers in the United States, Canada, and Australia are mapping and discovering potential sources of so-called geologic hydrogen, or white hydrogen, which would be mined instead of produced from electrolysis using renewable energy, the way the so-called green hydrogen is currently obtained. Several major discoveries in recent months have raised hopes that mined…
