Geothermal Energy is Poised for a Big Breakout
Eavor was recently mentioned in an excellent piece from Cloud Clarity 360.
"Closed-loop geothermal systems have been around for decades, but a few startups have recently amped them up with technologies from the oil and gas industry. One such company, started by investors with experience in oil and gas, is the Alberta-based Eavor.
In Eavor’s planned system, called an “Eavor-Loop,” two vertical wells around 1.5 miles apart will be connected by a horizontally arrayed series of lateral wells, in a kind of radiator design, to maximize surface area and soak up as much heat as possible. (Precise lateral drilling is borrowed from the shale revolution, and from the oil sands.)
Because the loop is closed, cool water on one side sinks while hot water on the other side rises, creating a “thermosiphon” effect that circulates the water naturally, with no need for a pump. Without the parasitic load of a pump, Eavor can make profitable use of relatively low heat, around 150°C, available almost anywhere about a mile and a half down."
This is only a small segment of the Eavor mentions and an even smaller segment of the entire article.,
