Penn State: Store, Use Compressed Air in Old O&G Wells for Powergen

You have to hand it to the environment-left; they sure are creative. How do they think these things up? Penn State researchers, committed to the religion of eliminating fossil fuels and the 100% adoption of unreliable renewables, are looking for a way to use old/depleted oil and gas wells---of which there are hundreds of thousands in PA (an estimated 3.9 million nationwide). The latest Penn State research proposes blowing compressed air down old wells and storing it underground where the earth's heat will warm it, further compressing it (giving it an extra 9.5% of "efficiency"). And when electricity is needed, let the air escape, running big power turbines. Just one teeny, tiny problem: It costs so much that nobody will do it.
