Geothermal energy developers plan to pump 24 million gallons of water into the side of a dormant volcano in Central Oregon this summer to demonstrate new technology they hope will give a boost to a green energy sector that has yet to live up to its promise.
They hope the water comes back to the surface fast enough and hot enough to create cheap, clean electricity that isnt dependent on sunny skies or stiff breezes without shaking the earth and rattling the nerves of nearby residents.
Renewable energy has been held back by cheap natural gas, weak demand for power and waning political concern over global warming. Efforts to use the earths heat to generate power, known as geothermal energy, have been further hampered by technical problems and worries that tapping it can cause earthquakes.
Even so, the federal government, Google and other investors are interested enough to bet $43 million on the Oregon project. They are helping AltaRock Energy, Inc. of Seattle and Davenport Newberry Holdings LLC of Stamford, Conn., demonstrate whether the next level in geothermal power development can work on the flanks of Newberrry Volcano, located about 20 miles south of Bend, Ore.
...
Wells are drilled deep into the rock and water is pumped in, creating tiny fractures in the rock, a process known as hydroshearing.
...
Hydroshearing is similar to the process known as hydraulic fracturing...

Have one already in my backyard, A HEAT PUMP!!!!! Not as efficient though..
Mr boiler mechanic, in easy to understand terms water expands 1700 times when converting to steam. Am I correct ?
[ The fun here is to figure out what angle the enviro-wackos will use to protest this. Because if it works, we know they will protest it.
Will it be man-made cooling of their Earth’s core? Perhaps the interruption of the Earth’s volcanic cycle? Plate tectonics? Destruction of the magnetic field?
Put your money down now. ]
Yeah, if this does work the environuts will not like giving the human race more energy....
They will howl with an intensity that will make their current howlings look like a wimper since they are such idiot luddites.

I’m going to ask for a grant to build a giant funnel over the volcano so as to feed it water without using pumps.
Hope ya’ll support me on this.
I assume there are no fault lines near this experiment?
I'm also not by any stretch of the imagination an engineer. This whole idea sounds a bit scary to me, though. I don't think I'd want to be working on this project, or living near it, at least not at first. What if things don't go as planned, and the steam comes out somewhere other than where they think it will?
Actually this is feasible. I do not have a problem with a "research well" to prove or disprove the application. However, if proved feasible, the government needs to stay the hell out of it. If the source can be tapped economically, private enterprise will do it. Otherwise it is just another hole in the ground for Obama to poor money into.
I doubt any volcano in the world exists without fault lines nearby. Newberry is no exception.

Yes, approximately with certain variables.
It it not nice to tinker with Mother Nature....she will get even...always does.....
And yet they scream about fracking.
Not nice to messs with mother nature. When contained to the bursting point, steam can be destructive beyond belief.
This was just from the explosion of a steam locomotive
“On the morning of March 18, 1912, dozens of men at the Southern Pacific yard in San Antonio were working around an engine of the Galveston, Harrisburg & San Antonio Railroad. The men were firing up the engine to test it and ready the train for service. At 8:55 a.m., the boiler exploded, sending the engine and many tons of railroad parts flying in every direction. The pressure wave and flying debris leveled the nearby railroad shops and rippled out into the neighborhood, snapping trees and smashing into homes. As the explosion spent itself, shattered metal and human remans rained down for blocks in every direction. The front end of the engine, almost intact, came to earth seven blocks away, flattening a house and killing a woman inside. The force of the explosion could be felt miles away.
In photo at link, looks like a GBU-43/B MOAB went off.

IIRC, there are sci-fi horror movies that start something like that...
What’s hilarious about this is the fact that they are betting the ranch on water supply.
This scheme can only be perpetrated in areas with a surfeit of water. You can use salt water instead, but eventually you have to capture the steam. Eventually, you have to turn that ratwheel to get the rotor to turn through the stator.
All those impurities in the steam will eat turbines like they were twinkies at a grow house.
But hey, Thorium based nuclear works, and has only one downside - you have to actually build the plants in order to get the power from them. Good thing a really big one would be about the size of a small Costco.
This is in the Newbury National Monument. I am surprised that some environmental group has not sued to stop this in federal court.
Plus 24 million gallons of water is a lot of water to pour down a hole when you are living in the high desert. The people of LaPine , Gilchrist and Bend depend on that water in the summer to DRINK.
There is not a lot of snow pack up in the Cascades so far this winter. They do not have much water to waste. They could be in a drought this coming summer.
I thought there was a moritorium on ground water drilling in the South Central / Descutes water districts. You can’t drill for Domestic or farm use, how would this get permitted?
Just like in a nuclear power plant, you don't have to take the steam directly from the heat source to the turbine. Closed loop circulations with intermediate heat exchangers are very likely to be used.
