8 statements about Geologic Hydrogen, every show
Johnson: Serpentinization is the primary mechanism generating underground hydrogen
“Most people believe serpentinization is the main way that hydrogen forms under the ground, and look, we have hydrogen seeps have, that have been found and detected all over the planet.”
Johnson: Mining companies understand geologic hydrogen source rocks best
“It's the mining companies that actually know the most about this type of hard rock that serves as a source rock for hydrogen.”
Johnson: Geologic hydrogen extraction costs should match natural gas extraction
“If you can find hydrogen under the ground, the reality is you should be able to produce it from a volumetric standpoint at a similar cost that we produce natural gas out of the ground.”
Johnson: USGS estimates geologic hydrogen resources could reach trillions of tons
“The USGS put out an estimate that this could be on the order of trillions of tons. You know, hundreds of years of energy.”
Johnson: Commercial hydrogen discoveries require 10k-50k tons annually over decades
“If you want to produce liquid hydrogen, you got to be producing 10,000 tons per year, give or take. If you want to be, you know, producing ammonia, you know, you're probably in the neighborhood of like, 50,000 tons per year is a good amount of hydrogen. So I w…”
Johnson: Geologic hydrogen rivals nuclear fusion in potential decarbonization impact
“I think geologic hydrogen should be mentioned in the same breath”
Lacey: Economically feasible geologic hydrogen extraction is probably decades away
“So if this is something that's feasible, it's probably decades out, but worth paying attention to.”
