They Went Hunting For Fossil Fuels by Laura Paddison A couple of hundred meters down, the probe found low concentrations of hydrogen. This was not a real surprise for us, Pironon told CNN; its common to find small amounts near the surface of a borehole. But as the probe went deeper, the concentration ticked up. At 1,100 meters down it was 14%, at 1,250 meters it was 20%. This was surprising, Pironon said. It indicated the presence of a large reservoir of hydrogen beneath. They ran calculations and estimated the deposit could contain between 6 million and 250 million metric tons of hydrogen. That could make it one of the largest deposits of white hydrogen ever discovered, Pironon said. The find has helped fuel an already feverish interest in the gas. White hydrogen also referred to as natural, gold or geologic hydrogen is naturally produced or present in the Earths crust and has become something of a climate holy grail. ... Ellis estimates globally there could be tens of billions of tons of white hydrogen. This would be vastly more than the 100 million tons a year of hydrogen that is currently produced and the 500 million tons predicted to be produced annually by 2050, he said. Most of this is almost certainly going to be in very small accumulations or very far offshore, or just too deep to actually be economic to produce, he said. But if just 1% can be found and produced, it would provide 500 million tons of hydrogen for 200 years, he added. |
Two grams of hydrogen releases 291.83 kilojoules per mole, about
0.08 kilowatt hours. So, if we replace half the energy used by mankind,
let's say coal and natural gas, then we need 80,000 terawatt hours.
You need two billion tons per year. Well, maybe a small contribution then.
