Disused Oil Wells Could Enhance Compressed Air Storage
The title of this post, is the same as that of this article on The Engineer.
This is the sub-heading.
A new study has shown how geothermal energy in abandoned oil and gas wells can boost the efficiency of compressed air energy storage by nearly 10 per cent.
These are the first two paragraphs.
Developed by researchers at Penn State University, the geothermal-assisted compressed air energy storage (GA-CAES) system harnesses the existing infrastructure of abandoned oil and gas wells (AOGWs). Compressed air is pumped into the wells, where geothermal heat raises its temperature and compresses it further. Published in the Journal of Energy Storage, the study showed how geothermal energy could increase round-trip efficiency by 9.5 per cent.
“This improvement in efficiency can be a game changer to justify the economics of compressed-air energy storage projects,” said corresponding author Arash Dahi Taleghani, Professor of Petroleum and Natural Gas Engineering at Penn State.
The Professor also says it could be a “win win situation!”
Trump must have nightmares about stories like this, especially, when the scientists have a name, that labels them as an immigrant.
The Anonymous Widower 
Er… Oil based fuel, air, high compression and raised temperature – isn’t this the principle of operation of a diesel engine?
Might be safer using nitrogen or carbon dioxide.
